Paralysed network

Fig. 44.16. (a) Ideal performance curve of a MLF network. The solid line represents the training set the dashed line represents the monitoring set. (b) overtraining of the network begins at point A. (c) Paralysed network, (d) Performance curve of an MLF network for which the training and control samples represent different models. 

In Fig. 44.16c the performance behaviour of a paralysed network is shown. The normal decrease of the NSE stops too soon and the NSE remains too high to be acceptable. The paralysation of the network occurs when the weighted input value,...
