Boltzmann softmax operator
WebJul 1, 2024 · 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 ... WebFurthermore, when using the Boltzmann softmax operator in the Expected Sarsa update, for the expectation of the value in the next state, this operation is not guaranteed to be a non-expansion (Littman, 1996; Littman & Szepesvári, 1996). As mentioned earlier, mellowmax operator was designed to fix this non-expansion issue (Asadi & Littman, 2024),

In this work, we study a differentiable softmax operator that, among other properties, is a non-expansion ensuring a convergent behavior in learning and planning. We introduce a variant of SARSA ...
Weblearning. 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.

WebAlthough the state-of-the-art Twin Delayed Deep Deterministic Policy Gradient (TD3) algorithm mitigates the overestimation issue, it can lead to a large underestimation bias. In this paper, we propose to use the Boltzmann softmax operator for value function estimation in continuous control. We first theoretically analyze the softmax operator in ...
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: is jan. 2 2023 a federal holidayWebOct 17, 2024 · The Boltzmann softmax operator is a natural value estimator and can provide several benefits.
