15.31. Internals of the Trained Network

Applies to: NeuralTools 5.5 and newer

Can I see the internals of the trained network or the actual equation that NeuralTools develops?

For a neural net, no "equation" is reported. The details of how a neural net computes the predictions would often be very complex, especially for PN/GRN nets.

Beginning with 5.5, NeuralTools attempts linear regression in addition to training a neural net. If the linear function makes better predictions on the testing set, then the linear function is used instead of a neural net. In this case, the linear function intercept and coefficients are listed in the report. An example installs with NeuralTools:
