    Talk Title: Unlocking the Future: Designing Next-Generation AI Chips with AI Algorithms

    Abstract: Data, chips, and algorithms form the backbone of the AI revolution, demanding hardware as sophisticated as orchestrating a bustling city. In this technological realm, GPUs and high-bandwidth memory are essential yet frequently strained by the immense volume of data traffic. By employing 2.5D and 3D IC architectures through heterogeneous integration, we can greatly enhance energy efficiency and reduce latency in data transfers. A key component of this advancement is the automation of design and simulation for heterogeneous AI chips, where powerful algorithms take the lead, rather than humans. This remarkable capability hinges on advanced electronic design automation (EDA) tools. At Georgia Tech, my research team merges AI-driven and traditional algorithms to bolster EDA capabilities, specifically engineered for developing cutting-edge heterogeneous AI chips. In my talk, I will spotlight these innovations and address the ongoing challenges in AI chip design and EDA.

    Speaker: Dr. Ji-Xin Cheng, Ph.D., Moustakas Chair Professor in Photonics and Optoelectronics; Professor of Biomedical Engineering. Professor of Electrical & Computer EnProfessor of Chemistry & Professor of Physics Boston University

    Talk Title: Seeing the unseen using molecular fingerprints

    Abstract: Spectrochemical imaging, using intrinsic fingerprint spectroscopic signals from molecules as a contrast mechanism, opens a new window for understanding life at the molecular level and also enables molecule-based precision diagnosis of diseases. Yet, the intrinsic spectroscopic signal, especially the vibrational signals from chemical bonds, is weaker than the fluorescence signal from a dye by many orders of magnitude. Detecting such weak signal from a tight focus (i.e., a small volume of ~1 femtoliter) under a microscope is extremely challenging and was considered nearly impossible. Ji-Xin Cheng devoted his career to overcoming such daunting barrier through developing advanced chemical microscopes over the past 25 years. In this lecture, Cheng will tell his journey of serendipity-driven innovation, scientific discovery, clinical translation, and entrepreneurship in the growing field of chemical imaging.

    Biography: Ji-Xin Cheng attended University of Science and Technology of China (USTC) from 1989 to 1994. From 1994 to 1998, he carried out his PhD study on bond-selective chemistry at USTC. As a graduate student, he worked as a research assistant at Universite Paris-sud (France) on vibrational spectroscopy and the Hong Kong University of Science and Technology (HKUST) on quantum dynamics theory. After postdoctoral training on ultrafast spectroscopy at HKUST, he joined Sunney Xie’s group at Harvard University as a postdoc, where he spearheaded the development of CARS microscopy that allows high-speed vibrational imaging. Cheng joined Purdue University in 2003 as Assistant Professor in Weldon School of Biomedical Engineering and Department of Chemistry, promoted to Associate Professor in 2009 and Full Professor in 2013. He joined Boston University as the Inaugural Theodore Moustakas Chair Professor in Photonics and Optoelectronics in summer 2017.
     Among his honors, Cheng is the recipient of the 2024 Raman Innovation Award at the International Conference of Raman Spectroscopy (ICORS, Rome), the 2024 Analytical Chemistry Spectrochemical Analysis Award from American Chemical Society, the 2024 Charles Delisi Award from Boston University College of Engineering, the 2024 Biophotonics Technology Innovator Award from International Society for Optics and Photonics (SPIE), the 2022 Boston University Innovator of Year, the 2020 Pittsburgh Spectroscopy Award from the Spectroscopy Society of Pittsburgh, the 2019 Ellis R. Lippincott Award from Optica, Society for Applied Spectroscopy, and Coblentz Society, the 2016 Research Award from Purdue University College of Engineering, and the 2015 Craver Award from Coblentz Society.

    Aerospace and Mechanical Engineering

    Conferences, Lectures, & Seminars


    Speaker: Andres Jared Goza, University of Illinois Urbana-Champaign

    Talk Title: Lighting the fuse to enable metamaterials for passive, adaptive flow control

    Abstract: Unsteady flow control is challenging in many engineering domains. Active techniques are costly, energy-intensive, and heavy, while passive approaches often lack robustness in handling complex flow dynamics. Metamaterials are structures with engineered architecture, allowing for catered response behaviors to stimuli. These structures offer a transformative potential for flow control by flow-metamaterial interaction, FMI. FMI could allow engineers to leverage architected structures to passively and adaptively produce desired flow responses. 
     
    To capitalize on this potential, however, we must first identify which classes of metamaterials are most promising for different flow scenarios, and understand how to align the key metamaterial behaviors with the relevant flow length- and timescales to enable favorable flow-structure interplay.  This understanding must account for the behavior of the fully coupled flow-metamaterial system, which will generally yield dynamics with distinct time/length scales from those of the constituent flow/structure systems. Obtaining this understanding requires a suite of computational tools capable of predicting and understanding the flow-structure interplay between the targeted complex flows and modern architected structures.

     
    We present some a-la-carte results on these various challenges and opportunities. We discuss some key metamaterial classes promising for certain flow behaviors. We share some ongoing development of high-fidelity and resolvent computational tools within an immersed boundary framework, currently without flow-structure interplay but being designed to enable robust, versatile computations between flows and a wide range of metamaterials. Finally, for simplified flow-metamaterial configurations, we discuss efforts to synthesize appropriate dimensionless parameters, expressed in terms of key intrinsic properties of the separate flow/structure systems, that govern the FMI system's behavior.  

