Weird results of Q-learning with Softmax - Cross Validated

WebMar 14, 2024 · Value function estimation is an important task in reinforcement learning, i.e., prediction. The Boltzmann softmax operator is a natural value estimator and can provide several benefits. However, it does not satisfy the non-expansion property, and its direct use may fail to converge even in value iteration.

WebQ-learning [6] is an off-policy temporal difference (TD) [22] learning technique. With an off-policy learning method, the agent follows a behavioral policy and at the same time learns about the optimal Q-function. If the agent visits all state-action pairs an inﬁnite number of times, Q-learning converges to the optimal Q-function [23].
