Webe. In information theory, the entropy of a random variable is the average level of "information", "surprise", or "uncertainty" inherent to the variable's possible outcomes. Given a discrete random variable , which takes values in the alphabet and is distributed according to : where denotes the sum over the variable's possible values. http://micro.stanford.edu/~caiwei/me334/Chap7_Entropy_v04.pdf garden city fire marshal

Webtions is the relative entropy, also sometimes called the Kullback-Leibler divergence. Deﬁnition The relative entropy between two probability distributions p(x) and q(x) is given by D(p(x) q(x)) = X x p(x)log p(x) q(x). (30) The reason why we are interested in the relative entropy in this section is because it is related WebThere is a 50% probability of both outcomes; then, in such scenarios, entropy would be high. This is the essence of entropy in machine learning. Mathematical Formula for Entropy.
