    Title: Improving Decision-Making in Search Algorithms with Machine Learning for Combinatorial Optimizations  
     
    Date and Time: August 1st, 2024: 3:30p - 5:30p  
     
    Location: EEB 349
       
    Committee Members: Sven Koenig, Bistra Dilkina, Jyotirmoy Deshmukh, Meisam Razaviyayn, Peter Stuckey  
     
    Abstract: Designing algorithms for combinatorial optimization problems (COP) is an important and challenging task since it concerns a wide range of real-world problems, such as vehicle routing, path planning, and resource allocation problems. Most COPs are NP-hard to solve, and many research algorithms have been developed for them in the past few decades. Decision-making, such as partitioning or pruning the search space and prioritizing exploration in the search space, is crucial to the efficiency and effectiveness of the search algorithms. Many of those heavily rely on domain expertise and human-designed strategies.  
    In this thesis, we hypothesize that one can leverage machine learning frameworks to improve decision-making strategies in different search algorithms for combinatorial optimization problems. We validate the hypothesis on the problems of multiagent path finding and solving mixed integer linear programs, introducing different machine learning techniques to advance a few state-of-the-art optimal and heuristic search algorithms for the two problems.

    Title: Controllable Trajectory Generation  
     
    Date and Time: Monday, August 5th, 2024: 1:00p -3:00p   
     
    Location: Ronald Tutor Hall of Engineering (RTH) - 306        
     
    Committee Members: Prof. Cyrus Shahabi (Chair), Prof. Bistra Dilkina, Prof. Marlon Boarnet and Prof. Xiong Li
     
    Abstract: Accessing realistic human movements (aka trajectories) is essential for many application domains, such as urban planning, transportation, and public health (e.g., understanding the spread of an epidemic). However, due to privacy and commercial concerns, real-world trajectories are not readily available, giving rise to an important research area of generating synthetic but realistic trajectories. Traditional rule-based methods rely on predefined heuristics and distributions that fail to capture complicated transition patterns in human mobility. Inspired by the success of deep neural networks (DNN), data-driven methods learn underlying human decision-making mechanisms and generate synthetic trajectories by directly fitting real-world data. Despite this progress, existing approaches lack mechanisms to control the generation process, which prevents the incorporation of prior knowledge and the spatiotemporal specification of certain visits. This lack of control on the generated trajectories greatly limits their practical applicability. In addition, existing studies on trajectory mining applications often project GPS coordinates onto discrete geographical grids and time intervals. However, modeling human movements requires algorithms that can effectively capture inherently complex spatial and temporal dependencies and transforming trajectories into regular grids and time intervals cannot accurately model real-world trajectories with irregular moving patterns. This thesis addresses the above two shortcomings and proposed generation algorithms under various control settings.    
     
    In this thesis defense, I will present my work on controllable trajectory generation. I will first provide the motivations and review previous work on implicitly controlled trajectory generation via clustering. Subsequently, I will formally define the Constraint Trajectory Generation problem and our framework that operates within continuous spatiotemporal space, enabling the direct generation of geographical coordinates and the duration of each visit in a trajectory. In conclusion, I will discuss future directions for the development of trajectory generation models

    Information Sciences Institute

    Speaker: Arinbjorn Kolbeinsson, University of Virginia

    Talk Title: Composable Interventions for Language Models

    Abstract: Virtual zoom link: https://usc.zoom.us/j/7042850182?pwd=OTQ3aW9LUjErTC9iWGRFQUg0LzlOdz09&omn=96405030645Meeting ID: 704 285 0182Meeting password: 832239
    Abstract: Test-time interventions for language models can enhance factual accuracy, mitigate harmful outputs, and improve model efficiency without costly retraining. But despite a flood of new methods, different types of interventions are largely developing independently. In practice, multiple interventions must be applied sequentially to the same model, yet we lack standardized ways to study how interventions interact. We fill this gap by introducing composable interventions, a framework to study the effects of using multiple interventions on the same language models, featuring new metrics and a unified codebase. Using our framework, we conduct extensive experiments and compose popular methods from three emerging intervention categories — Knowledge Editing, Model Compression, and Machine Unlearning. Our results from 310 different compositions uncover meaningful interactions: compression hinders editing and unlearning, composing interventions hinges on their order of application, and popular general-purpose metrics are inadequate for assessing composability. Taken together, our findings showcase clear gaps in composability, suggesting a need for new multi-objective interventions. All of our code is public: https://github.com/hartvigsen-group/composable-interventions

