{"pk":29536,"title":"Beyond Pattern Completion with Short-Term Plasticity","subtitle":null,"abstract":"In a Linear Associative Net (LAN), all input settles to a singlepattern, therefore Anderson, Silverstein, Ritz, and Jones (1977)introduced saturation to force the system to reach othersteady-states in the Brain-State-in-a-Box (BSB). Unfortunately,the BSB is limited in its ability to generalize because itsresponses are restricted to previously stored patterns. We presentsimulations showing how a Dynamic-Eigen-Net (DEN), a LANwith Short-Term Plasticity (STP), overcomes thesingle-response limitation. Critically, a DEN also accommodatesnovel patterns by aligning them with encoded structure. We traina two-slot DEN on a text corpus, and provide an account oflexical decision and judgement-of-grammaticality (JOG) tasksshowing how grammatical bi-grams yield stronger responsesrelative to ungrammatical bi-grams. Finally, we present asimulation showing how a DEN is sensitive to syntacticviolations introduced in novel bi-grams. We propose DENs asassociative nets with greater promise for generalization than theclassic alternatives.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Content Addressable Memory; Auto-associative;Recurrent; Short-Term Plasticity; Generalization"}],"section":"Poster Session 1","is_remote":true,"remote_url":"https://escholarship.org/uc/item/5279t2c3","frozenauthors":[{"first_name":"Kevin","middle_name":"D.","last_name":"Shabahang","name_suffix":"","institution":"The University of Melbourne","department":""},{"first_name":"Hyungwook","middle_name":"","last_name":"Yim","name_suffix":"","institution":"The University of Melbourne","department":""},{"first_name":"Simon","middle_name":"J.","last_name":"Dennis","name_suffix":"","institution":"The University of Melbourne","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2020-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/29536/galley/19396/download/"}]}
