A recurrent neural network with ever changing synapses
M Heerema, W A van Leeuwen · Journal of Physics A Mathematical and General · 2000
A recurrent neural network with noisy input is studied analytically, on the basis of a discrete time master equation. The latter is derived from a biologically realizable learning rule for the weights of the connections. In a numerical study it is found that the fixed points of the dynamics of the net are time dependent, implying that the representation in the brain of a fixed piece of information (e.g., a word to be recognized) is not fixed in time.
