WebbIn probability theory and statistics, the Jensen–Shannon divergence is a method of measuring the similarity between two probability distributions.It is also known as information radius (IRad) or total divergence to the average. It is based on the Kullback–Leibler divergence, with some notable (and useful) differences, including that it … WebbThe channel capacity C can be calculated from the physical properties of a channel; for a band-limited channel with Gaussian noise, using the Shannon– Hartley theorem. For every discrete memory less channel, the channel capacity has the following property. For any ε > 0 and R < C, for large enough N, there exists a code of darpa track house
