The link between cognition and control must … Continue reading The Rational Selection of Goal Operations and the Integration of Search Strategies with Goal-Driven Marine Autonomy

Objective Learning for Autonomous Systems

April 9, 2021 - 2:00 pm in Bluejeans: https://bluejeans.com/851024140 Shaoshuai Mou Purdue University Abstract Autonomous systems especially those driven under optimal control are usually associated with objective functions to describe their goals/tasks in specific missions. Since they are usually unknown in practice especially for complicated missions, learning such objective functions is significant to autonomous systems … Continue reading Objective Learning for Autonomous Systems

Fastest Identification in Linear Systems

March 19, 2021 - 09:00 am Alexandre Proutiere KTH, Stockholm, Sweden Abstract Abstract: We report recent results on two classical inference problems in linear systems. (i) In the first problem, we wish to identify the dynamics of a canonical linear time-invariant systems $x_{t+1}=Ax_t+\eta_{t+1}$ from an observed trajectory. We provide system-specific sample complexity lower bound satisfied … Continue reading Fastest Identification in Linear Systems

Abstract Learning-based control paradigms have seen many success stories with various robots and co-robots in recent years. However, as these robots prepare to enter the real world, operating safely in the presence … Continue reading Safe Learning and Control with L1 Adaptation

Enabling Human-Aware Automation: A Dynamical Systems Perspective on Human Cognition

November 13, 2020 - 11:00 AM https://bluejeans.com/758301136?src=join_info Neera Jain Perdue University Abstract Across many sectors, ranging from manufacturing to healthcare to the military theater, there is growing interest in the potential impact of automation that is truly collaborative with humans. Realizing this impact, though, rests on first addressing the fundamental challenge of designing automation to … Continue reading Enabling Human-Aware Automation: A Dynamical Systems Perspective on Human Cognition

Three Problems in Mathematical Oncology

October 16, 2020 - 03:15 PM https://bluejeans.com/998437780?src=join_info Paul K. Newton University of Southern California Abstract I will introduce three problems in mathematical oncology all of which involve nonlinear dynamics and control theory. First, I will describe our work using Markov chain models to forecast metastatic progression. The models treat progression as a (weighted) random walk … Continue reading Three Problems in Mathematical Oncology

Stochastic Approximation: Some New Wine in Old Bottle

October 06, 2020 - 11:00 AM https://bluejeans.com/151197147 Vivek S. Borkar Indian Institute of Technology Bombay Abstract This talk will give an overview of old and new results and directions in stochastic approximation algorithms, broadly split into basic theory, variants, and applications. Central to all this will be the 'o.d.e' (for 'Ordinary Differential Equations') approach to … Continue reading Stochastic Approximation: Some New Wine in Old Bottle

Mean Field Differential Games with Elements of Robustness

September 04, 2020 - 02:00 PM https://bluejeans.com/671208563?src=join_info Tamer Basar University of Illinois, Urbana Abstract Perhaps the most challenging aspect of research on multi-agent dynamical systems, formulated as non-cooperative stochastic differential/dynamic games (SDGs) with asymmetric dynamic information structures is the presence of strategic interactions among agents, with each one developing beliefs on others in the absence … Continue reading Mean Field Differential Games with Elements of Robustness
