Abstract

The developmental neural network is trained using a synaptic maintenance process. Synaptogenic trimming is first performed on the neuron inputs using a synaptogenic factor for each neuron based on standard deviation of a measured match between the input and synaptic weight value. A top-k competition among all neurons then selects a subset of said neurons as winning neurons. Neuronal learning is applied only to these winning neurons, updating their synaptic weights and updating their synaptogenic factors.
