This window pops up as soon as OpendTect has created or retrieved the train and test sets. In order to create a training set, the software must compute all selected attributes at all picked locations. This may take some time. The user will be notified when the data is collected. Acknowledging the notification will automatically start the training phase.
Training can be stopped and restarted with the Pause (Resume) button. Clear randomizes the weights of the current network. This implies that all training results are lost. The Clear option can be used when over fitting (see below) has occurred and the user wishes to restart training from scratch. The randomized network is then re-trained and the network is stopped before over fitting occurs. This can be done manually (pressing Pause) or by specifying a number in the number of training vectors field.