    Biography: Arinbjörn Kolbeinsson is currently serving as a visiting scholar at the University of Virginia, focusing on responsible and accurate models for health and biomedicine. His recent research explores the editing and efficiency of language models, along with the development of composable intervention techniques. Previously, Arinbjörn was a machine learning scientist at Evidation Health Inc., where he developed innovative methods to predict health outcomes using high-frequency multi-modal data. His work was pivotal in advancing differential privacy, disease modeling, and reinforcement learning for health applications. Arinbjörn completed his Ph.D. in Biostatistics at Imperial College London in 2020, specializing in deep learning for health outcome prediction.

    Title: Toward Enabling Large-scale Outdoor Augmented Reality    
     
    Date: August 12, 2024
     
    Location: SAL- Henry Salvatori Computer Science Center 213
     
    Time: 10:00 AM - 12:00 PM
     
    Committee members: Ramesh Govindan, Konstantinos Psounis, Mukund Raghothaman
     
    Abstract:This thesis advances outdoor augmented reality (AR) by addressing critical challenges in urban situational awareness (Urban Situational Awareness) through the development of three innovative systems: Cooperative Infrastructure Perception (CIP), UbiPose, and SplatLoc. Urban Situational Awareness aims to enhance AR users’ understanding of their surroundings by accurately integrating dynamic digital content with the physical environment. This research focuses on two fundamental aspects of outdoor AR: dynamic content rendering and precise pose estimation. CIP leverages infrastructure LiDARs to provide real-time, multi-angular perception of urban spaces, enabling a "virtual see-through" capability. This system also introduces methods for extracting dynamic objects, such as pedestrians and vehicles, significantly improving AR accuracy and responsiveness. UbiPose uses aerial meshes to extend AR coverage, though it requires computationally intensive algorithms to address aerial image distortions. SplatLoc employs Gaussian Splatting (GSplat) from crowd-sourced street-level images, generating high-quality synthetic views for efficient and accurate pose estimation.    
     
    Two key contributions are highlighted. First, the exploration of how to extract dynamic content in urban settings, enhancing AR by detecting and representing moving objects. Second, the exploration of optimal map representations for outdoor AR pose estimation, balancing coverage, accuracy, and computational efficiency. The research proposes future directions, including creating high-quality GSplat using aerial images to improve availability and efficiency. It also discusses the need for efficient map update mechanisms to ensure timely and accurate real-world reflections.    By addressing these challenges, this thesis lays the groundwork for more immersive and reliable outdoor AR applications, paving the way for transformative experiences in urban environments.

    Talk Title: Interpretable Quantum Advantage in Neural Sequence Learning

    Series: Quantum Science & Technology Seminar Series

    Abstract: Quantum neural networks have been widely studied in recent years due to their potential practical utility and recent results showing their ability to efficiently express certain classical data. However, analytic results to date rely on assumptions and arguments from complexity theory. As a result, there is little intuition regarding the source of the expressive power of quantum neural networks or for which classes of classical data any advantage can be reasonably expected to hold. In this study, we examine the relative expressive power between a broad class of neural network sequence models and a class of recurrent models based on quantum mechanics. We demonstrate that quantum contextuality is the source of an unconditional memory separation in the expressivity of the two model classes. Using this intuition, we study the relative performance of our introduced model on a standard translation dataset exhibiting linguistic contextuality. Our quantum models outperform state-of-the-art classical models, even in practice. Finally, I will briefly discuss future directions of quantum neural networks and their potential connections to concepts in condensed matter physics, such as Berry phase and spin glass.

    Biography: Xun Gao is an assistant professor at University of Colorado Boulder and an associate fellow at JILA. He got his PhD from Tsinghua University under the supervision of Luming Duan. Then he was a postdoc at Harvard University from Mikhail Lilian's group. His research interests are quantum computational advantage and quantum machine learning.