     
     
    *Andres is grateful for funding from AFOSR to perform the presented work.
     

    Biography:  Andres is an Assistant Professor at UIUC. He uses computational techniques to study flow-structure interaction, particularly when the structure has some heterogeneous properties that make the coupled behavior more complex. He is interested in developing high-fidelity and analysis techniques to simulate and understand these dynamics. He also has two young children that bring fun regular surprises, and enjoys running, cycling, squash, and bouldering.

    Speaker: Sanjay Kumar, M.D, Ph.D., Chancellor Professor and Director of the California Institute for Quantitative Biosciences at UC Berkeley (QB3-Berkeley

    Talk Title: Tales from the fourth dimension: Incorporating the element of time into biomaterial paradigms

    Abstract: It is increasingly accepted that cell and extracellular matrix structure and mechanics can drive biology and disease, influencing everything from metabolism to stem cell differentiation to tumor progression.   While  significant progress has been made in developing culture technologies that mimic the complex physical microenvironment of tissue, many of these platforms are comparatively static in nature.   There remains a need to understand how cell-matrix dynamics influence cell behavior.  For example, how do cells remodel the carefully constructed matrices in which we place them, and how does this remodeling drive the biology we observe?  And how does the time-dependent dissipation of cell-imposed stresses influence force-based signaling?  While the answers are far from clear, I will describe efforts our team has made to attack these challenging problems, ranging from the use of proteomics to characterize the matrisome of invasive tumor cells ensconced within 3D matrices to to development and application of viscoelastic matrices to probe effects of stress relaxation on stem cell lineage commitment.    

    Biography: Sanjay Kumar, M.D., Ph.D., is Chancellor Professor and Director of the California Institute for Quantitative Biosciences at UC Berkeley (QB3-Berkeley).  His primary appointment is in the Department of Bioengineering (which he chaired from 2019-22), with joint appointments in the UC Berkeley Department of Chemical and Biomolecular Engineering, the UCSF Department of Bioengineering and Therapeutic Sciences, and Lawrence Berkeley National Laboratory.  Dr. Kumar earned his B.S. in Chemical Engineering at the University of Minnesota (1996) and his M.D. and Ph.D. in Molecular Biophysics from Johns Hopkins University (2003).  He then completed postdoctoral training at Boston Children’s Hospital and Harvard Medical School.   Dr. Kumar has co-authored >100 peer-reviewed publications and mentored >30 graduate students and postdoctoral fellows.  He and his group have been recognized with the Presidential Early Career Award for Scientists and Engineers (PECASE), The NIH Director’s New Innovator Award, The Beckman Young Investigator Award, the NSF CAREER Award, and the Stem Cells Young Investigator Award.

    Speaker: Laurent Lessard, Associate Professor, Mechanical and Industrial Engineering } Northeastern University

    Talk Title: An automatic system to detect equivalence between iterative algorithms

    Series: CSC/CommNetS-MHI Seminar Series

    Abstract: Large-scale optimization problems in machine learning, signal processing, multi-agent systems, and imaging have fueled ongoing interest in iterative optimization algorithms. New optimization algorithms are regularly proposed in order to capture more complicated models, reduce computational burdens, or obtain stronger performance and convergence guarantees. But how can we be sure a recently proposed algorithm is novel? Algorithms can be written in different equivalent ways that are not always obvious, and with optimization being increasingly prevalent across different applications, popular algorithms are routinely "re-discovered". In this talk, we present a framework for reasoning about equivalence of iterative algorithms. Our framework is based on concepts from control theory and linear systems theory and can identify equivalence for a variety of algorithm classes: (a) single-oracle algorithms such as gradient-based methods, (b) multi-oracle algorithms such as distributed optimization algorithms, primal-dual methods, and operator-splitting methods, and (c) algorithms that use different but related oracles, such as subdifferentials, proximal operators, and Fenchel conjugates. Our work is a promising step towards an integrated and principled methodology for analyzing and designing control systems that use optimization algorithms "in the loop". 

    Biography: Laurent Lessard is an Associate Professor of Mechanical and Industrial Engineering at Northeastern University, Boston, USA, and a core faculty member of the Experiential Institute for AI. He received a B.A.Sc. in Engineering Science from the University of Toronto, and the M.S. and Ph.D. in Aeronautics and Astronautics at Stanford University. His research interests include: decentralized control, robust control, optimization, and machine learning. Before joining Northeastern, he was a Charles Ringrose Assistant Professor of Electrical and Computer Engineering at the University of Wisconsin–Madison. Prior to that, he was an LCCC Postdoc in the Department of Automatic Control at Lund University, Sweden, and a postdoctoral researcher in the Berkeley Center for Control and Identification at the University of California, Berkeley. Laurent is a recipient of the Hugo Schuck best paper award and the NSF CAREER award. He is also a Senior Member of IEEE.

    Talk Title: More legs are different: the surprising simplicity of multi-legged locomotion

    Series: EE598 Seminar Series

    Abstract: Most of the animals that move with legs in the world do so with six or more legs, yet humans have focused primarily on bipeds and quadrupeds in designing legged robots. This talk will present some theoretical and experimental results that suggest that multi-legged robots with six or more legs exhibit some surprising properties that challenge our anthropocentric intuitions about locomotion. Modeling multi-legged motion fairly accurately, at single percentage points of relative error, turns out to be much easier than naively expected. This is both due to event-selected hybrid systems resolving multi-contact collisions in a smooth way, and due to the surprisingly high accuracy of geometric mechanics models on dry friction problems to which they shouldn't really apply. Together our results suggest that modeling and learning how to move with many legs might be much easier than has previously been thought.

