Webb7 jan. 2024 · Entropy can be computed for a random variable X with k in K discrete states as follows. H (X) = -sum (each k in K p (k) * log (p (k))) That means the negative of the sum of the probability of each event multiplied by the log of the probability of each event. Like information, the log () function implements base-2 and the units are bits. Webb10 mars 2024 · Shannon entropy can be calculated based upon the observed probability that a particular event occurs.
