Webb15 feb. 2024 · To extract this feature, we used the Shannon entropy, defined as: I ( p −, C) = − ∑ i = 1 C p i l o g 2 ( p i) where p − is a probability distribution and C is the number of available characters that is dependent on the chosen encoding in … WebbThe Shannon entropy quantifies the uncertainty (entropy or degree of surprise) associated with this prediction. It is most often calculated as follows: where pi is the proportion of characters belonging to the i th type of letter in the string of interest.
