An Alternative Softmax Operator for Reinforcement Learning

WebHowever, the Boltzmann softmax operator, boltz , is not a non-expansion (Littman,1996), and so, its ﬁxed point may not be unique. Note that we can relate GVI to SARSA by noticing that SARSA update can be thought of as a stochastic implementation of GVI update. For example, under a Boltzmann softmax policy we have: Web2.1 The Mellowmax Operator and Deep Reinforcement Learning The Mellowmax operator [1] is an alternative softmax operator deﬁned as: mm!(x) = log(1 n P n i=1 exp(!x i))!; (1) where x is an input vector of nreal numbers, and !is a temperature parameter.1 Mellowmax is a non-expansion, which ensures convergence to a unique ﬁxed point.

WebBoltzmann "soft max" distribution. 1) Each p ( i) is a number between 0 and 1, no matter what the fitness is (positive or negative). This scheme does not require that fitness has to be positive. 2) The sum of all the p ( i) 's is 1, i.e. this is a probability distribution. If two items have same fitness, they have same probability of being picked. WebJan 28, 2024 · Abstract: Soft-greedy operators, namely $\varepsilon$-greedy and softmax, remain a common choice to induce a basic level of exploration for action-value methods in reinforcement learning. These operators, however, have a few critical limitations. In this work, we investigate a simple soft-greedy operator, which we call resmax, that takes …
