Risk Estimation in a Markov Cost Process: Lower and Upper Bounds
Gugan Thoppe, L. A. Prashanth, Sanjay Bhat
We tackle the problem of estimating risk measures of the infinite-horizon discounted cost within a Markov cost process. The risk measures we study include variance, Value-at-Risk (…
Online Learning with Adversaries: A Differential-Inclusion Analysis
Swetha Ganesh, Alexandre Reiffers-Masson, Gugan Thoppe
We introduce an observation-matrix-based framework for fully asynchronous online Federated Learning (FL) with adversaries. In this work, we demonstrate its effectiveness in estimat…
Policy Gradient with Tree Expansion
Gal Dalal, Assaf Hallak, Gugan Thoppe +2
Policy gradient methods are notorious for having a large variance and high sample complexity. To mitigate this, we introduce SoftTreeMax -- a generalization of softmax that employs…