    Biography: Shai Revzen is an Associate Professor of Electrical Engineering and Computer Science in the University of Michigan's College of Engineering, and holds a courtesy faculty appointment in the Department of Ecology and Evolutionary Biology. He received his PhD in Integrative Biology doing research in the PolyPEDAL Lab at the University of California at Berkeley, and did his postdoctoral work in the GRASP Laboratory of the University of Pennsylvania. Prior to his academic work, Shai spent a decade in the tech industry, rising to Chief Architect R&D of the convergent systems division of Harmonic Lightwaves (HLIT). He is currently co-founder and Chief Science Officer of Acculine Medical, and General Manager of his consulting company, Izun, Inc. In his spare time he does martial arts and studies for a JD Law degree at Wayne State University.

    Speaker: Rahul Panat, Carnegie Mellon University

    Talk Title: Printed 3D Microelectronics: Process Development, Materials Science, and Devices Applications

    Abstract: In this research, we develop a printed microelectronics technique based on droplet-based nanoparticle printing using the Aerosol Jet (AJ) technology. A balance between inertia forces and surface forces for the microdroplets (each containing nanoparticles), along with rapid solvent evaporation are used to create highly complex 3D microarchitectures of metals and polymers without auxiliary support and with near-fully dense truss members. Highly intricate 3-D micro-lattices, pillars, interconnects, and spirals are demonstrated.   We then use these structures to: (i) study fundamental material science, and (ii) demonstrate device applications with extraordinary performance that cannot be achieved by any other method. For (i), a temperature-gradient-driven mass transport is shown as a new mechanism of 4D printing. For (ii), novel 3D geometry of electrodes enables detection of pathogen antibodies and antigens in 10-12 seconds at femtomolar sensitivities - the fastest detection of disease biomarkers yet reported! This technology is validated through human trials. In addition, the 3D microarchitectures in our lab enable fully customizable brain-computer interfaces (BCIs) that record electrical signals between neurons at densities of thousands of electrodes/cm2, which is 5-10× the current state-of-the-art BCI technologies. The technology was validated through animal testing via recording of the action potentials from the mouse brain. We also demonstrated the printing of high-capacity Li-ion batteries and thin flexible robotic skins with embedded sensors. Lastly, our ongoing work on creating manufacturing digital twins of the AJ printing process is also discussed.

    Biography: Prof. Panat is Professor. He is courtesy faculty in the Materials Science and Engineering and the Robotics Institute at CMU. He is also the Associate Director of Research at the Manufacturing Futures Institute at CMU, which is focused on bringing the latest advances in digital technologies to advanced manufacturing.

    Talk Title: Virtual Power Plant Control for Dynamic Ancillary Services Provision

    Series: CSC/CommNetS-MHI Seminar Series

    Abstract: This presentation focuses on innovative control strategies for dynamic virtual power plants (DVPPs) aimed at providing dynamic ancillary services efficiently. The first part highlights the importance of heterogeneity among distributed energy resources in reliably delivering services like fast frequency and voltage control across various power and energy levels. A "divide-and-conquer" approach, along with dynamic participation factors and local matching controllers, is proposed. The second part introduces a closed-loop strategy incorporating data-driven techniques to adapt ancillary services to local grid conditions. Structural encoding of dynamic ancillary services and a "perceive-and-optimize" strategy ensure stable and optimal performance while meeting grid-code and device-level requirements. Numerical case studies and hardware experiments validate the effectiveness of these approaches, promising improved grid stability and efficiency.

  • Modeling Human Motion Behaviors and 3D Environment from Real-World Capture

    Tue, Oct 15, 2024 @ 04:00 PM - 05:00 PM

    Thomas Lord Department of Computer Science

    Conferences, Lectures, & Seminars


    Speaker: Andrew Feng , Associate Director - Geospatial Research, USC-ICT

    Talk Title: Modeling Human Motion Behaviors and 3D Environment from Real-World Capture

    Abstract: Synthesizing believable human motions based on input conditions is an essential task that will find many applications in gaming, simulation, and virtual reality. Various conditional inputs can be utilized to drive the motion synthesis process such as speech, music, action categories, and natural language text descriptions. Generating motions from text prompts or speech audios requires modeling of both languages and motions, which is especially challenging as the model needs to learn a cross-modal mapping to produce motion sequences. Another challenge in learning the motion synthesis model is that the cross-modal mapping may not be deterministic. For instance, there may be multiple viable gesture motions for the same speech utterance that are all plausible. The first part of this talk will cover our research in leveraging discrete latent space learning and recent generative modeling methods to address such challenges. Our proposed method models the motion segments as discrete codes and learns the underlying data distributions for these motion units. Therefore it does not suffer from the over-smoothed or damped animations caused by the deterministic mapping of the regression models in previous methods.   Modeling the real world environment from multi-view images remain significant challenges in computer vision and graphics. The resulting models need to retain both accurate visual appearances and geometry to be valuable for digital twins, simulation, or scan-to-BIM applications. 3D Gaussian Splatting (3DGS) has recently advanced the field to be a viable method for novel view synthesis and real-time rendering. The second part of the talk will cover our recent research work in 3DGS for revising the training and densification strategy to improve the radiance field and geometry reconstructions.      
     
