demtrain

Purpose

Demonstrate training of MLP network.

Synopsis

demtrain

Description

demtrain brings up a simple GUI to show the training of an MLP network on classification and regression problems. The user should load in a dataset (which should be in Netlab format: see datread), select the output activation function, the number of cycles and hidden units and then train the network. The scaled conjugate gradient algorithm is used. A graph shows the evolution of the error: the value is shown max(ceil(iterations / 50), 5) cycles.

Once the network is trained, it is saved to the file mlptrain.net. The results can then be viewed as a confusion matrix (for classification problems) or a plot of output versus target (for regression problems).
