All our actions are motivated by obtaining reward, be it on the short or longer term, in one form or the other. During this process, through ...

... Multiplicative modulation at one levels means an amplification or suppression of a neuron’s output. If a neuron is tuned to respond to a preferred region, then a multiplicative modulation could cause its response to increase and decrease according to how stimuli in that region appear, but it could n ...

Memory Capacity of a Hebbian Learning Model with Inhibition
... However, these conclusions were made by assuming all stimuli are of a single coding level and by ignoring the covariances between synapses. We derive a general formula for the asymptotic synaptic covariances and extend the analysis to stimuli with two coding levels. In the old setting, it is impossi ...
