Architecture and open loop simulations of ISO3-Learning. Different from ISO Learning, a contains a third factor R (relevance signal), which controls the moment of the weight change. b Shows the signal structure and gives a graphical indication of the strengths of the auto-(AC) and cross-correlation (CC) contributions. c compares the weight development of ISO with ISO3 for the signal structure and filter characteristics shown in b. ISO3 does not produce any upwards drift anymore when switching x 0 off. d Shows the weight change curve. The parameters of the band-bass used for R were a = 0.6, b = 0.66, σ = 0.06 and T R = T in all cases
