Fri, Nov 01, 2024 @ 11:00 AM - 12:00 PM
Alfred E. Mann Department of Biomedical Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. Remo Rohs, Ph.D., Professor of Quantitative and Computational Biology, Chemistry, Physics and Astronomy and Computer Science, University of Southern California
Talk Title: Engineering+: AI-driven discovery in biology
Abstract: In recent years, research in biology has become increasingly quantitative. This trend is due to two major drivers: Biology now generates large amounts of data in every experiment, and the power of computers has grown exponentially. The combination of data and computing is the basis of biological discovery in the 21st century. This talk will introduce AI-based and other computational methods developed in the Rohs lab with the goal to answer important biological questions related to gene regulation, nucleic acid structure, protein-nucleic acid binding, and drug design. These computational approaches combine biophysics, mathematics, and statistical machine learning. They enable, for instance, the probing a protein for its preference to bind either DNA or RNA or allow for the design of novel drug-like molecules that are not available in current drug libraries. Feature engineering is a crucial factor for the interpretability of these models. The talk will provide a vision for the crucial role of computational biology at the interface of engineering, medicine, and science.

Talk Title: Non-Hermitian quantum dynamics: super quantum correlations and breaking the quantum speed limit
Series: MHI Physics Joint Seminar Series
Abstract: Quantum theory provides rules governing much of the microscopic world. It dictates unitarity for isolated systems that when coupled to an environment, undergo decoherence. Among its counter-intuitive consequences are temporal (Leggett-Garg) correlations that exceed the bounds from local, classical theories. In the simplest system - a single qubit - LG correlations are bounded below 1.5 for unitary and decohering dynamics, with excess over 1 indicating "quantumness". Fundamentally, these bounds arise due to limits on the speed at which a quantum state can evolve into an orthogonal one. In recent years, quantum systems undergoing coherent but non-unitary evolution have emerged. They are governed by non-Hermitian, parity-time (PT) symmetric Hamiltonians with exceptional point degeneracies. After a short review of such systems, I will present results for PT-symmetry breaking, temporal correlations that exceed the LG bound of 1.5, and quantum state-transfers that exceed the quantum speed limit in a single trapped ion (arXiv:2304.12413, PRA 108, 032202 (2023)).*Work done with David Allcock group (University of Oregon) and Sourin Das group (IISER, Kolkata).
Biography: Yogesh Joglekar is an experimentally-minded theoretical physicist. After initial training and some time in condensed matter physics, he started moonlighting in the area of PT symmetry with the help of high-school students. They have helped him see how PT symmetry emerges in disparate platforms such as a single LC circuit or a vibrating tank of water. His primary area of research is open classical and quantum systems. He usually has far more questions than answers.

Talk Title: Foundational AI Framework for Automated Synthesis of Analog Integrated Circuits
Series: Integrated Systems
Abstract: Artificial intelligence (AI) and machine learning (ML) technologies have profoundly reshaped our world, manifesting their prowess in perception, knowledge generation, and decision making. In a similar fashion, AI/ML will undoubtedly be a disruptive force to revolutionize the IC design process. Due to their labor-intensive nature, analog and radio frequency (RF) circuits take a disproportionate share in design cost and could therefore benefit tremendously from automation. In this talk, I will present the recent work from my lab towards the goal of building a foundational AI framework for analog IC design automation. I will first introduce our deep learning-based method to automate parameter optimization in analog/RF circuits with a unique domain knowledge-infused approach. This method is then expanded to provide robustness and sampling efficiency against design variations caused by process, voltage, and temperature (PVT). Next, I will briefly talk about CktGNN, our hierarchical graph neural network-based approach to synthesizing circuit topology and the first of its kind that leads to the construction of an open-sourced analog circuit dataset (https://github.com/zehao-dong/CktGNN). Finally, I will conclude the talk with a vision statement and roadmap for future AI-driven design automation.

