Thesis "Comparison of various methods of training the neural networks" Using Mathematica computational software package I tried to show how various ANN training algorithms perform using two different types of optimization problems. I was evaluating not only the speed of error function convergence but also the quality of generalization achieved by the neural networks. Methods of learning tested were: basic back-prop, backprop with momentum, competitive back-prop, and others.
