{"pk":26748,"title":"A Model of Language-Guided Concept Formation using a Common Frameworkfor Unsupervised and Supervised Learning","subtitle":null,"abstract":"A general learning rule, “BCM-δ ”, is proposed that subsumes both unsupervised learning as a form of the BCMrule (Bienenstock, Cooper, Munro, 1982; Munro, 1984) and the delta rule (Rosenblatt, 1958; Rumelhart, Hinton, and Williams,1986). The “BCM-δ ” unit is composed of two subunits, T and L, each integrating distinct input streams across distinct setsof synapses. The two subunits follow a common Hebb-like learning procedure that reduces to an unsupervised rule for the Tsubunit and a supervised rule for the L subunit in which the T response is the training signal. This model suggests a neurallyplausible mechanism for the shaping of concepts by labels. More generally, stimuli from one modality can shape the responseproperties of a unit to another modality using a framework that is biologically plausible and gives clues to the source of ateaching signal for supervised learning.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Member Abstracts","is_remote":true,"remote_url":"https://escholarship.org/uc/item/6nm577w6","frozenauthors":[{"first_name":"Paul","middle_name":"","last_name":"Munro","name_suffix":"","institution":"University of Pittsburgh","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2016-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/26748/galley/16384/download/"}]}
