Genetic Programming for Classification with Unbalanced Data

Bhowan, Urvesh (Victoria University of Wellington, 2012)

In classification,machine learning algorithms can suffer a performance bias when data sets are unbalanced. Binary data sets are unbalanced when one class is represented by only a small number of training examples (called ...
Problem Decomposition and Adaptation in Cooperative Neuro-Evolution

Chandra, Rohitash (Victoria University of Wellington, 2012)

One way to train neural networks is to use evolutionary algorithms such as cooperative coevolution - a method that decomposes the network's learnable parameters into subsets, called subcomponents. Cooperative coevolution ...