CSC/CommNetS-MHI Seminar: Negar Mehr
Mon, Nov 04, 2024 @ 02:00 PM - 03:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. Negar Mehr, Associate Professor, Department of Mechanical Engineering | UC Berkeley
Talk Title: Interactive Autonomy: Game-Theoretic Learning and Control for Multi-Agent Interactions
Series: CSC/CommNetS-MHI Seminar Series
Abstract: To transform our lives, autonomous systems need to interact with other agents in complex shared environments. For example, autonomous cars need to interact with pedestrians, human-driven cars, and other autonomous cars. Autonomous delivery drones need to navigate in the aerial space shared by other drones, or mobile robots in a warehouse must navigate in the factory space shared by robots. The multi-agent nature of such application domains requires us to develop a systematic methodology for enabling efficient interactions of autonomous systems across various applications. In this talk, I will first focus on game-theoretic planning and control for robots. To reach intelligent robotic interactions, robots must account for the dependence of agents' decisions upon one another. I will discuss how game-theoretic planning and control enables robots to be cognizant of their influence on other agents. I will present our recent results on leveraging the structure that is inherent in interactions to develop efficient motion planning algorithms which are suitable for real-time operation on robot hardware. In the second part of the talk, I will focus on how robots can learn and infer the intentions of their surrounding agents to account for agents' preferences and objectives. Currently, robots can infer the objectives of isolated agents within the formalism of inverse reinforcement learning; however, in multi-agent domains, agents are not isolated, and the decisions of all agents are mutually coupled. I will discuss a mathematical theory and numerical algorithms for inferring these interrelated preferences from observations of agents’ interactions.

Shifting the Frame: The Labors of ImageNet and AI Data
Wed, Nov 06, 2024 @ 02:00 PM - 03:00 PM
Thomas Lord Department of Computer Science
Conferences, Lectures, & Seminars
Speaker: Dr. Alex Hanna, Director of Research, Distributed AI Research Institute (DAIR)
Talk Title: Shifting the Frame: The Labors of ImageNet and AI Data
Abstract: Artificial intelligence (AI) technologies like ChatGPT, Stable Diffusion, and LaMDA have led a multi-billion dollar industry in generative AI, and a potentially much larger industry in AI more generally. However, these technologies would not exist were it not for the immense amount of data mined to make them run, low-paid and exploited annotation labor required for labeling and content moderation, and questionable arrangements around consent to use these data. Although datasets used to train and evaluate commercial models are often obscured from view under the shroud of trade secrecy, we can learn a great deal about these systems by interrogating certain publicly available datasets which are considered foundational in academic AI research.
In this talk, I investigate a single dataset, ImageNet. It is not an understatement to say that without ImageNet, we may not have the current wave of deep learning techniques which power nearly all modern AI technologies. I begin from three vantage points: the histories of ImageNet from the perspective of its curators and its linguistic predecessor WordNet, the testimony of the data annotators which labeled millions of ImageNet images, and the data subjects and the creators of the images within ImageNet. Academically, I situate this analysis within a larger theory and practice of infrastructure studies. Practically, I point to a vision for technology which is not based on practices of unrestricted data mining, exploited labor, and the use of images without meaningful consent.
This lecture satisfies requirements for CSCI 591: Research Colloquium.

Aerospace and Mechanical Engineering
Conferences, Lectures, & Seminars
Speaker: Zachary Manchester, Carnegie Mellon University
Talk Title: Composable Optimization for Robotic Motion Planning and Control
Abstract: Contact interactions are pervasive in key real-world robotic tasks like manipulation and walking. However, the non-smooth dynamics associated with impacts and friction remain challenging to model, and motion planning and control algorithms that can fluently and efficiently reason about contact remain elusive. In this talk, I will share recent work from my research group that takes an “optimization-first” approach to these challenges: collision detection, physics, motion planning, state estimation, and control are all posed as constrained optimization problems. We then build a set of algorithmic and numerical tools that allow us to flexibly compose these optimization sub-problems to solve complex robotics problems involving discontinuous, unplanned, and uncertain contact mechanics.
Biography: Zac Manchester is an Assistant Professor of Robotics at Carnegie Mellon University. He holds a Ph.D. in aerospace engineering and a B.S. in applied physics from Cornell University. Zac was a postdoc in the Agile Robotics Lab at Harvard University and previously worked at Stanford, NASA Ames Research Center and Analytical Graphics, Inc. He received a NASA Early Career Faculty Award in 2018 and has led four satellite missions. His research interests include motion planning, control, and numerical optimization, particularly with application to robotic locomotion and spacecraft guidance, navigation, and control.

