Boltzmann softmax operator
WebarXiv.org e-Print archive 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:

We then present a new softmax operator that is similar to the Boltzmann operator yet is a non-expansion. We prove several critical properties of this new operator, introduce a new softmax policy, and present empirical results. 2. Boltzmann Misbehaves We first show that boltz can lead to problematic behavior. To this end, we ran SARSA ...
WebSelection is the stage of a genetic algorithm or more general evolutionary algorithm in which individual genomes are chosen from a population for later breeding (e.g., using the crossover operator).. A selection procedure used early on may be implemented as follows: . The fitness values that have been computed (fitness function) are normalized, such that … WebThe Boltzmann softmax operator is the most commonly used softmax operator in this setting, but we show that this operator is prone to misbehavior.

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 …
