Structure Matters: Dynamic Policy Gradient

Sara Klein, Xiangyuan Zhang, Tamer Başar +2

In this work, we study γ-discounted infinite-horizon tabular Markov decision processes (MDPs) and introduce a framework called dynamic policy gradient (DynPG). The framework dire…

Almost sure convergence rates of stochastic gradient methods under gradient domination

Simon Weissmann, Sara Klein, Waïss Azizian +1

Stochastic gradient methods are among the most important algorithms in training machine learning problems. While classical assumptions such as strong convexity allow a simple analy…

Beyond Stationarity: Convergence Analysis of Stochastic Softmax Policy Gradient Methods

Sara Klein, Simon Weissmann, Leif Döring

Markov Decision Processes (MDPs) are a formal framework for modeling and solving sequential decision-making problems. In finite-time horizons such problems are relevant for instanc…
