WebA novel proof of convergence of Q-learning with linear function approximation that requires significantly less stringent conditions that those currently available in the literature; A … WebDeveloping Q-learning with linear function approximation In the previous recipe, we developed a value estimator based on linear regression. We will employ the estimator in Q-learning, as part of our FA journey. As we have seen, Q-learning is an off-policy learning algorithm and it updates the Q-function based on the following equation:

You are free to choose how the action part maps to values in the feature vector. Two simple options are: { l e f t, r i g h t } → { [ 1, 0], [ 0, 1] } i.e. one-hot coding. { l e f t, r i g h t } → ... burny serial numbers
Q-Learning with Linear Function Approximation
WebAug 31, 2024 · Using linear function approximators with Q-learning usually requires (except in very specific cases) compute a set the features, so your approximator is linear with respect to the extracted features, no the … Weba linear function approximation setting [4] (also see [47, 43, 19]). There has also been progress for general linear function approximation: sufficient conditions for convergence of the basic Q-learning algorithm (1) was obtained in [32], with finite-n bounds appearing recently in [13], and stability WebMar 30, 2024 · Let’s consider the simplest case, using linear action-value function approximation. We build a feature vector to represent state and actions: These features explain the entire state-action space. We do this by building a linear combination of features, but we can also use a more sophisticated system like a neural network. burny shop
