Learning Neural Representations for Network Anomaly Detection

1 code implementation IEEE Transactions on Cybernetics 2019 Van Loi Cao, Miguel Nicolau, and James McDermott

Our approach is to introduce new regularizers to a classical autoencoder (AE) and a variational AE, which force normal data into a very tight area centered at the origin in the nonsaturating area of the bottleneck unit activations.

Improving Fitness Functions in Genetic Programming for Classification on Unbalanced Credit Card Datasets

no code implementations11 Apr 2017 Van Loi Cao, Nhien-An Le-Khac, Miguel Nicolau, Michael ONeill, James McDermott

We examine two fitness functions from previous studies and develop two new fitness functions to evolve GP classifier with superior accuracy on the minority class and overall.
