Webbrecover the Shannon formula (2) by using L’Hopital’s rule.) Starting from the R´enyi entropy, one can define R´enyi information, I α = H α[X]+H α[Y]−H α[X,Y] and so forth, through the rest of the formal structure of information theory. Crucially, however, a lot of the connections to coding theory, to statistics, and Webb19 juni 2024 · Entropy is maximized (and predictability minimized) when all outcomes are equally likely. Shannon Entropy, (H) is given by the following equation: [H = -\sum_ {i=1}^np_i\log_2 p_i] Where (n) is the number of possible outcomes, and (p_i) is the probability of the (i^ {th}) outcome occurring.
