Unimodal or Bimodal Distribution of Synaptic Weights?
... Most Hebbian learning rules or BCM rules used to describe receptive field development exhibit a spontaneous separation of synaptic weights into two groups, i.e., strong and weak synapses, so that the distribution of synaptic weights is bimodal. This implies that even rather ‘weak’, non-significant c ...
