Output function. Denote the weight of the connection
between node i and node j by wij, and let the
current activation of node j be aj. Then the
total net input of node j is:
netj = Σi wij ai + extinputjand then the output of node j is aj + Δaj, where:
if (netj > 0)where, max, min, decay, and rest are parameters, signifying maximum and minimum activation, decay rate in the absence of input, and the resting value to which activation will decay in the absence of input.
Δaj = (max – aj)netj – decay(aj – rest)
Δaj = (aj – min)netj – decay(aj – rest)
