ICA with spiking neurons

Abstract:

We propose a biologically plausible mechanism for performing ICA with spiking neurons. We show that a stochastically spiking neuron is able to learn one inde- pendent component in the input, by combining spike-timing dependent plasticity (STDP) with an intrinsic plasticity rule, which regulates the neuron response prop- erties to maximize information transmission, under the constraint of a fixed mean firing rate. A population of such neurons is shown to perform ICA when their activities are decorrelated by adaptive lateral inhibition.