We study one such social issue: homelessness in the U.S., by leveraging the remarkable capabilities of large language models to assist social work experts in analyzing millions of posts from Twitter. We introduce a framing typology: Online Attitudes Towards Homelessness (OATH) Frames: nine hierarchical frames capturing critiques, responses and perceptions. We release annotations with varying degrees of assistance from language models, with immense benefits in scaling: 6.5× speedup in annotation time while only incurring a 3 point F1 reduction in performance with respect to the domain experts. Our experiments demonstrate the value of modeling OATH-Frames over existing sentiment and toxicity classifiers. Our large-scale analysis with predicted OATH-Frames on 2.4M posts on homelessness reveal key trends in attitudes across states, time periods and vulnerable populations, enabling new insights on the issue. Our work provides a general framework to understand nuanced public attitudes at scale, on issues beyond homelessness.

Speaker: PrzemysÅaw (Przemek) Kazienko, Full Professor, Wroclaw University of Science and Technology
Talk Title: Responsible and User-Controllable Artificial Intelligence
Abstract: AI has a major positive impact on the economy and their users, providing them with a better experience, increased satisfaction, saving time and even expanding their horizons. Here, however, we focus on the potential negative impact of AI on humans, such as reinforcement of information bubbles, addiction, excessive use, reduced concentration, creativity and curiosity, enhanced consumerism, weakened autonomy to make free choices, interpersonal communication, and human relationships. We indicate what human features cause our increased susceptibility to the influence of RSs and what manipulation mechanisms they can potentially and even unintentionally exploit. We show some use cases in which the goals pursued by business may conflict with the goals of their users. it is also observable that AI-based approaches are evolving from decision-support to decision-making systems. Consequently, we propose the concept of Responsible AI, which respects the goals and beliefs of their users in addition to business goals. Another solution are user-controllable AI systems that may be incorporated in recently investigated Large Language Models (LLMs).
Biography: PrzemysÅaw (Przemek) Kazienko, Ph.D. is a full professor and leader of three research groups: AI and human values, HumaNLP, and Emognition at Wroclaw Tech (Wroclaw University of Science and Technology), Poland.

Talk Title: A Categorical Perspective of Encoding Real-World Data in Quantum Computers
Series: MHI Physics Joint Seminar Series
Abstract: The question of how to encode real-world data in quantum computer has a tremendous amount of importance in the quantum machine learning (QML) community. There are a few proposed metrics to quantify the efficacy of quantum feature maps with the most used criteria being 'expressibility' [1] and 'expressivity' [2]. However, as noted by the authors, there are shortcomings with these two techniques. Our empirical analysis of using the standard schemes of angle encoding, instantaneous quantum polynomial encoding (IQP), and amplitude encoding to perform machine learning tasks on different dataset reveals new insights into our metrics need to be considered when choosing a particular quantum encoding technique [3,4]. Using the perspective of category theory, we propose that quantum encoding techniques should preserve "structures" of classical data. Based on this insight, we proposed technique on comparing the entropy of a point-cloud against the analytic extension of von Neuman entropy applied to quantum operators [5], directly addressing one area of structure. [5]

