Explanation of entropy
WebNov 1, 2013 · 29. From a modern point of view, the paradigmatic definition of entropy is that it is a number associated to a probability distribution over a finite sample space. Let N be the size of your sample space and let p1, p2, …, pN be the probabilities of the events. Then the entropy of the probability distribution is defined to be H = N ∑ i = 1 ...
