Abstract

There is tried 2-layer perceptron in classifying turn-distorted objects at acceptable classification error percentage. The object model is a letter of English alphabet, which is monochrome 60-by-80-image. Neither training 2-layer perceptron with pixel-distorted images, nor with turn-distorted images makes it classify satisfactorily. Therefore in classifying turn-distorted images a 2-layer perceptron performance might be improved via training under distortion modification. The modified distorted images for the training set are suggested as mixture of turn-distorted and pixel-distorted images. Thus the training set is formed of pixel-distorted turned images on the 26 alphabet letters pattern. A performance improvement is revealed when there are passed much more training samples through 2-layer perceptron. This certainly increases traintime, but instead 2-layer perceptron can classify either of pixel-distorted images and pixel-distorted turned images. At that the trained 2-layer perceptron is about 35 times faster than neocognitron in classifying objects of the considered medium format.
