Title: Innovations of Toru Oki
Introduction
Toru Oki is a notable inventor based in Allendale, NJ, who has made significant contributions to the field of neural networks and pattern recognition. With a total of six patents to his name, Oki has developed innovative methods that enhance the efficiency and accuracy of pattern searching.
Latest Patents
One of Oki's latest patents is a pattern searching method using neural networks and correlation. This method combines the quickness and adaptiveness of neural networks with the accuracy of the mathematical correlation approach. Images are divided into small sub-images, which are presented to the trained neural network. The neural network selects sub-images that may contain the pattern or partial pattern and provides the approximate location of the pattern. This allows the selected sub-images to be adjusted to contain the complete pattern. Desired patterns can be located by measuring the new sub-images' correlation values against the reference models in a small area. Experiments show that this superior method is able to find the desired patterns much faster than traditional pattern searching methods that use only correlation.
Another significant patent is the training method for a neural network. In this method, a neural network designed to recognize a particular character is supplied with initial tap weights for a first hidden node, which are an image of the character to be recognized. The additive inverse of this set of weights is used as the tap weights for a second hidden node. If a third node is used, it is initialized with random noise. The network is then trained with back propagation, enhancing its ability to recognize characters effectively.
