Plot softmax
WebbSoftmax is probability matching strategy, which means that the probability of each action being chosen is dependent on its Q-value so far. Formally, softmax chooses an action because on the Boltzman distribution for that action: e Q ( a) / τ ∑ b = 1 N e Q ( b) / τ WebbCompute the softmax function. The softmax function transforms each element of a collection by computing the exponential of each element divided by the sum of the exponentials of all the elements. That is, if x is a one-dimensional numpy array: softmax(x) = np.exp(x)/sum(np.exp(x)) Parameters: xarray_like Input array.
