A Telephone Number Corrector Using a Counterpropagation Network

This paper describes the implementation of a system that reminds the user of the telephone number of a given list, even if the user only remembers part of it, or if the given number contains a series of exchanged digits. The system’s input consists of a telephone number (composed by digits from 0 to 9), containing from zero up to several generic digits (asterisks, in this case). The system processes the input and returns the selected telephone number among all the learned telephone numbers. In this implementation autoassociative memories have been used.