ECE Seminar: Scaling Energy Efficiency of Mobile XR using Hardware/Software Codesign
Wed, Nov 13, 2024 @ 10:00 AM - 11:00 AM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. Scott Mahlke, Claude E. Shannon Professor of Engineering Sciences, EECS Department, University of Michigan
Talk Title: Scaling Energy Efficiency of Mobile XR using Hardware/Software Codesign
Abstract: Extended Reality (XR) is an important frontier in technology that combines virtual reality (VR) wherein users are immersed in a virtual world and augmented reality (AR) wherein virtual content is overlayed on the real world. Mobile XR focuses on the realization of AR/VR technologies in the context of portable headsets and other wearable technology, which severely restricts power dissipation and weight requirements for the onboard computing and sensory systems. The constraints preclude direct adoption of desktop/server solutions, instead require efficiency scaling by one to two orders of magnitude. To solve this problem, this work focuses on specialization of both the XR software stack and the underlying hardware. On the software side, simultaneous localization and mapping (SLAM) algorithms that track an agent's movements through an unknown environment are too computationally expensive to be applied in a brute-force manner. Instead, we develop SlimSLAM, a domain-specific runtime scheduler, which adapts SLAM algorithmic parameters based on input needs, minimizing computation while maintaining accuracy. SlimSLAM exploits information from a SLAM algorithm's state to detect and adjust over-provisioned parameters in real-time. SlimSLAM outperforms other adaptive approaches by an average of 2.3x with iso-accuracy. On the hardware side, we focus on in-memory computing that enables data parallel computation to occur in-place in an on-chip memory system, thereby eliminating data movement into and out of the processor and achieving high levels of data parallel computation. Specifically, we develop a duality cache architecture that flexibly transforms caches on demand into programmable in-memory accelerators that can execute arbitrary data-parallel programs commonly used in AR/VR. The cache accelerator outperforms a server-class GPU by 3.6x and CPU by 72.6x with only a 3.5% area cost across a range of data parallel applications.
Biography: Scott Mahlke is the Claude E. Shannon Professor of Engineering Sciences in the EECS Department at the University of Michigan. He leads the Compilers Creating Custom Processors research group that focuses on hardware/software technologies for scaling performance, energy efficiency, and cost of computing systems through specialization of the hardware down to the software it runs. Mahlke has won numerous awards including the 2022 IEEE B. Ramakrishna Rau Award, and is a Fellow of the IEEE and ACM.

Talk Title: Mechanism-based mechanical metamaterials
Abstract: The design and analysis of mechanism-based mechanical metamaterials is a relatively new and rapidly growing research area. It studies artificial "materials" that take advantage of "mechanisms" (that is, nontrivialenergy-free deformations) to achieve interesting macroscopic behavior.The relevant mechanics is nonlinear, since mechanisms involve large rotations. While there have been insightful studies of specific examples, some fundamental issues remain poorly understood. This talk will address two of them, namely (a) how to analyze a metamaterial's macroscopic behavior, and (b) whether linear elastic calculations can still be of use in the analysis of such systems, despite the fact that their mechanisms involve large rotations? My talk will start with a broad introduction to this area; then I'll discuss some recent work with Xuenan Li, which focuses on a particular (very rich) example -- the Kagome metamaterial. This system is interesting because it has infinitely many mechanisms, yet it behaves macroscopically as anonlinear elastic material whose stress-free states are compressive conformal maps.
Biography: Robert V. Kohn is Professor Emeritus of Mathematics at New YorkUniversity's Courant Institute of Mathematical Sciences. He received his PhD in Mathematics from Princeton in 1979, then held a two-year NSFPostdoctoral Fellowship which took him to the Courant Institute. He joined the faculty of the Courant Institute 1981, becoming Full Professor in 1988 and Silver Professor in 2017 before choosing to retire in 2022. Much of his work has addressed problems from mechanics and physics using methods from the calculus of variations and partial differential equations. He has, in particular, studied many examples of energy-driven pattern formation, in diverse systems ranging from shape-memory materials to thin elastic sheets. Professor Kohn's recognitions include selection as a member of the American Academy of Arts and Sciences, receipt of the American Mathematical Society's 2014 Leroy P. Steele Award, and being selected as both a SIAM Fellow and a Fellow of the American Mathematical Society.

