The program for the creation and use of three-layer perceptrons with arbitrary and an equal number of inputs, outputs and neurons in each layer. To create a network in the sampling program are introduced and after clicking "create a network" and you will create a learning network Backpropagation. After creating a network it can be saved, it can be used. Networks can be used for different purposes such as: forecasting the dynamics of exchange rates, the analysis of website visitor statistics, market analysis, forecasting the results of games, etc. For normal learning and results in the sample should be added to a sufficient amount of accurate information and provide the program enough time to train the network. The program has the ability to set limitations on the duration of education and training for a long time if it is delayed interrupted. Also, any time you can interrupt the training came out of the program. Output from the program can be done by pressing the X in the upper right corner or by selecting the appropriate menu item. Withdrawal shall be without pay and notice. Neural networks can find many useful applications!
