Abstract: An unsupervised competitive learning rule, called the vectorial boundary adaptation rule (VBAR), is introduced for topographic map formation, Since VBAR is aimed at producing an equiprobable quantization of the input space, it yields a nonparametric model of the input probability density function, Furthermore, since equiprobable quantization is equivalent to unconditional entropy maximization, we will argue that this is a plausible strategy for maximizing mutual information (Shannon information rate) in the case of ''on-line'' learning, We will use mutual information as a tool for comparing the performance of our rule with Kohonen's self-organizing (feature) map algorithm.
