Can we efficiently find a local minimum of a nonconvex continuous optimization problem? We give a rather complete answer to this question for optimization problems defined by polynomial data. In the unconstrained case, the answer remains positive...

At the heart of the transition to a zero-carbon power system is a technological paradigm shift from conventional generation to renewable generation connected to the grid via power electronics. In this context, the literature and public debate mostly...

In control theory, complicated dynamics such as systems of (nonlinear) differential equations are mostly controlled to achieve stability and to optimize a cost. In formal synthesis, simple systems such as finite state transition graphs modeling...

This talk will focus on systems-theoretic and control theory tools that help characterize the responses of nonlinear systems to external inputs, with an emphasis on how network structure constrains finite-time, transient behaviors. Of interest are...

We begin by studying the problem of learning a linear system model from the observations of M clients. The catch: Each client is observing data from a different dynamical system. This work addresses the question of how multiple clients...

Linear dynamical systems are the canonical model for time series data. They have wide-ranging applications and there is a vast literature on learning their parameters from input-output sequences. Moreover they have received renewed interest because...

In the contemporary era, Sustainable Development Goals (SDGs) serve as the backbone of global efforts to ensure a future that harmonizes environmental conservation, social equity, and economic growth. One of the critical challenges facing these...

Many agent-based systems interacting with their environments are well-modeled by Markov Decision Processes (MDPs). MDPs also form the ``model ‘’ framework for many learning strategies such as reinforcement learning. We focus on policy design to...

Decision-making in dynamic uncertain environments with multiple agents having possibly misaligned objectives arises in many disciplines and application domains, including control (particularly networked control, such as control and operation of...

In this talk we will discuss estimation entropy for continuous-time nonlinear systems, which is a variant of topological entropy formulated in terms of the number of functions that approximate all system trajectories up to an exponentially decaying...

A recursive, analytic, real-time state estimation algorithm for linear and nonlinear systems, referred to as the Multivariate Cauchy Estimator (MCE), is presented. The algorithm enables robust state estimation performance for applications where the...

We consider a version of a policy optimization in reinforcement learning where one has to learn rewards through human feedback. We study the sample complexity of this algorithm and compare it to the sample complexity of an algorithm where the...

I survey recent advances on contraction theory for dynamical systems, as a robust, computationally-friendly and modular stability theory. Starting from basic notions, I will present novel theoretical properties and examples of contracting dynamics,...
