WebJan 1, 2013 · The cross-entropy method is a versatile heuristic tool for solving difficult estimation and optimization problems, based on Kullback–Leibler (or cross-entropy) minimization. As an optimization method it unifies many existing population-based optimization heuristics. Webbetween two sampling distributions. The CE method is particularly useful for the estimation of rare-event probabilities. The method can also be used to solve a diverse range of …

This paper studies the constrained reinforcement learning (RL) problem without assumptions about prior knowledge of the system dynamics and the constraint function. WebJul 4, 2024 · Cross-Entropy Method is a simple algorithm that you can use for training RL agents. This method has outperformed several RL techniques on famous tasks including the game of Tetris⁴. You can use this as a baseline³ before moving to more complex RL algorithms like PPO, A3C, etc. common cybersecurity control frameworks
