A pattern identification system using linear decision functions

This paper is concerned with application of linear decision functions to the pattern identification problem and describes an experimental pattern recognition system for the magnetic ink character font now used in the banking industry. The system is based on a linear decision function determined by means of a variant of an "adaptive training" technique due to Rosenblatt. The system has been partially implemented (in part, through simulation with aid of a digital computer and, in part, by hardware) and experimental results in using the system are reported.
