SUMMARY
Object classification problem is considered, where neocognitron and multilayer perceptron may be applied. As neocognitron, solving almost any classification problem, performs too slowly and expensively, then for recognizing shifted monochrome images there is attempted the 2-layer perceptron, being fast only for pixel-distorted monochrome images, though. Having assumed the original images set of 26 monochrome 60-by-80-images of the English alphabet letters, there is formulated the task to clear out whether the 2-layer perceptron is capable to ensure high performance in classifying shifted monochrome images. Thus it is disclosed that the 2-layer perceptron performs as the good classifier of shifted monochrome images, when in training its input is fed with training samples from shifted images, being pixel-distorted. For this, however, it may need more passes of training samples through the 2-layer perceptron, but nevertheless the total traintime will be shorter than for training the 2-layer perceptron with only pixel-distortion-free shifted monochrome images.
