Pattern Recognition System using Evolvable Hardware

We have developed a high-speed pattern recognition system using evolvable hardware (EHW) in 1996. The purpose of the system is to show that recognition devices based on EHW are possible and that they have the same robustness against noise as devices based on an artificial neural network (ANN). The advantage of EHW compared with ANN is the high processing speed and the readability of the learned result. We confirmed the advantage with an experiment on recognizing the binary patterns of 8 x 8 pixels. We also compared the processing speed of the pattern recognition system with two types of fastest class ANN dedicated hardware. The recognition speed of the EHW was the fastest; 1.7 times as fast as that of CNAPS, and 9.2 times as fast as that of MY-NEUPOWER.
