Pythia

From Runtime Software:

Pythia is a program for the development and design of Neural Networks. Neural Networks are used to detect hidden relations in a set of patterns, e.g. stock market data or weather data.

Pythia features Backpropagation Networks. The network parameters (“Weights�) are initially set to random value. During the “Training Phase� the actual output of the network is compared with the desired output and the error propagated back toward the input of the network.

Pythia allows you to import data from different file formats or from spreadsheet programs like Microsoft Excel. You can design and train Neural Networks. Both, data and networks can easily be stored on disk.
