Fast Pruning Using Principal Components
... In recent years, several methods have been proposed. Skeletonization (Mozer and Smolensky, 1989) removes the neurons that have the least eect on the output error. This is costly and does not take into account correlations between the neuron activities. Eliminating small weights does not properly ac ...
