Anunsupervisedcompetitivelearningrule is introducedfor topology-preserving mapformation.The rule, calledvectorialboundaryadaptationrule (VBAR),achievesa “maximally’ ’-orderedmapby peglorrninglocalweight updatesonly:hence,contrarytoKohonen’sself-organizingmap(SOM)algorithm,no neighborhood finction isneeded. Weformalize VBAR’Slearningdynamicsandshowby simulationsthat it convergesin a completelydifferentwayfiom the SOM algorithm.Our rule is aimedat achievingan equiprobablequantizationof the input… CONTINUE READING
