WebbThe “Shannon entropy” is a concept introduced by Shannon (1948), where a measure of the uncertainty of occurrence of certain event, given partial information about the system, is proposed. In the context of molecular reconstruction, the Shannon entropy is defined as , and solving the reconstruction is posed as an optimization problem, (1) Webb6.1 Main properties of Shannon entropy Let Xbe a random variable taking values xin some alphabet with probabil-ities px = Prob(X= x). The Shannon entropy of Xis H(X) = ∑ x px ln 1 px and quanti es the average uncertainty about X.

Webbscipy.stats.entropy. #. Calculate the Shannon entropy/relative entropy of given distribution (s). If only probabilities pk are given, the Shannon entropy is calculated as H = -sum (pk * log (pk)). If qk is not None, then compute the relative entropy D = sum (pk * log (pk / qk)). This quantity is also known as the Kullback-Leibler divergence.
