Jensen-shannon mutual information

The Jensen–Shannon divergence is the mutual information between a random variable associated to a mixture distribution between and and the binary indicator variable that is used to switch between and to produce the mixture. Let be some abstract function on the underlying set of events that discriminates well between events, and choose the value of according to if and according to if , where is equiprobable. That is, we are choosing according to the probability measure , and its distr… WebThe Jensen-Shannon Objective¶ Since we do not concern the precise value of mutual information, and rather primarily interested in its maximization, we could instead optimize …
