WebNov 24, 2024 · REINFORCE belongs to a special class of Reinforcement Learning algorithms called Policy Gradient algorithms. A simple implementation of this algorithm would involve creating a Policy: a model that takes a state as input and generates the probability of taking an action as output. A policy is essentially a guide or cheat-sheet for the agent ... assassin\\u0027s ri