    This lecture satisfies requirements for CSCI 591: Research Colloquium.

    Talk Title: Fluid Structural Thermal Interaction (FSTI) in Hypersonic Flow

    Abstract: When flowing fluids and deformable structures interact, they may become unstable (flutter) and if the system is nonlinear this may lead to limit cycle oscillations and even chaotic dynamics. Physical phenomena of interest include wind induced oscillations of long span bridges and tall buildings, internal flows in nuclear reactors and gas turbines, blood flow through arteries and airflow over human tongues. However historically and even today much of the progress is driven by aerospace applications including high performance flight vehicles be they aircraft, jet engines, launch vehicles, missiles or rotorcraft.  Current interest in FSTI in hypersonic flow is high and will be the subject of this talk. Both experimental and theoretical (computational) work will be discussed.

    Talk Title: Jailbreaking LLM-Controlled Robots

    Series: EE598 Seminar Series

    Abstract: Recent research has shown that large language models (LLMs) such as OpenAI's ChatGPT are susceptible to jailbreaking attacks, wherein malicious users fool an LLM into generating harmful content (e.g., bombbuilding instructions). However, these attacks are generally limited to eliciting text from chatbots. In contrast, we consider attacks on LLM-controlled robots, which, if jailbroken, could be manipulated into causing physical harm in the real world. Our attacks successfully jailbreak a self-driving LLM, a wheeled Clearpath Robotics Jackal robot, and, most concerningly, the commercially available Unitree Go2 robot dog. In this talk, we will walk through the recent history of jailbreaking, describe our robotic attacks, and discuss how such attacks can be mitigated to avoid the misuse of AI-powered robots.

    Biography: Alex Robey is a postdoctoral researcher in the Machine Learning Department at Carnegie Mellon University, where he is advised by J. Zico Kolter. He is also affiliated with Gray Swan, a start-up that aims to develop AI models resistant to adversarial attacks. In 2024, he received his Ph.D. from the Department of Electrical and Systems Engineering at the University of Pennsylvania, where he was advised by Hamed Hassani and George J. Pappas. He was recently named a Rising Star in Adversarial Machine Learning (AdvML) at the NeurIPS 2024 workshop on AdvML, and he was also the recipient of the Best Paper Award from the AdvML workshop at ICML 2023.

    Speaker: Ananya Balakrishna, UC Santa Barbara

    Talk Title: Phase Transformations in Multifunctional Materials

    Abstract: Phase transformation materials are characterized by their ability to rapidly and reversibly switch between distinct properties, such as insulating and conducting, paramagnetic and ferromagnetic, or Li-rich and Li-poor. These transformations, however, are accompanied by abrupt structural changes in the crystal lattices, which can nucleate defects, accumulate strain energy, and accelerate material decay. We investigate these transformations in multifunctional materials from the viewpoint of Ericksen’s multiple energy wells. By doing so, we identify important links between material constants, crystallographic microstructures, and macroscopic properties. This approach to understanding material behavior from the perspective of energy landscapes may suggest new ways to design materials with improved properties and lifespans. In this talk, I will present our findings on phase transformations in battery electrodes (intercalation compounds), photomechanical materials (molecular crystals), and soft magnetic alloys. Most of this work has primarily been conducted by Delin Zhang (PhD candidate at USC/AME) and Devesh Tiwari (MS from USC/AME).

    Biography: Ananya Renuka Balakrishna is an Assistant Professor in the Materials Department at the University of California Santa Barbara. She received her B.Tech degree in Mechanical Engineering from the National Institute of Technology Karnataka and her Ph.D. in Solid Mechanics and Materials Engineering from the University of Oxford. Before her current appointment, she was a Lindemann Postdoctoral Fellow at MIT and the University of Minnesota and joined the faculty in the Department of Aerospace & Mechanical Engineering at the University of Southern California in 2020. Her research group develops theoretical models to understand the interplay between fundamental material constants and microstructural instabilities, and how they collectively shape the physical response of a material.

    Talk Title: From neurological disorders to additive manufacturing: integrating isogeometric analysis with deep learning and digital twins

    Abstract: Coupling physics-based simulation and data-driven modeling have demonstrated great power in predicting complex systems. This talk focuses on integrating an advanced finite element method called isogeometric analysis (IGA) with deep learning and digital twins to address challenging problems in investigating neurological disorders and additive manufacturing (AM). To investigate neurodevelopmental disorders, we introduce a novel phase field model coupled with tubulin and synaptogenesis concentration to simulate intricate neurite outgrowth and disorders using IGA, dynamic domain expansion and local refinement. By integrating IGA and convolutional neural networks, we conduct thorough investigations into the functional role of various parameters affecting the neurodevelopmental disorder with comparison to experimental results. To investigate intracellular transport induced neurodegenerative disorders, we develop a PDE-constrained optimization model to simulate traffic jams induced by microtubule reduction and swirl. We also build a novel IGA-based physics-informed graph neural network to quickly predict normal and abnormal transport phenomena in complex neuron geometries.
     
