A Pattern Recognition System Using Evolvable Hardware

We describe a high-speed pattern recognition system using Evolvable Hardware (EHW), which can change its own hardware structure by genetic learning in order to adapt best to the environment. The purpose of the system is to show that EHW can work as a recognition device with such robustness for the noise as seen in the recognition systems based on neural networks. The advantage of EHW compared with a neural network is the high processing speed and the readability of the learned result. The readability means that the result is understandable in terms of Boolean functions. In this paper, we describe the architecture, the learning algorithm and the experiment on the pattern recognition system using EHW.
