WebThe results show that a VDBE-Softmax policy can outperform ε-greedy, Softmax and VDBE policies in combination with on- and off-policy learning algorithms such as Q-learning and Sarsa. Furthermore, it is also shown that VDBE-Softmax is more reliable in case of value-function oscillations. Keywords. Adaptive Control; Markovian Decision Process

Weird results of Q-learning with Softmax - Cross Validated

Web2 days ago · I am building a neural network to be used for reinforcement learning using TensorFlow's keras package. Input is an array of 16 sensor values between 0 and 1024, and output should define probabilities for 4 actions. From how I understand softmax to work, the output should be an array of probabilities for each of my actions, adding up to 1.

WebOct 24, 2024 · Basically this means interpreting the softmax output (values within $(0,1)$) as a probability or (un)certainty measure of the model. (E.g. I've interpreted an object/area with a low softmax activation averaged over its pixels to be difficult for the CNN to detect, hence the CNN being "uncertain" about predicting this kind of object.) WebSoftmax can be thought of as a softened version of the argmax function that returns the index of the largest value in a list.

WebJun 2, 2024 · low temperature softmax probs : [0.01,0.01,0.98] high temperature softmax probs : [0.2,0.2,0.6] Temperature is a bias against the mapping. Adding noise to the output. The higher the temp, the less it's going to resemble the input distribution. Think of it vaguely as "blurring" your output. Share Cite Improve this answer Follow WebApplying Bayes’ theorem reveals that the regular softmax is affected by the migration of the label distribution, and makes an estimate with a bias that causes the classifier computed by softmax regression to prefer that the sample belongs to the common class . It is also for this reason that high-frequency words may have an impact on the tail ...