    In the second half of the talk, I will present our latest research on generative manufacturing or combining AI with IGA for AM applications. It includes a machine learning framework for inverse design and manufacturing of self-assembling fiber-reinforced composites in 4D printing, IGA-based topology optimization for AM of heat exchangers, as well as data-driven residual deformation prediction to enhance metal component printability and lattice support structure design in the laser powder bed fusion (LPBF) AM process. By speeding up geometry distortion predictions from several hours to mere seconds with uncertainty quantification, our model can be deployed to prevent generation of infeasible designs. Our on-going efforts also include developing digital twins to enable prediction and control of process parameters in LPBF manufacturing, where reduced order modeling is one key technique to efficiently simulate underlying physics.

    Talk Title: Diagnosing disease on a microchip: Finding nanoscale needles in messy nanoscale haystacks

    Abstract: The transformative growth in microelectronics in the latter half of the 20th century was fueled fundamentally by the ability to miniaturize complex circuits onto chips. The impact of this has been profound– computing is pervasive and portable and communication is instant and global. My research aims to harness this same engineering approach to solve high impact problems in medical diagnostics. To accomplish this goal my lab develops hybrid microchips, where microfluidics are built directly on top of semiconductor chips. In this talk I will focus on recent work at Penn on 'digital asays.' Digital assays — in which ultra-sensitive molecular measurements are made by performing millions of parallel experiments in picoliter droplets — have generated enormous enthusiasm due to their single molecule resolution. These assays have incredible untapped potential for disease diagnostics but are currently confined to laboratory settings due to the instrumentation necessary to generate, control, and measure tens of millions of droplets. To overcome this challenge, we are developing a hybrid microelectronic / microfluidic chip to ‘unlock’ droplet-based assays for mobile use. Our microDroplet Megascale Detector (µMD) takes inspiration from cellular networks, in which phones are identified by their carrier frequency and not their particular location.  In collaboration with physicians at The Abramson Cancer Center, we are demonstrating the power of this approach by developing a multiplexed extracellular vesicle-based diagnostic for the early detection of pancreatic cancer. I will also discuss ongoing projects on the early diagnosis of lung cancer, treatment guidance for traumatic brain injury, and the differential diagnosis of Alzheimer's versus Lewy body dementia.

    Biography: The Issadore lab combines microelectronics, microfluidics, nanomaterials, and machine learning to solve big problems in healthcare. We create miniaturized platforms for the diagnosis of disease, we develop new platforms to manufacture micro and nanomaterials, and we dip our toes into an assortment of other areas where we can leverage our engineering training to improve healthcare. This work requires an interdisciplinary approach in which engineers, scientists, and physicians work together in teams. David received his PhD in applied physics from Harvard and his BS in both electrical engineering and physics from Penn State. Before coming to Penn, where he is now a Professor of Bioengineering, he was a postdoctoral fellow at MGH's Department of Systems Biology.

    Talk Title: Why Are Human Laws So Difficult For AI to Follow?

    Abstract: Join Zoom Meeting: https://usc.zoom.us/j/96076927864?pwd=tOuC1grLlyiRgcwicpm9e7XziHgE0R.1 Meeting ID: 960 7692 7864 Passcode: 810249 Register in advance for this webinar:  https://usc.zoom.us/webinar/register/WN_ANEShGxrSfeTwa5sFZsRag Although it is now incredibly easy to create and deploy a chatbot for almost any application, powered by highly capable LLMs, even the best systems still tend to perform poorly when they need to interpret and reason about rules---specifically, rules expressed in the kind of language found in laws, contracts, regulations, and the like. Why does this problem still exist, and how can it be overcome? Dr. Licato argues that the problem is rooted in a feature (not a bug) of human languages called open-texturedness. And this open-texturedness, because it is an inevitable feature of normative rule systems, must be addressed by any agent-level AI system, especially if we want it to be able to follow our laws.

    Talk Title: Data-Driven Approaches for Estimating Reachable Sets in Complex Dynamical Systems

    Series: CSC/CommNetS-MHI Seminar Series

    Abstract: The computation of reachable sets is essential for characterizing and verifying the behavior of safety-critical systems. However, many practical systems are high-dimensional and analytically intractable, making the exact computation of reachable sets difficult or impossible. We propose a data-driven approach that uses a finite ensemble of sample trajectories to estimate reachable sets with probabilistic accuracy guarantees. This method is broadly applicable and computationally advantageous, as the main cost comes from simulating a predetermined number of trajectories, which can be parallelized to reduce computation time. We first present a method that uses scenario optimization to construct reachable set estimates as approximate solutions to chance-constrained optimization problems. Next, we use a class of polynomials derived from empirical moment matrices, whose sublevel sets act as nonconvex estimates of the reachable set. These data-driven methods offer scalable solutions for estimating reachable sets in systems with complex dynamics.

    USC School of Advanced Computing

    Conferences, Lectures, & Seminars


    Speaker: Vikram Gavini, University of Michigan

    Talk Title: Large-scale electronic structure calculations of extended defects in materials

    Abstract: Defects play a crucial role in influencing the macroscopic properties of solids—examples include the role of dislocations in plastic deformation, dopants in semiconductor properties, and domain walls in ferroelectric properties. These defects are present in very small concentrations (few parts per million), yet, produce a significant macroscopic effect on the materials behavior through the long-ranged elastic and electrostatic fields they generate. Notably, the strength and nature of these fields, as well as other critical aspects of the defect-core are all determined by the electronic structure of the material at the quantum-mechanical length-scale. However, carefully converged electronic structure studies on extended defects, such as dislocations, have been out of reach due to the cell-size and periodicity limitations of the widely used electronic structure codes.
     
