Article: Massachusetts Inventor Develops Symbol Sequence Encoding/Decoding Model

ALEXANDRIA, Va., Sept. 6 -- Ratko V. Tomic of Lexington, Mass., has developed a symbol sequence encoding/decoding model.

According to the U.S. Patent & Trademark Office: "Entropy encoders and decoders employ an entropy-pump operation. The entropy-pump operation includes classifying blocks of the input sequence's symbols in accordance with the probabilities of occurrence of those blocks' values."

An abstract of the invention, released by the Patent Office, said: "Entropy coding an output component that represents the sequence of classes to which the blocks belong tends to be profitable, because that component has an entropy density less than that of the input sequence. In contrast, ...
