TILOS Seminar: Deep Generative Models and Inverse Problems

Virtual

Alexandros G. Dimakis, Professor, The University of Texas at Austin Abstract: Sparsity has given us MP3, JPEG, MPEG, Faster MRI and many fun mathematical problems. Deep generative models like GANs, VAEs, invertible flows and Score-based models are modern data-driven generalizations of sparse structure. We will start by presenting the CSGM framework by Bora et al. […]

TILOS Seminar: Reasoning Numerically

Virtual

Sicun Gao, Assistant Professor, UC San Diego Abstract: Highly-nonlinear continuous functions have become a pervasive model of computation. Despite newsworthy progress, the practical success of “intelligent” computing is still restricted by our ability to answer questions regarding their quality and dependability: How do we rigorously know that a system will do exactly what we want it […]

TILOS Seminar: The FPGA Physical Design Flow Through the Eyes of ML

Virtual

Dr. Ismail Bustany, Fellow at AMD Abstract: The FPGA physical design (PD) flow has innate features that differentiate it from its sibling, the ASIC PD flow. FPGA device families service a wide range of applications, have much longer lifespans in production use, and bring templatized logic layout and routing interconnect fabrics whose characteristics are captured by […]

TILOS Seminar: How to use Machine Learning for Combinatorial Optimization? Research Directions and Case Studies

Virtual

Sherief Reda, Professor, Brown University and Principal Research Scientist at Amazon Abstract: Combinatorial optimization methods are routinely used in many scientific fields to identify optimal solutions among a large but finite set of possible solutions for problems of interests. Given the recent success of machine learning techniques in classification of natural signals (e.g., voice, image, […]

TILOS Seminar: Machine Learning for Design Methodology and EDA Optimization

Virtual

Haoxing Ren, NVIDIA Abstract: In this talk, I will first illustrate how ML helps improve design quality as well as design productivity from design methodology perspective with examples in digital and analog designs. Then I will discuss the potential of applying ML to solve challenging EDA optimization problems, focusing on three promising ML techniques: reinforcement learning […]

TILOS Seminar: Non-convex Optimization for Linear Quadratic Gaussian (LQG) Control

Virtual

Yang Zheng, Assistant Professor, UC San Diego Abstract: Recent studies have started to apply machine learning techniques to the control of unknown dynamical systems. They have achieved impressive empirical results. However, the convergence behavior, statistical properties, and robustness performance of these approaches are often poorly understood due to the non-convex nature of the underlying control problems. […]

TILOS Seminar: On Policy Optimization Methods for Control

Virtual

Maryam Fazel, Professor, University of Washington Abstract: Policy Optimization methods enjoy wide practical use in reinforcement learning (RL) for applications ranging from robotic manipulation to game-playing, partly because they are easy to implement and allow for richly parameterized policies. Yet their theoretical properties, from optimality to statistical complexity, are still not fully understood. To help […]

TILOS Seminar: Robust and Equitable Uncertainty Estimation

Virtual

Aaron Roth, Professor, University of Pennsylvania Abstract: Machine learning provides us with an amazing set of tools to make predictions, but how much should we trust particular predictions? To answer this, we need a way of estimating the confidence we should have in particular predictions of black-box models. Standard tools for doing this give guarantees […]

TILOS Seminar: Rare Gems: Finding Lottery Tickets at Initialization

Virtual

Dimitris Papailiopoulos, Associate Professor, University of Wisconsin–Madison Abstract: Large neural networks can be pruned to a small fraction of their original size, with little loss in accuracy, by following a time-consuming “train, prune, re-train” approach. Frankle & Carbin in 2019 conjectured that we can avoid this by training lottery tickets, i.e., special sparse subnetworks found at […]

TILOS Seminar: Causal Discovery for Root Cause Analysis

Virtual

Murat Kocaoglu, Assistant Professor, Purdue University Abstract: Cause-effect relations are crucial for several fields, from medicine to policy design as they inform us of the outcomes of our actions a priori. However, causal knowledge is hard to curate for complex systems that might be changing frequently. Causal discovery algorithms allow us to extract causal knowledge from […]
