Abstract & Biography
 
Title: Generalization in Data-Driven Control
Prof. Sergey Levine (UC Berkeley)
 
Abs:
Current machine learning methods are primarily for tackling prediction problems, which are almost cast as supervised learning tasks. Despite decades of advances in reinforcement learning and learning-based control, the applicability of these methods to domains that require open-world generalization -- autonomous driving, robotics, aerospace, and other applications, -- remain challenging. Realistic environments require effective generalization, and effective generalization requires training on large and diverse datasets that are representative of the likely-time scenarios. I will discuss why this poses a particular challenge for learning-based control, and present some recent research directions that aim to address this challenge. I will discuss how offline reinforcement learning algorithms can make it possible for learning-based control systems to utilize large and diverse real-world datasets, how the use of diverse data can enable robotic systems to navigate real-world environments, and how multi-task and contextual policies can enable broad generalization to a range of user-specific goals.
 
Bio:
Sergey Levine received a BS and MS in Computer Science from Stanford University in 2009, a Ph D., in Computer Science from Standford University in 2014. He joined the faculty of the Department of Electrical Engineering and Computer Science at Berkeley in fall 2016. His work focuses on machine learning for decision making and control, with an emphasis on deep learning and reinforcement learning algorithms. Applications of his work include autonomous robots and vehicles, as well as computer vision and graphics. His research includes developing algorithms for end-to-end training of deep neural network policies that combine perception and control, scalable algorithms for inverse reinforcement learning, deep reinforcement learning algorithms, and more.
 
 
Title: Embedded Convex Optimization for Control
Prof. Stephen Boyd (Stanford University)
 
Abs:
Control policies that involve the real-time solution of one or more convex optimization problems include model predictive (or receding horizon) control, approximate dynamic programming, and optimization based actuator allocation systems. They have been widely used in applications with slower dynamics, such as chemical process control, supply chain systems, and quantitative trading, and are now starting to appear in systems with faster dynamics. In this talk I will describe a number of advances over the last decade or so that make such policies easier to design, tune, and deploy. We describe solution algorithms that are extremely robust, even in some cases division free, and code generation systems that transform a problem description expressed in a high level domain specific language into source code for a real-time solver suitable for control. The recent development of systems for automatically differentiating through a convex optimization problem can be used to efficiently tune or design control policies that include embedded convex optimization.

Title: Multi-resolution for Graphs: Graphical Model to Graph Classification for Alzheimer's Disease Analysis
±è¿øÈ­ ±³¼ö 
Æ÷Ç×°ø´ë
 
Abs:
Tremendous literature indicate that Brain Networks, defined by associations between different regions of interests (ROIs) in the brain, show early signs of neurodegenerative diseases. Brain networks are naturally represented as Graphs that consists of sets of nodes and edges. Their irregular structures differentiate the graphs from traditional imaging data in Euclidean spaces, and thus it requires sophisticated machine learning and signal processing techniques for a downstream analysis. In this talk, I will introduce our recent effort on analyzing  graph data in neuroimaging studies using the concept of multi-resolution on graph structure. I will first introduce construction of multi-resolution graphical model, which will behave as a core component for Multi-resolution Edge Network (MENET) architecture for graph classification in the second part. Results on Brain Network analyses will be reported that identify disease-specific variations in the brain due to Alzheimer’s Disease (AD).

This tutorial consists of two parts. In the first part, we will learn the basics of language models, including traditional n-gram language models as well as modern LSTM and Transformer (Vaswani et al., 2017)-based ones. In the second part, I will discuss how large language models have transformed AI research in last 4 years, starting from ELMo (Peters et al., 2017) to GPT-3 (Brown et al., 2020).