Talk Title: Bone Mechanobiology On-a-Chip
Abstract: Bone has the remarkable ability to adapt its composition and structure to suit its mechanical environment. Osteocytes, bone cells embedded in the calcified matrix, are believed to be the mechanosensors and are responsible for orchestrating the bone remodeling process. However, the detailed cellular and molecular mechanisms underlying osteocyte mechanobiology are not well understood. Furthermore, how osteocytes communicate with other cell populations under mechanical loading remains unclear. Recently, several microfluidic platforms were developed to address these questions. In this talk, we will discuss intercellular communication between cell populations under mechanical loading and its implications in managing bone disorders such as bone metastasis prevention. Specifically, we studied the effects of vibration on breast cancer extravasation using our novel microfluidic co-culture platform. Our findings showed that vibration could reduce breast cancer migration by directly co-culturing osteocytes with cancer cells. Vibration also reduced trans-endothelial breast cancer migration (extravasation), suggesting that it may inhibit the early stages of bone metastasis. Additionally, we demonstrated that ZA, the standard treatment for osteolytic bone metastasis, could decrease breast cancer extravasation, and the effect was further enhanced under vibration. This is the first research that targets osteocyte-cancer interactions under vibration using an organ-on-chip system, which is an essential step toward developing a safe treatment for the high-risk population

Talk Title: Robust and Relaxed Temporal Logic Planning for Robot Systems
Series: CSC/CommNetS-MHI Seminar Series
Abstract: Robots are deployed in an increasing number of environments and applications, and tasked with ever complex missions with temporal, logical, and timing constraints. Practical and safety considerations impose that solutions are robust to perturbations and noise, and able to handle infeasible scenarios as best as possible. A planner for a self-driving car may not just return without a solution, it still needs to steer the car as best possible. A multi-agent team should not abandon a mission if one robot fails during deployment. A delivery robot should find alternatives and swap unavailable groceries based on the user's preferences. In this talk, we present and clarify the robustness and relaxation of temporal logic specifications. We present automata- and mixed integer linear programming (MILP) methods to address them in various mission settings for single- and multi-robot systems. We use automata to capture multiple relaxation semantics and provide a model for abstraction of rich user-preferences. We achieve scalability with respect to number of agents and specification complexity in multi-robot missions via MILP encodings while ensuring robust satisfaction in case of feasibility and partial satisfaction otherwise. We apply these techniques to coordinate heterogeneous teams of robots, robot swarms, and modular aerial robotic systems.

Algorithmic Tools for Redistricting: Fairness via Analytics

Speaker: Dr. David Shmoys, Laibe/Acheson Professor and Director of the Center for Data Science for Enterprise & Society - Cornell University
Talk Title: Algorithmic Tools for Redistricting: Fairness via Analytics
Abstract: The American winner-take-all congressional district system empowers politicians to engineer electoral outcomes by manipulating district boundaries. To date, most computational solutions focus on drawing unbiased maps by ignoring political and demographic input, and instead simply optimize for compactness and other related metrics. However, we maintain that this is a flawed approach because compactness and fairness are orthogonal qualities; to achieve a meaningful notion of fairness, one needs to model political and demographic considerations, using historical data. We will discuss a series of papers that explore and develop this perspective. We first present a scalable approach to explicitly optimize for arbitrary piecewise-linear definitions of fairness; this employs a stochastic hierarchical decomposition approach to produce an exponential number of distinct district plans that can be optimized via a standard set partitioning integer programming formulation. This enables a large-scale ensemble study of congressional districts, providing insights into the range of possible expected outcomes and the implications of this range on potential definitions of fairness. Further work extending this shows that many additional real-world constraints can be easily adapted in this framework (such as minimal county splits as was recently required in Alabama legislation in response to the US Supreme Court decision Milligan v. Alabama). In addition, one can adapt the same framework to heuristically optimize for other fairness-related objectives, such achieving a targeted number of majority minority districts (and in taking this approach, achieving stronger results than obtained by a prominent randomized local search approach known as “short bursts”).
We also show that our optimization infrastructure facilitates the study of the design of multi-member districts (MMDs) in which each district elects multiple representatives, potentially through a non-winner-takes-all voting rule (as was proposed in H.R. 4000 in an earlier session of Congress). We carry out large-scale analyses for the U.S. House of Representatives under MMDs with different social choice functions, under algorithmically generated maps optimized for either partisan benefit or proportionality. We find that with three-member districts using Single Transferable Vote, fairness-minded independent commissions can achieve proportional outcomes in every state (up to rounding), and this would significantly curtail the power of advantage-seeking partisans to gerrymander.
This is joint work with Wes Gurnee, Nikhil Garg, David Rothschild, Julia Allen, Cole Gaines, David Domanski, Rares-Stefan Bucsa, and Daniel Brous.
This lecture satisfies requirements for CSCI 591: Research Colloquium.

