A Unified Analysis of Saddle Flow Dynamics: Stability and Algorithm Design
Pengcheng You, Yingzhu Liu, Enrique Mallada
This work examines the conditions for asymptotic and exponential convergence of saddle flow dynamics of convex-concave functions. First, we propose an observability-based certifica…
Invertibility of Discrete-Time Linear Systems with Sparse Inputs
Kyle Poe, Enrique Mallada, Rene Vidal
One of the fundamental problems of interest for discrete-time linear systems is whether its input sequence may be recovered given its output sequence, a.k.a. the left inversion pro…
Dissipative Gradient Descent Ascent Method: A Control Theory Inspired Algorithm for Min-max Optimization
Tianqi Zheng, Nicolas Loizou, Pengcheng You +1
Gradient Descent Ascent (GDA) methods for min-max optimization problems typically produce oscillatory behavior that can lead to instability, e.g., in bilinear settings. To address…
A Market Mechanism for a Two-stage Settlement Electricity Market with Energy Storage
Rajni Kant Bansal, Enrique Mallada, Patricia Hidalgo-Gonzalez
Electricity markets typically clear in two stages: a day-ahead market and a real-time market. In this paper, we propose market mechanisms for a two-stage multi-interval electricity…
Learning safety critics via a non-contractive binary bellman operator
Agustin Castellano, Hancheng Min, Juan Andrés Bazerque +1
The inability to naturally enforce safety in Reinforcement Learning (RL), with limited failures, is a core challenge impeding its use in real-world applications. One notion of safe…