    This talk will discuss the recent developments that have enabled large-scale density functional theory (DFT) calculations, paving the way for electronic structure studies of defects. The first part of the talk will discuss the development of computational methods and numerical algorithms for conducting fast and accurate large-scale DFT calculations using adaptive finite-element discretization, which form the basis for the recently released DFT-FE open-source code. The second part of the talk will focus on electronic structure studies of dislocations using the developed methods and the insights obtained into fundamental questions such as: What is the core size of a dislocation? Are forces on dislocations solely from elastic interactions? Recent studies on using DFT-FE to understand the energetics of <c+a> dislocations in Mg, and the energetics and nucleation kinetics of quasicrystals (ScZn7.33) will be discussed

    Biography: Vikram Gavini is Professor of Mechanical Engineering and Materials Science & Engineering at the University of Michigan. He received his Ph.D. from California Institute of Technology in 2007. His interests are in developing methods for large-scale and quantum-accurate electronic structure calculations, numerical analysis of PDEs and scientific computing. DFT-FE, a massively parallel open-source code for large-scale real-space DFT calculations, has been developed in his group. He is the recipient of NSF CAREER Award in 2011, AFOSR Young Investigator Award in 2013, Humboldt Research Fellowship for Experienced Researchers (2012-14), USACM Gallagher Award in 2015, among others. He led the team that received the 2023 ACM Gordon Bell Prize in high performance computing.

    Speaker: Dr. Yanzhi Wang, Associate Professor and Faculty Fellow, Dept. of ECE, Northeastern University

    Talk Title: A plug-and-play acceleration framework for generative AI models on the edge

    Abstract: In the generative AI era, general users need to apply different base models, fine tuned checkpoints, and LoRAs. Also the data privacy and real-time requirement will favor on-device, local deployment of large-scale generative AI models. It is desirable to develop a "plug-and-play" framework such that users can download any generative AI model, click and run on their own device. This poses significant challenge to the current AI deployment frameworks, which are typically time-consuming and requires human expertise of hardware and code generation. We present our effort of OminiX, which is a first step towards unified library and acceleration of generative AI models across various hardware platforms. Integrating our unique front-end library and back-end instantaneous acceleration techniques, which will be open-source soon, we show capability of plug-and-play deployment and state-of-the-art acceleration of various generative AI models, starting from image generation, large language models, multi-model language models, speech generation and voice cloning, real-time chatting engine, real-time translation, video generation, real-time avatar, to name a few. This can be achieved on everyone's own platform.

    Biography: Yanzhi Wang is Associate Professor in the Department of Electrical and Computer Engineering at Northeastern University, a senior member of IEEE. His research interests focus on real-time and energy-efficient deep learning and artificial intelligence systems, especially on efficient large language models and large-scale generative AI systems.

    Speaker: Gavin Kerrigan, PhD Candidate - Department of Computer Science, UC Irvine

    Talk Title: Generative Models and the Transport of Measure

    Abstract: A key theme in contemporary generative modeling is the continuous transport of measure, in which a simple reference distribution is gradually transformed into the data distribution. Many recent models, including diffusions and flows, can be viewed through this unifying lens. In this talk, we will first explore some geometric tools for studying dynamics in the space of probability measures. We will then leverage these tools to design generative models, with a focus on applications to inverse problems and complex data structures such as function-valued data.

    Thomas Lord Department of Computer Science

    Conferences, Lectures, & Seminars


    Speaker: Dr. Juan Wachs , Professor & University Faculty Scholar, Industrial Engineering School - Purdue University

    Talk Title: The Algorithmic Abyss: Exploring Autonomy without Robotic Horror

    Abstract: Robots can already solve sophisticated problems ranging from playing games, autonomous driving, and dancing—given enough observational data for training. The core of such success resides in efficient algorithms, compliant hardware and robust computing, all implemented using carefully curated data collected before the training phase. Thus, robots learn in a “sterile” domain, under clean, controlled and to some extent supervised environments. As the target domain changes, however, moving to more quotidian scenarios, robots struggle to perform well. It is hard to think of an autonomous car trained in Silicon Valley being able to successfully navigate the crowded streets of New Delhi. – this is the “algorithm abyss”. Ideally, we would like to robots adapt to challenging settings while immersed in mundane settings, and learn from few observations. To address this hurdle, my work in the area of robotics and autonomous systems focuses on transferring skills and knowledge from controlled settings to the wild. In this talk, I emphasize strategies and techniques to address fundamental challenges in emergent, high-risk, high-stakes scenarios. Specifically, I will discuss work related to telesurgery, skill augmentation and bioinspired designs. While healthcare is one of the research domains discussed, the outcomes and findings are applicable to the range field of autonomous robotics. Progress in these directions will contribute to the public purpose of creating the knowledge for developing robots that are more accessible, effective and sensitive to social needs.

However, there is very little published experimental evidence to support such a claim. Here, we develop a set of synthetic impossible languages of differing complexity, each designed by systematically altering English data with unnatural word orders and grammar rules. These languages lie on an impossibility continuum: at one end are languages that are inherently impossible, such as random and irreversible shuffles of English words, and on the other, languages that may not be intuitively impossible but are often considered so in linguistics, particularly those with rules based on counting word positions. We report on a wide range of evaluations to assess the capacity of GPT-2 small models to learn these uncontroversially impossible languages, and crucially, we perform these assessments at various stages throughout training to compare the learning process for each language. Our core finding is that GPT-2 struggles to learn impossible languages when compared to English as a control, challenging the core claim. More importantly, we hope our approach opens up a productive line of inquiry in which different LLM architectures are tested on a variety of impossible languages in an effort to learn more about how LLMs can be used as tools for these cognitive and typological investigations.