Talk Title: The Art and the Science of Metal 3D Printing
Abstract: This is the title of a class I teach at Stanford on metal 3D printing, and it reflects my perspective on where metal 3D printing is today: part art and part science, because of the complexities and multiple physical processes at play. Printing strategies are inspired in science, but when it comes time to print a new alloy or a complex geometry, the art storms in to help bridge the gaps in understanding. A goal in metal 3D printing research is to shift this balance towards science.
In this talk I will first describe the main physical processes involved one of the most widely adopted metal 3D printing technologies, Laser Powder Bed Fusion (LPBF), and then showcase three vignettes of contributions we made: (a) in-situ alloying and printing of tantalum-tungsten alloys, (b) the “surprising” behavior of some martensitic steels under 3D printing conditions, (c) two ways to alter the optical absorptivity of highly-reflective metallic powders to facilitate printing of copper in some standard printers. The art and the science are interweaved in the three contributions.
Biography: Adrian J. Lew is a Professor of Mechanical Engineering and the Institute for Computational and Mathematical Engineering at Stanford University. He graduated with the degree of Nuclear Engineer from the Instituto Balseiro in Argentina, and received his master of science and doctoral degrees in Aeronautics from the California Institute of Technology. He is a fellow of the International Association for Computational Mechanics, and has been awarded Young Investigator Award by the International Association for Computational Mechanics, the ONR Young Investigator Award, the NSF Career Award, and the Ferdinand P. Beer & Russel Johnston, Jr., Outstanding New Mechanics Educator Award from the American Society of Engineering Education. He has also received an honorable mention by the Federal Communication Commission for the creation of the Virtual Braille Keyboard.

Speaker: Karen Mulleners, EPFL
Talk Title: Shaping up to Explore and Exploit Unsteady Fluid-structure Interactions
Abstract: Nature is full of thin, flexible objects that bend, flutter, or flap in the wind or the water such as leaves of trees and bushes, insect wings, and fish fins. A remarkable feature that is common to these objects is their ability to deform when interacting with the air or the water in a way that benefits them. Leaves of trees bend in the wind to reduce their resistance and the loads on their stems. The flexibility of insect wings and fish fins can reduce the effort the animals need to stay aloft or to propel themselves and increases their performance and agility. Leaves, insect wings, and fish fins come in a myriad of different shapes and sizes. Surprisingly, the influence of the shape of thin flexible objects on their fluid structure interactions has not yet received much attention. In our lab, we design unsteady fluid-structure interaction experiments to close that gap and fundamentally study how the shape of flexible structures and their ability to reconfigure changes their fluid dynamic performance and resilience in dynamic fluid environments. I will present recent work including experimental investigations of the fluid-structure interactions of deformable flapping wings, reconfiguring disks, and flapping flags.
Biography: Karen Mulleners is an associate professor in the institute of mechanical engineering in the school of engineering at EPFL. She is the head of the unsteady flow diagnostics laboratory (UNFoLD). She is an experimental fluid dynamicist who focuses on unfolding the origin and development of unsteady flow separation and vortex formation. Karen studied physics in Belgium (Hasselt University, previously Limburgs Universitair Centrum) and the Netherlands (TU Eindhoven). She received her PhD in mechanical engineering from the Leibniz Universität Hannover in Germany in 2010 for her work on dynamic stall on pitching airfoils that she conducted as a member of the German aerospace centre (DLR) in Göttingen. Before joining EPFL in 2016, Karen was a (non-tenure track) assistant professor at the Leibniz Universität Hannover in Germany.

