Theory Lunch
Thu, Oct 31, 2019 @ 12:15 PM - 02:00 PM
Thomas Lord Department of Computer Science
Conferences, Lectures, & Seminars
Speaker: Federico Echenique, Professor of Economics at CalTech
Talk Title: The Edgeworth Conjecture with Small Coalitions and Approximate Equilibria in Large Economies
Abstract: A talk about the paper Federico Echenique worked on with Siddharth Barman entitled "The Edgeworth Conjecture with Small Coalitions and Approximate Equilibria in Large Economies." The paper shows that deciding if an allocation is approximately Walrasian can be done in polynomial time, even if finding the market equilibrium in intractable.
It will be a fun time, so make sure not to miss out!

CS Colloquium: Masahiro Ono (NASA JPL) - Robots in Space: How AI and Machine Learning are Revolutionizing Space Exploration
Thu, Oct 31, 2019 @ 02:00 PM - 03:20 PM

Conferences, Lectures, & Seminars
Speaker: Masahiro Ono, NASA JPL
Talk Title: Robots in Space: How AI and Machine Learning are Revolutionizing Space Exploration
Series: Computer Science Colloquium
Abstract: On the third planet of the Solar System, there is an ongoing revolution caused by a group of technologies collectively called as "AI," including, but not limited to, machine learning, optimal decision making, situation awareness, and autonomous navigation. The same revolution is taking off elsewhere in the Solar System, triggered by an advent of HPSC (high-performance spacecraft computing). This talk introduces ongoing research efforts to adapt and enhance latest AI technologies for future exploration missions to Mars, Europa, and Enceladus, such as resource-aware autonomous rover driving, on-board science interpretation, and autonomous descent into Enceladus's vents, which are believed to be connected to the subsurface ocean that may harbor extraterrestrial life.

Biography: Dr. Masahiro (Hiro) Ono is a Research Technologist at NASA Jet Propulsion Laboratory, California Institute of Technology. His broad interest is centered around the application of robotic autonomy to space exploration, with an emphasis on machine learning applications to perception, data interpretation, and decision making. Before joining JPL in 2013, he was an assistant professor at Keio University in Japan. He graduated from MIT with PhD in Aeronautics and Astronautics in 2012. Since 2017 he is the PI of a JPL-funded Strategic Research and Development task on the machine learning-based analytics for automated rover systems (MAARS). From 2015 he has led the development of machine learning- based Martian terrain classifier, which is used by MSL and Mars 2020 Rover missions. He was also the PI of a JPL-Caltech joint project on imitation learning-based planning from 2016 to 2018. He was awarded two NIAC Phase I studies: Comet Hitchhiker (2014) and Journey to the Center of Icy Moon (2016). Since 2019, he has been the Autonomy Lead of the EELS (Exobiology Extant Life Surveyor) project.

Conferences, Lectures, & Seminars
Speaker: Dr. Shengqiang Cai, University of California, San Diego
Talk Title: Soft Materials: from fundamental mechanics to applications
Abstract: In recent years, soft materials have been extensively explored in a myriad of engineering applications including wearable devices and soft robotics. In the talk, I will discuss some of our recent work on soft materials. The presentation will mainly contain two parts. In the first part, I will talk about recent progress made in our group on a newly emerging polymer: liquid crystal elastomer (LCE). I will show some examples of the applications of liquid crystal elastomer as artificial muscle in the design of soft robots. I will also discuss several very intriguing phenomena associated with the large deformation and soft elasticity of liquid crystal elastomers. In the second part of the talk, I will discuss the challenges of studying the mechanics of soft materials. Electromechanical instabilities of dielectric elastomer balloons and nonlinear instability of an everted tube will serve as two examples.
Biography: Professor Shengqiang Cai is currently an associate professor in the Department of Mechanical and Aerospace Engineering and Materials Science and Engineering program at the University of California, San Diego. He obtained his Ph.D. degree from Harvard University in 2011. After graduating from Harvard, he spent one year as postdoc at MIT. His research is mainly focused on mechanics of materials, especially soft materials and active materials. He received NSF CAREER award in 2016.

MASCLE Machine Learning Seminar: Joan Bruna (NYU) - On (Provably) Learning with Large Neural Networks

Talk Title: On (Provably) Learning with Large Neural Networks
Series: Machine Learning Seminar Series hosted by USC Machine Learning Center
Abstract: Virtually all modern deep learning systems are trained with some form of local descent algorithm over a high-dimensional parameter space. Despite its apparent simplicity, the mathematical picture of the resulting setup contains several mysteries that combine statistics, approximation theory and optimization, all intertwined in a curse of dimensionality.
In order to make progress, authors have focused in the so-called 'overparametrised' regime, which studies asymptotic properties of the algorithm as the number of neurons grows. In particular, neural networks with a large number of parameters admit a mean-field description, which has recently served as a theoretical explanation for its favorable training properties. In this regime, gradient descent obeys a deterministic partial differential equation (PDE) that converges to a globally optimal solution for networks with a single hidden layer under appropriate assumptions.
In this talk, we will review recent progress on this problem, and argue that such framework might provide crucial robustness against the curse of dimensionality. First, we will describe a non-local mass transport dynamics that leads to a modified PDE with the same minimizer, that can be implemented as a stochastic neuronal birth-death process, and such that it provably accelerates the rate of convergence in the mean-field limit. Next, such dynamics fit naturally within the framework of total-variation regularization, which following [Bach'17] have fundamental advantages in the high-dimensional regime. We will discuss a unified framework that controls both optimization, approximation and generalisation errors using large deviation principles, and discuss current open problems in this research direction.
