چکیده

This paper investigates the dynamics of batch learning in multilayer neural networks. First, we present experimental results on the behavior in the steepest descent learning of multilayer perceptrons and linear neural networks. From the results of both models, we see that strong overtraining, the increase of generalization error, occurs in overrealizable cases where the target function is realized by a smaller number of hidden units than the model. Next, under the assumption of asymptotical limit, we mathematically prove the existence of overtraining in overrealizable cases of linear neural networks. From this theoretical analysis, we know that the overtraining is not a feature observed in the nal stage of learning , but it occurs in the intermediate interval of time and forms the global shape of a learning curve.

Effect of Batch Learning in Multilayerneural

This paper discusses batch gradient descent learning in mul-tilayer networks with a large number of statistical training data. We emphasize on the diierence between regular cases, where the prepared model has the same size as the true function , and overrealizable cases, where the model has surplus hidden units to realize the true function. First, experimental study on multilayer perceptrons an...