    Biography: Julie Kallini is a second-year Computer Science Ph.D. student at Stanford University advised by Christopher Potts and Dan Jurafsky. Her research spans several topics in natural language processing, including computational linguistics, cognitive science, interpretability, and model architecture.

  • Program Analysis for Block-Based Learners Programs

    Speaker: Prof. Gordon Fraser, PhD, Computer Science Professor - University of Passau, Germany

    Talk Title: Program Analysis for Block-Based Learners Programs

    Abstract: Programming is increasingly taught using dedicated block-based programming environments such as Scratch. While the use of blocks instead of text prevents syntax errors, learners can still make semantic mistakes implying a need for feedback and help. While professional programmers receive this support from efficient program analyses built into their IDEs, block-based programming environments offer no such support. In this talk I will describe some of our efforts to remedy this issue, ranging from static source code linting, search-based testing, interrogative debugging, automated program repair, to neural program analysis. The colourful and small nature of learners’ programs is deceiving, as the game-like, highly concurrent and event-driven nature of the programs poses unique challenges for these analyses.

    Talk Title: Exploring Ways to Maximize Efficiency and Performance in Low-Dropout (LDO) Regulators

    Series: Integrated Systems

    Abstract: Low-dropout (LDO) regulators are ideal off- and on-chip solutions for powering noise-sensitive loads due to their ripple-less output. LDOs also have many benefits over switch-mode dc-dc converters, such as rapid transient response, excellent power supply rejection (PSR), and compact footprint. Unfortunately, they suffer from an inescapable disadvantage: poor power efficiency; this is primarily caused by a considerable dropout voltage (VDO). Reducing VDO to improve efficiency often leads to a significant drop in LDO's regulation performance. Because of this, most LDOs are designed with a large VDO, making them perceived as energy-consuming components of power management systems. This talk will delve into effective ways to extremely minimize the dropout voltage without compromising performance, aiming for energy-efficient LDO regulators. We will begin with a thorough investigation of operational principles, analyses, and strategies, exploring trade-offs among key performance metrics. Next, several promising approaches to realizing energy-efficient LDO regulators will be investigated, including traditional digital LDOs, a dual-rail analog/digital-hybrid LDO, a triode-region LDO, and a voltage/current-hybrid (VIH) LDO. Finally, the technical merits and flaws of each high-efficiency LDO topology will be investigated by comparing them. In this talk, I will also share my insights from my experience developing the VIH LDO regulator that achieves 98.6% efficiency and a -75dB PSR at 30kHz.

    Speaker: Dr. Jorge Cortes, Professor and Cymer Corporation Endowed Chair in High Performance Dynamic Systems Modeling and Control | Department of Mechanical and Aerospace Engineering, University of California, San Diego

    Talk Title: The safe gradient flow: a system-theoretic approach to anytime constrained optimization through control barrier functions

    Series: CSC/CommNetS-MHI Seminar Series

    Abstract: Problems where the solution to a constrained optimization problem is used to regulate a physical process modeled as a dynamically evolving plant arise in multiple application areas, including safety-critical control, power networks, traffic networks, and network congestion. This may take the form of providing setpoints, specifying optimization-based controllers, or steering the system toward an optimal steady state.  A paradigmatic example is the use of CBF-based quadratic programs for controller synthesis in robotics.  In this talk, we are motivated by situations where the problem incorporates constraints which, when violated, threaten the safe operation of the physical system.  In such cases, the algorithm that solves the optimization must be anytime, meaning that it is guaranteed to return a feasible point even when terminated before it has converged to a solution.  We introduce a class of novel system-theoretic algorithms for solving constrained nonlinear programs that combine continuous-time gradient flows to optimize the objective function with techniques from control barrier functions to maintain forward invariance of the feasible set. We refer to the resulting closed-loop system as the safe gradient flow.  We draw on the alternative interpretation of the safe gradient flow as a projected dynamical system to characterize its dynamical properties regarding regularity, stability, convergence, contractivity, and invariance.  We also show how the proposed framework is conducive to the extension of the proposed designs to monotone variational inequalities and discrete-time settings.

    Speaker: Prof. Stefano Maci, IEEE AP-S Past President, University of Sienna, Italy

    Talk Title: Metasurface Antennas

    Series: IEEE GRSS-APS-SSCS

    Abstract: Metasurfaces belong to the category of thin metamaterials and find applications across a wide frequency range, from microwaves to optical frequencies, for developing innovative electromagnetic engineering devices. These surfaces are created by densely arranging small elements on or etching them into a dielectric substrate in a locally periodic distribution. By adjusting the dimensions of these elements while maintaining sub-wavelength 2D periodicity, a pixelated visual appearance and an electromagnetic modulation of the equivalent local impedance boundary conditions (IBC) are achieved.  The manipulation of IBC allows for localized modifications in the dispersion equation, influencing the local wavevector while maintaining a constant operating frequency. This capability enables the transformation of surface or guided waves into various wavefield configurations with specified properties. This presentation will focus on the control of both surface waves and space waves, showcasing examples such as the design of high-gain, low cross-polarization antennas, multibeam antennas, and scanning beam flat lenses. Emphasis will be given to space applications.  The discussion will also delve into the third generation of adaptive metasurfaces (MTSs), featuring dynamically reconfigurable boundary conditions. This advancement opens possibilities for exploring new perspectives in the development of next-generation wireless communication systems.

