First, we show that no second-order noniterative local learning rule allows an efficient storage of words (but interneural couplings of an order at least equal to the number of letters in a word are neccessary). Besides, for the case of three-letter words, we show that any second-order coupling leads to frustration when two letters are presented. Then, we derive some properties of a neural network model based on a generalized high-order Hebb\u2019s rule and coupled subnets, and we show that it solves efficiently the problem of storage and retrieval of words.<\/p>\n","protected":false},"featured_media":925,"template":"","class_list":["post-683","publicacion","type-publicacion","status-publish","has-post-thumbnail","hentry","lineas-redes-neuronales-artificiales","revista-physical-review-e"],"acf":[],"_links":{"self":[{"href":"https:\/\/cib.udp.cl\/en\/wp-json\/wp\/v2\/publicacion\/683","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/cib.udp.cl\/en\/wp-json\/wp\/v2\/publicacion"}],"about":[{"href":"https:\/\/cib.udp.cl\/en\/wp-json\/wp\/v2\/types\/publicacion"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/cib.udp.cl\/en\/wp-json\/wp\/v2\/media\/925"}],"wp:attachment":[{"href":"https:\/\/cib.udp.cl\/en\/wp-json\/wp\/v2\/media?parent=683"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
