Maximizing competition in a biologically plausible neural network
The goal of this work is increasing competition among the neurons of a one layer feed-forward neural network. The feed-forward weights from input to the cells are learnt using a Hebbian based learning rule and the weights between the neurons are learnt with an anti-Hebbian rule. A dynamic learning rate is introduced and it is claimed that this rule improves the competition.
