Segura Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires ABSTRACT This article presents a promising new gradient-based backpropagation algorithm for multi-layer feedforward networks. Considering both effectiveness and efficiency,. Two of these are the Adaptive learning rate Backpropagation algorithm [2], referred to as gda, and the Resilient Backpropagation [10], known as Rprop. The performance and evaluations were performed using the NSL-KDD anomaly intrusion detection dataset. ﬁne-tuning, using the standard backpropagation algorithm, then adjusts the features in every layer to make them more useful for discrimination. Since it's a lot to explain, I will try to stay on subject and talk only about the backpropagation algorithm.