  • CAIS seminar: How to make optimal decisions (that are unfair, biased and non-objective)

    CAIS seminar: How to make optimal decisions (that are unfair, biased and non-objective)

    Fri, Aug 23, 2024 @ 10:30 AM - 11:30 AM

    Thomas Lord Department of Computer Science

    Conferences, Lectures, & Seminars


    Speaker: Prof. Guido Tack, Monash University

    Talk Title: How to make optimal decisions (that are unfair, biased and non-objective)

    Abstract: Optimisation technology promises to help us make better decisions: plan the best route on a map, deliver goods quickly and with low emissions, construct efficient staff rosters, or design complex industrial plants. But most of these optimal decisions are in fact compromises. For example, there may be many “optimal” staff rosters that enable an organisation to function effectively and at the lowest possible cost. But some of those “optimal” rosters may be very unfair for certain staff. What if one of your staff asks you why they always get the graveyard shift, and after you’ve analysed the problem, you have to tell them it’s because their name starts with an “A”? This talk is about how optimisation technology can introduce bias and unfairness in subtle ways, and what needs to be done to fix this problem.

    Biography: Guido Tack is an Associate Professor in the Department of Data Science and Artificial Intelligence at Monash University, Australia. His research focuses on combinatorial optimisation, in particular architecture and implementation techniques for constraint solvers, translation of constraint modelling languages, and industrial applications. Guido leads the development of the MiniZinc constraint modelling language and toolchain, and he is one of the leading developers of Gecode, a state-of-the-art constraint programming library. Guido’s broader research interests include programming languages and computational logic.

    Talk Title: Promoting tissue healing and regeneration using proteoglycan mimetics

    Abstract: Proteoglycans play an important role in extracellular matrix remodeling, homeostasis, and signaling. Due to their negatively charged glycosaminoglycan chains as well as distinct core protein structures, they interact with a variety of molecules, including matrix proteins, growth factors, cytokines and chemokines, pathogens, and enzymes. Here we focus on two bioconjugates that were designed to mimic features of existing proteoglycans. The first models the biological activity of the small leucine-rich proteoglycan, decorin. Like native decorin, our decorin mimetic plays a key role in collagen organization and wound healing. Recently, we have augmented the decorin mimetic with peptide ligands to the avb3 integrin receptor found on endothelial and endothelial progenitor cells. The avb3 ligand confers angiogenic activity to the decorin mimetic and supports wound healing in an ischemic environment in diabetic animals. The second mimetic is designed to target inflamed endothelium to restore physical barrier function of the endothelial glycocalyx. By restoring barrier function, the glycocalyx mimetic reduces intravascular thrombosis and inflammation thereby improving healing outcomes following ischemia reperfusion injury in animal models.

    Biography: Dr. Panitch received bachelor’s degrees from Smith College in Biochemistry and from the University of Massachusetts-Amherst in Chemical Engineering. She completed her Ph.D. in Polymer Science and Engineering from the University of Massachusetts. After a postdoctoral fellowship at the Swiss Federal Institute of Technology (ETH) and University of Zurich. She started her first faculty position at Arizona State University in 1999 where she was awarded an NSF CAREER award. She is currently the chair of the Wallace H. Coulter Department of Biomedical Engineering at Emory University and Georgia Tech. She is a member and Fellow of the Biomedical Engineering Society, the American Institute for Medical and Biological Engineers (AIMBE)and the National Academy of Inventors. She also serves as an Editor for the Journal of Colloids and Surfaces B: Biointerfaces.

    Title: 
    Building Generalizable Language Models for Code Processing
     
    Abstract:
    Successful deployment of any AI model requires generalization to previously unseen, real-world scenarios. Lack of generalization in models can lead to outcomes ranging from reduced performance to potential legal liabilities. In this thesis, I explore generalization challenges in large language models for code processing. I will discuss three different generalization concerns that language models for code processing can exhibit, and present my progress in building models that can overcome those. 1) I will start by discussing compositional generalization issues, where models must adapt to previously unseen instruction combinations 2) Next I will talk about out-of-domain generalization, and how distribution shifts within single projects or corporations can affect model performance, and how to overcome it. 3) Finally, I will talk about generalization of advanced models to programming languages with fewer resources.

