Q learning softmax

WebSoftmax can be thought of as a softened version of the argmax function that returns the index of the largest value in a list. How to implement the softmax function from scratch in … 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.
