Comparison to reference methods: Results for BCM, Oja and Synaptic Scaling.
Two inputs with coincidence 30% everywhere. Amplitudes and standard deviation (std) are shown above each column. Presentation frequency is equal, except in the last column where it is 2:1. Parameters: μ = 0.001. For Oja and Syn.Scaling: ω(0) = [0.001, 0.001]T, for BCM: ω(0) = [0.2, 0.2]T, ΘM(0) = 0.2, γ = 10 and v0 = 0.2; Synaptic Scaling: y0 = −200, ξ = 0.01.
