The Principle of Maximum Entropy: For a probability mass function p = (Pi, € S) on a countable set S, the entropy defined by h(p) = -∑(Pi * log Pi) for i in S. For a continuous probability density function f (x) on the interval [a, b], the entropy defined by h(f) = -∫(f(x) * log f(x)) dx.In the definition of entropy, log T is understood to be zero whenever T = 0. The entropy of a probability distribution can be seen as a measure of the amount of ignorance in the distribution. The principle
