Tensorflow.js implementation of DQN in Reinforcement Learning — “Practice what you know, and it will help to make clear what now you do not know” Rembrandt Overview The Deep Q-Network proposed by Mnih et al. [2015] is a jumpstart and building point for many deep reinforcement learning algorithms. …

Pushing the limits of MC method with special cases and practical examples. — Monte Carlo, as well as Dynamic Programming, Temporal Difference are the main methods for starters in Reinforcement Learning. Monte Carlo First, let’s have a brief reminder of what is Monte Carlo method. Monte Carlo is an algorithm that generates paths (which constitutes an episode) based on the current policy which usually splits between…

Introduction to CFR and implementation of the Tic-Tac-Toe game — “We should regret our mistakes and learn from them, but never carry them forward into the future with us.” Lucy Maud Montgomery Learning from regrets is what Counter Factual Minimization is all about. The notion of “regret” is introduced in the article “Introduction to Regret in Reinforcement Learning”. However, it…
