Abstract
PURPOSE:To improve the performance of input pattern discrimination by varying a weighting function by a studying function according to a weighted input signal. CONSTITUTION:For input signals X1(t)-XK(t), a weighting function W(t,t') is used to obtain u(t,t')= 0<t>W(t-tau,t').X(tau,t')dtau. Then, it make study with W(t,t'+1)= a.W(t,t')+C.X(t,t').y(t,t') by an output (z) of a 1 when the (u) is greater than the threshold level (h) or of a 0 when less. The (y) is solved as a linear programming problem. The weight function W is recognized more stably by advancing the studying each time each input is updated.
