Title: Machine learning via Wasserstein statistical manifold

Abstract: In this talk, I start with reviewing several primal-dual structures in optimal transport (Wasserstein metric). Based on it, I will introduce the Wasserstein natural gradient in parametric statistical models. We pull back the L2-Wasserstein metric tensor in probability density space to parameter space, under which the parameter space become a Riemannian manifold. The gradient and Hamiltonian flows in parameter space are derived. When parameterized densities lie in 1D, we show that the induced metric tensor and gradient flow establish explicit formulas. Examples are presented to demonstrate its effectiveness in several machine learning problems.


Switching Time Optimization for Nonlinear Switched Systems

浙江大学玉泉校区智能系统与控制研究所二楼资料室, 9 a.m., July 2, 2018

Prof. Ryan Loxton, full professor in the School of Electrical Engineering, Computing, and Mathematics at Curtin University, Australia.

Abstract: Switched systems operate by switching among various different modes. Determining the optimal times at which the mode switches should occur is a fundamental problem in systems and control, with particular importance to the numerical solution of optimal control problems. This talk will discuss the switching time optimization problem for two classes of switched systems: those with time-dependent switching conditions (where the switches are directly controllable), and those with state-dependent switching conditions (where the switches occur when the system hits certain switching surfaces in the state space). It is widely believed that standard numerical optimization techniques struggle when applied to switching time optimization problems. In this talk we present new results showing that this challenge is over-stated; contrary to popular belief, switching times can in fact be optimized effectively using standard optimization methods. We verify this with a numerical example involving a switched system model for the production of 1,3-propanediol, an industrial polymer used in paints, adhesives, and lubricants.

An Optimal Control Approach to Deep Learning

An Optimal Control Approach to Deep Learning

浙江大学玉泉校区教九101演讲厅, 9:30 a.m., June 25, 2018

Dr. Qianxiao Li, Research Scientist at the Institute of High Performance Computing, A*STAR, Singapore and an adjunct assistant professor in the department of mathematics, National University of Singapore

Abstract: In this talk, we discuss a new approach to study the algorithmic and theoretical aspects of deep learning. In particular, the optimization of deep neural networks is recast as an optimal control problem, which is a classical problem that originates from the calculus of variations. Based on this viewpoint, we investigate the development of novel algorithms, as well as theoretical insights on generalization bounds of neural networks.

Bio of the speaker: Qianxiao Li is a research Scientist at the Institute of High Performance Computing, A*STAR, Singapore and an adjunct assistant professor in the department of mathematics, National University of Singapore. He graduated with a BA in Mathematics from University of Cambridge in 2010, and a PhD in applied mathematics from Princeton University in 2016. His main research interests include the theory and algorithms for deep learning, stochastic optimization and applications ofmachine learning to the physical sciences.

Visualizing Real World Flows

Visualizing Real World Flows

Professor Steve Wereley, Purdue University, Mechanical Engineering

  • 浙江大学紫金港校区西2-309

Particle Image Velocimetry (PIV) is a laboratory tool that many fluid mechanics professionals use to measure flows in their labs where experimental conditions can be perfectly controlled. However, quite often scientists need to know about flows in the real world. One example where fluid mechanics professionals must work in the field under non-ideal conditions is that of oil spilling into the environment. While the size of many oil spills is known because a fixed volume of oil has spilled out of a damage oil tanker, for many others, the size of the spill is not. For example, the Deepwater Horizon oil spill in the USA in 2010 occurred when the oil company lost control of an oil well and oil poured unrestrainedly into the Gulf of Mexico for more than 3 months (see picture below). In order to assess the amount of damage caused by the oil spill, Professor Wereley used quantitative flow visualization to estimate the size of the oil spill. This approach was shown to be much more accurate than other methods that were used to measure the size of the oil spill.

Abstract: Over last decade, small-size unmanned aerial vehicles (UAVs) have received unprecedented research interests and created extensive applications as well as market opportunities. Currently dominant UAV platforms, such as quadrotors and hexarotors, although exhibits great maneuverability (i.e. vertical takeoff and landing, hovering capability), is inherently energy inefficient by its flight mechanics. This drawback has increasingly limited their application in range- and/or endurance-demanding tasks such as surveying and mapping. Motivated by this, hybrid aerial vehicles such as tail-sitters, tilt-rotors, tilt-props, or dual-propulsion systems can transform between multirotor mode and fixed-wing mode, thus inheriting both benefits. Though having been actively explored in the aviation history, low-cost, small-size hybrid UAVs with increased intelligence and autonomy still poses a grand challenge. In this talk, I will present the development of a portable hybrid vertical takeoff and landing (VTOL) UAV. From a system point of view, three topics will be covered: design, modeling and control. Through the design, implementation and intensive tests, I will show how recent advances in low cost actuator (e.g. motor, propeller, ESCs), computation units and sensors have enabled the development of such small-size hybrid VTOL UAVs, and the arisen opportunities and challenges.

Abstract: Numerous physical processes are described by transport PDE-ODE interconnections. LTI systems with constant input delays is perhaps the most elementary class in this category, where the transport speed is constant and the boundary of the spatial domain is fixed, besides the plant being linear. For this class of systems, predictor feedback is now a well-known delay-compensating control design tool. The situation becomes dramatically more complex when, in addition to the ODE being nonlinear, the speed of propagation or the boundary of the domain is a nonlinear function of the overall infinite-dimensional state (i.e., of the PDE or the ODE state) of the system. For such interconnections, I will present predictor-feedback design ideas, which I will then illustrate with several application examples, including, traffic systems (where the transport speed is a nonlinear function of the PDE state), extruders for 3D printing (giving rise to a system with ODE state-dependent moving boundary), and metal rolling (where the transport speed is a nonlinear function of the ODE state).

Nikolaos Bekiaris-Liberis received the Ph.D. degree in Aerospace Engineering from the University of California, San Diego, in 2013. From 2013 to 2014 he was a postdoctoral researcher at the University of California, Berkeley and from 2014 to 2017 he was a research associate and adjunct professor at Technical University of Crete, Greece. Dr. Bekiaris-Liberis is currently a Marie Sklodowska-Curie Fellow at the Dynamic Systems & Simulation Laboratory, Technical University of Crete. He has coauthored the SIAM book Nonlinear Control under Nonconstant Delays. His interests are in delay systems, distributed parameter systems, nonlinear control, and their applications.

Dr. Bekiaris-Liberis was a finalist for the student best paper award at the 2010 ASME Dynamic Systems and Control Conference and at the 2013 IEEE Conference on Decision and Control. He received the Chancellor’s Dissertation Medal in Engineering from the University of California, San Diego, in 2014. Dr. Bekiaris-Liberis received the best paper award in the 2015 International Conference on Mobile Ubiquitous Computing, Systems, Services and Technologies. He is the recipient of a 2017 Marie Sklodowska-Curie Individual Fellowship Grant.
