Shannon-Fano coding (SFC) and Huffman coding (HC) are classic and well-known algorithms, but still in use today. The search for the simplest example that proves HC overperforms SFC is still of interest. The problem is not as trivial as i... M Breazu,D Morariu,R Cretulescu,... - ...
This is the first time information-theoretic methods have been used as the basis for solving the suffix sorting problem. Keywords: suffix sorting; suffix arrays; suffix tree; Shannon-Fano-Elias codes; source coding1. Introduction The suffix array provides a compact representation of all the n ...
For instance, the Shannon coding (and Shannon–Fano) sorts the symbols of an alphabet according to their probabilities, assigning smaller binary self-delimited sequences to symbols that appear more frequently. Such methods form the base of many, if not most, commonly used compression algorithms. ...

Since the vector-skew Jensen divergence is an f-divergence, we easily obtain Fano and Pinsker inequalities following [32], or reverse Pinsker inequalities following [33,34] (i.e., upper bounds for the vector-skew Jensen divergences using the total variation metric distance), data processing ineq...
