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

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

A Decoupling Principle in Stochastic Optimal Control and Its Implications

February 28, 2020 - 11:15 AM TSRB auditorium Suman Chakravorty Texas A&M University Abstract The problem of Stochastic Optimal Control is ubiquitous in Robotics and Control since it is the fundamental formulation for decision-making under uncertainty. The answer to the problem can be computed by solving an associated Dynamic Programming (DP) problem. Unfortunately, the DP … Continue reading A Decoupling Principle in Stochastic Optimal Control and Its Implications

On strategic information transmission in Cyber-Socio-Physical Systems

February 14, 2020 - 11:15 AM TSRB auditorium Cedric Langbort University of Illinois at Urbana Champaign Abstract We consider situations in which better informed agents must decide which message to transmit to a decision-making receiver, so as to influence the decision in their favor. Such scenarios, some versions of which have been considered earlier in … Continue reading On strategic information transmission in Cyber-Socio-Physical Systems