Speaker: Daniel Neuhold, CEO, LoconIQ R&D | Klagenfurt, Austria
Talk Title: Entrepreneurial Road Towards a Robust 3D Tracking Solution with UWB
Abstract: As industries strive to enhance quality control and to ensure thorough traceability, the demand for sophisticated 3D tracking solutions drastically increased over the last years. LoconIQ stands out with a robust solution to empower new applications with high-precision and real-time 3D tracking. The company’s main innovations are a time-of-flight based ranging algorithm that allows for sub-centimeter distances measurements and a proprietary sensor fusion that integrates ultra-wideband (UWB) data and auxiliary sensors. The solution utilizes UWB signal characteristics and noise/outlier classification models of sensors to facilitate a weighted unscented Kalman Filter (UKF) approach for the localization. With these innovations, LoconIQ delivers a robust 3D tracking solution at a centimeter level accuracy with latencies of only a few ms. The talk will provide insights into the technology and provide real-life examples, outlining step-by-step improvements from a simple Kalman Filter based localization approach to the company’s current UKF with weighting and an advanced sensor fusion. The talk will, furthermore, provide some insights into the applications for such a technology and address the entrepreneurial journey from a university spin-off to a million-dollar company.
Biography: The talk will be given by Daniel Neuhold, who embarked on his Ph.D. journey focusing on wireless communication for aeronautical applications. More particularly, working with Airbus in a project to eliminates wires from commercial airplanes and Ariane carrier rockets. Aiming to substitute data cables with wireless communication to drastically reduce the aircraft’s weight. Daniel then pivoted to the utilization of the used ultra-wide band (UWB) communication to facilitate real-time and high-precision wireless ranging. With this research topic, Daniel performed a seven-months long research stay at the University of Southern California in 2018. After which, he pursued his entrepreneurial path and patented algorithms for precise and low-latency ranging. These efforts culminated in a first prototype solution, which demonstrated the capabilities of the developed technology to raise millions in funding, leading to the incorporate and scale-up of the company. LoconIQ now enables robust and high-precision 3D tracking with a small and battery-powered sensor device, that comes as a turnkey solution right out-of-the-box.

Talk Title: Lifting Surfaces at Aerodynamically low Reynolds numbers: Recent Advances
Abstract: Flow development over lifting surfaces in aerodynamically low Reynolds number flows (Re<500,000) is largely governed by boundary layer separation and subsequent separated sear layer development on the suction side. In the time-averaged sense, rapid laminar-to-turbulent transition in the separated shear layer leads to the formation of a closed recirculating flow region referred to as the Laminar Separation Bubble (LSB). However, LSBs feature rich dynamics associated with the formation and evolution of shear layer roll up vortices leading to laminar-to-turbulent transition. Linear stability analysis confirms that there is a continuous stability spectrum spanning laminar boundary later and separated shear layer regions, linking LSB transition and shear layer vortex shedding to upstream amplification of disturbances that originate from free-stream perturbations in the receptivity region. Flow development in the aft portion of the bubble is highly three-dimensional even on nominally two-dimensional geometries. It manifests in progressive deformation of shear layer vortices and subsequent vortex breakdown. On a finite wing, an open LSB forms due to wing tip and root effects. Away from the affected regions, however, LSB topology and dynamics appear to be quasi two-dimensional despite effective angle of attack variation across the span. Changes in operating conditions, including velocity and angle of attack, can lead to significant transient flow developments associated with bubble bursting (i.e., sudden lengthening or full separation without subsequent reattachment) and LSB re-formation, accompanied by substantial changes in aerodynamic loads.

Speaker: Tom Goldstein, Volpi-Cupal Professor of Computer Science at the University of Maryland, and director of the Maryland Center for Machine Learning
Talk Title: AI Safety Issues in Generative Models: Memorization and Detection
Abstract: Machine learning systems are built using large troves of training data that may contain private or copyrighted content. In this talk, I'll survey a number of data memorization issues that arise when sensitive data is used. I'll begin by talking about data privacy issues that arise when using generative models. These models are often created using a training objective that explicitly promotes their ability to regenerate their training data. I'll discuss how diffusion models can reproduce their training data, leading to potential legal issues. I'll also discuss methods for detecting large language model content and explore ways in which the ability to reproduce training data complicates our ability to detect LLM-produced text.
Biography: Tom Goldstein is the Volpi-Cupal Professor of Computer Science at the University of Maryland, and director of the Maryland Center for Machine Learning. His research lies at the intersection of machine learning and optimization, and targets applications in computer vision and signal processing.