    Talk Title: The Finite Element Method and Isogeometric Analysis: Past, Present, Future

    Abstract: I will begin by probing into the past to discover the origins of the Finite Element Method (FEM), and then trace the evolution of those early developments to the present day in which the FEM is ubiquitous in science, engineering, mathematics, and medicine, and the most important discretization technology in Computational Mechanics. However, despite its enormous success, there are still problems with contemporary technology, for example, building meshes from Computer Aided Design (CAD) representations is labor intensive, and a significant bottleneck in the design-through-analysis process; the introduction of geometry errors in computational models that arise due to feature removal, geometry clean-up and CAD “healing,” necessary to facilitate mesh generation; the inability of contemporary technology to “close the loop” with design optimization; and the failure of higher-order finite elements to achieve their full promise in industrial applications. These issues are addressed by Isogeometric Analysis (IGA), the vision of which was first presented in a paper published October 1, 2005 [1]. Since then, IGA has become a focus of research within both FEM and CAD and is now a mainstream analysis methodology that has provided a new paradigm for computational model development [2-4]. The key concept utilized in the technical approach is the development of a new foundation for FEA, based on rich geometric descriptions originating in CAD, more tightly integrating design and analysis. Industrial applications and commercial software developments have expanded recently. I will briefly present the motivation leading to IGA, its status, recent progress, areas of current activity, and what it offers for analysis model development and the design-through-analysis process. I will also argue that IGA provides an alternative and more robust approach to higher-order finite element analysis, filling the gap between low-order, geometrically versatile approaches and high-order, geometrically restrictive spectral methods. Finally, I will speculate on the future, the technologies that will prevail, computer developments, and the role of machine learning. [1] T.J.R. Hughes, J.A. Cottrell and Y.

    Talk Title: From legged robots to knitted ones

    Series: EE598 Seminar Series

    Abstract: Traditional robotics assumes rigid bodies interacting with rigid environments. However, the real world is soft. Robots will need to be able to move over materials like sand, snow, and leaf litter, and will need to be able to interact with fruits, fabrics, and of course humans. I will discuss two types of soft interactions between a robot and the world: Robot locomotion on granular media, and the use of knitting as a computational fabrication method to create soft sensors for robots.
     

    Biography: Dr. Sonia Roberts is an Assistant Professor of Computer Science at Wesleyan University working on knitted sensors for soft robot skins and legged robot locomotion on granular media. In 2023, she completed a postdoc with Prof. Kris Dorsey at Northeastern as part of the Institute for Experiential Robotics, where she worked on soft origami sensors. She received her PhD in Electrical and Systems Engineering from the University of Pennsylvania in 2021, where she worked with Prof. Dan Koditschek in the GRASP Lab to develop a reactive controller to reduce the energetic cost of transport for legged robots on sand. Prior to coming to Penn, Sonia worked at Janelia Farm Research Campus on a team building a rough behavioral map of the fruit fly brain, and with John Long using evolutionary robotics tools to answer biological questions at Vassar College.

    Abstract: There is simultaneously an interest for more energy-efficient hardware in challenging applications, as well as a drive to overhaul the von Neumann architecture toward more brain-like architectures. I will describe our in-memory approach that applies to both these two topic areas, especially where emerging memories like memristors can be utilized with traditional CMOS in new circuits and architectures.  Such hybrid circuits can yield challenges in variability, offer many benefits. I will discuss our modified Hopfield neural network accelerator for challenging optimization problem classes such as Boolean satisfiability (3-SAT), showing performance comparisons to competing approaches with both mature and emerging technologies. In complementary work, we build new architectures around content addressable memories (CAM), which offer a highly parallel pattern look-up capability. Designs are improved utilizing non-volatile and analog memristive devices for higher data density and lower energy than CMOS-only counterparts. We utilize such circuits in a variety of associative computing applications, including security, genomics, and machine learning. Going further, we are interested in how learning can be incorporated into such memory circuits and we describe a modified "differentiable" CAM circuit that is compatible with gradient-based training algorithms and illustrate some applications of such a circuit.

    Talk Title: Navigating an Early Career in Biopharmaceuticals: From Graduate Research to Industry Expertise

    Abstract: In this seminar, we will explore an early-stage career journey through various facets of the biopharmaceutical industry. Starting with a brief introduction that highlights graduate work at the University of Southern California in the Chung lab, we focus on a project utilizing polymeric micelle nanoparticles for targeted drug delivery to treat polycystic kidney disease. The talk will then delve into an industrial application, looking at process development of a pipeline vaccine in late-stage clinical development. Following this, we examine the opposite end of the regulatory approval spectrum and investigate the challenges of commercial production of a viral vector biologic. The seminar will conclude with practical tips and case studies on navigating the industry, to offer valuable insights for aspiring professionals.
