Similar principles appear in the design of some of the current generation of artificial neural nets.
Although some researchers continued to develop these ideas, they went out of fashion for many years and have only recently begun to attract renewed attention. Part of the reason for preparing this page is to encourage more interest in 'cognitive economy' and principles of information compression which have been recognised by neurophysiologists for some time, especially the importance of inhibition in nervous tissue as a means of extracting redundancy from information. Concepts of economical coding in the nervous system have been a theme in Horace Barlow 's work for many years. Principles of Minimum Length Encoding, and their possible role in explaining how a child may learn his or her first language, have been examined in a program of research on Language Learning as Compression .
