Initial learning process of the BP, which can influence the performance of learning in multiclass classification problems, is analyzed. Also, the weights decreasing phenomena in the initial stage of learning are investigated. On the basis of this analysis, a new initialization method is proposed. ...

Multi-layer perceptrons (MLP) make powerful classifiers that may provide superior performance compared with other classifiers, but are often criticized for the number of free parameters. Most commonly, parameters are set with the help of either a validation set or cross-validation techniques, but the...
These techniques demonstrate high efficiency when combined with a multilayer perceptron (MLP), as reflected in the performance of our multiclass classification experiments. The effectiveness of the proposed model is evaluated using three widely studied datasets: NSL-KDD, UNSW-NB15, and CICIDS2017. ...