    Speaker: Dr. Tim Althoff, Assistant Professor, Allen School of Computer Science - University of Washington

    Talk Title: Language Models as Temporary Training Wheels to Improve Mental Health

    Abstract: Access to mental health care falls short of meeting the significant need. More than one billion individuals are affected by mental health conditions, with the majority not receiving the necessary treatment.   In this talk, I will describe how human-AI collaboration, critically enabled by language models, can improve access to and quality of mental health support. Language models have the potential to act as temporary training wheels providing immediate support and guidance to help individuals develop essential mental health skills. This approach emphasizes the importance of using these tools as initial aids rather than long-term crutches. By offering structured assistance, practice, and feedback, language models can help individuals and professionals learn skills, such as cognitive reframing, emotional regulation, and conflict resolution. However, the ultimate goal is for individuals to gradually transition away from dependence on these models, fostering sustained skill development and long-term well-being. This talk will describe how language models can be developed towards these aims and evaluate their effectiveness across multiple randomized trials and real-world deployments with over 150,000 participants.

    Talk Title: Perceive with Confidence: Statistical Safety Assurances for Vision-based Navigation

    Series: EE598 Seminar Series

    Abstract: Significant strides in perception over the past few years have enabled robotic systems to interpret and interact with the world in increasingly versatile ways. The large, often multi-modal, datasets that are used to train modern perception systems endow robots with capabilities for scene understanding like object detection and segmentation. However, the safe integration and reliability of these learned perception models for robotic applications still remains in question due to their failures in unfamiliar environments. In this talk, I will discuss our framework, Perceive with Confidence (PwC), for rigorously quantifying the uncertainty of a pre-trained obstacle detection system in a way that provides a formal assurance on correctness and safety for planning applications. This is achieved by utilizing a technique called conformal prediction to calibrate the perceptual outputs while ensuring generalization to novel environments. I will provide experimental validations of PwC’s formal assurances for indoor navigation applications on the Unitree Go1 quadruped.

However, most studies focus on simplistic and static self-report or performance-based tests, which limits the depth and validity of the analysis. In this paper, we developed a novel framework, INTERINTENT, to assess LLMs’ social intelligence by mapping their ability to understand and manage intentions in a game setting. We focus on four dimensions of social intelligence: situational awareness, self-regulation, self-awareness, and theory of mind. Each dimension is linked to a specific game task: intention selection, intention following, intention summarization, and intention guessing. Our findings indicate that while LLMs exhibit high proficiency in selecting intentions, achieving an accuracy of 88%, their ability to infer the intentions of others is significantly weaker, trailing human performance by 20%. Additionally, game performance correlates with intention understanding, highlighting the importance of the four components towards success in this game. These findings underline the crucial role of intention understanding in evaluating LLMs’ social intelligence and highlight the potential of using social deduction games as a complex testbed to enhance LLM evaluation. INTERINTENT contributes a structured approach to bridging the evaluation gap in social intelligence within multiplayer games.

Previously, she earned her master’s degree at USC and was a Research Assistant in USC ISI’s Ink Lab for two years under the guidance of Professor Xiang Ren.  Her research focuses on social intelligence and hallucination detection in human-LLM interactions, particularly in evaluating LLM behaviors and aligning LLM values with those of humans. Her work is driven by two key questions: (1) How can we make interactions between models and humans more seamless? (2) How can we ensure the faithfulness of LLMs and avoid hallucinations during interactions?

    Speaker: Dr. Berivan Isik, Research Scientist, Google, Inc.

    Talk Title: Value of Pretraining Data: Scaling Laws for Downstream Task Performance of Large Language Models

    Abstract: This talk explores the challenges and open questions surrounding the value of pretraining data for large language models (LLMs) in transfer learning settings. While scaling laws have provided valuable insights for LLM design, existing work has predominantly focused on pretraining loss. In contrast, this work investigates scaling behavior in a transfer learning setting where LLMs are finetuned for downstream tasks. Specifically, we examine how the choice and size of pretraining data impact downstream performance, as measured by cross-entropy and translation quality metrics such as BLEU and COMET. Our experiments reveal that the size of the finetuning dataset and the alignment between pretraining and downstream data significantly influence scaling behavior. With sufficient alignment, both cross-entropy and translation quality improve with increased pretraining data, and we demonstrate the ability to predict translation quality using a new log-law. However, in cases of moderate misalignment, we observe that translation quality can fluctuate or even deteriorate with more pretraining data, despite consistent improvements in cross-entropy. Through analysis of these findings, we provide insights for selecting appropriate pretraining data. The talk will conclude with a discussion of future research directions and remaining open questions in this area.  

    Biography: Berivan Isik is a research scientist at Google, working on efficient and trustworthy AI. Her current interests are efficient training/finetuning of large models, pretraining data valuation and scaling laws for LLMs, differential privacy, and unlearning. She earned her PhD from Stanford University in 2024, where she was affiliated with the SAIL and StatsML groups. Her research was supported by Stanford Graduate Fellowship (2019-2023), Google Ph.D. Fellowship (2023-2026), and a Meta research grant.