Visit links below to subscribe and for details on upcoming seminars: https://www.isi.edu/isi-seminar-series/ https://www.isi.edu/events/ Recent large language models (LLMs) have only shown potential for reasoning with text and image data. We explore this reasoning ability with one of the most important data formats: time-series. Capturing the sequential nature of time-series data is crucial to power applications in finance and healthcare. This talk presents a first-of-its-kind benchmark that focuses on truly understanding time-series data and goes beyond the existing evaluations. Additionally, we will discuss the notable limitations of existing works claiming that LLMs can perform forecasting. Our analysis across such models finds that simply removing the LLMs or replacing them with a basic attention layer improved results in most cases, and also led to better scalable solutions.
Biography: Vinayak Gupta is a researcher in the AI Research Group at the Lawrence Livermore National Laboratory. Prior to this, he was a postdoctoral scholar at the University of Washington, Seattle, and an AI Scientist at IBM Research. His research focuses on mining large-scale time-series data, and more recently, he has been working on leveraging LLMs to jointly understand text+time-series.

Talk Title: FPGA-Chiplet Architectures and Circuits for 2.5D/3D 6G Intelligent Radios
Series: ISSS
Abstract: The number of connected devices is expected to reach 500 billion by 2030, which is 59-times larger than the expected world population. Objects will become the dominant users of next-generation communications and sensing at untethered, wireline-like broadband performance, bandwidths, and throughputs. This sub-terahertz 6G communication and sensing will integrate security and intelligence. It will enable a 10x to 100x increase in peak data rates. FPGAs are well positioned to enable intelligent radios for 6G when coupled with high-performance chiplets incorporating RF circuits, data converters, and digital baseband circuits incorporating machine learning and security. This talk presents use of 2.5D and 3D heterogeneous integration of FPGAs with chiplets, leveraging Intel's EMIB/Foveros technologies with focus on one emerging application driver: FPGA-based 6G sub-THz intelligent wireless systems. Nano-, micro-, and macro-3D heterogeneous integration is summarized, and previous research in 2.5D chiplet integration with FPGAs is leveraged to forge a path towards new 3D-FPGA based 6G platforms. Challenges in antenna, packaging, power delivery, system architecture design, thermals, and integrated design methodologies/tools are briefly outlined. Opportunities to standardize die-to-die interfaces for modular integration of internal and external circuit IPs are also discussed.

Automatic Evaluation of Clinical Notes Generated from Doctor-Patient-Conversations

Talk Title: Automatic Evaluation of Clinical Notes Generated from Doctor-Patient-Conversations
Abstract: Detailed detailed clinical documentation based on doctor-patient conversations is a necessary yet burdensome task for physicians and is often cited as one of the leading causes of physician burn-out. One way to reduce the documentation workload on physicians is to hire medical scribes, who assist in writing clinical notes. However, this option is costly and difficult to scale, putting it beyond the reach of many practitioners. This has led to the emergence of the ``ambient clinical documentation'' framework, where the conversation between doctor and patient is recorded and transcribed (with the patient's permission) and passed to a clinically trained Language Model (LM) which generates the corresponding note. Despite the recent improvements in their performance, modern LMs still make many errors that are unacceptable in a medical setting and can generate clinical notes that are of poor quality. For example, they may miss critical information, contain hallucinated content, or include important information in wrong note sections. Delivering poor-quality notes to physicians can be an extra burden, potentially resulting in a more time-consuming note creation process than simply starting from scratch. This proves the necessity of evaluating LM-generated clinical notes in a scalable and efficient manner. In this presentation we will introduce few such approaches and examine their weaknesses and strengths.
This lecture satisfies requirements for CSCI 591: Research Colloquium.
