{"pk":29814,"title":"Deep daxes: Mutual exclusivity arises through both learning biases and pragmaticstrategies in neural networks","subtitle":null,"abstract":"Children’s tendency to associate novel words with novel refer-ents has been taken to reflect a bias toward mutual exclusivity.This tendency may be advantageous both as (1) an ad-hoc ref-erent selection heuristic to single out referents lacking a labeland as (2) an organizing principle of lexical acquisition. Thispaper investigates under which circumstances cross-situationalneural models can come to exhibit analogous behavior to chil-dren, focusing on these two possibilities and their interaction.To this end, we evaluate neural networks’ on both symbolicdata and, as a first, on large-scale image data. We find thatconstraints in both learning and selection can foster mutual ex-clusivity, as long as they put words in competition for lexi-cal meaning. For computational models, these findings clarifythe role of available options for better performance in taskswhere mutual exclusivity is advantageous. For cognitive re-search, they highlight latent interactions between word learn-ing, referent selection mechanisms, and the structure of stimuliof varying complexity: symbolic and visual.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"neural networks; mutual exclusivity; acquisition;pragmatics; learning biases; lexical meaning; referent selec-tion"}],"section":"Poster Session 2","is_remote":true,"remote_url":"https://escholarship.org/uc/item/17v3f7p8","frozenauthors":[{"first_name":"Kristina","middle_name":"","last_name":"Gulordava","name_suffix":"","institution":"Universitat Pompeu Fabra","department":""},{"first_name":"Thomas","middle_name":"","last_name":"Brochhagen","name_suffix":"","institution":"Universitat Pompeu Fabra","department":""},{"first_name":"Gemma","middle_name":"","last_name":"Boleda","name_suffix":"","institution":"Universitat Pompeu Fabra","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/29814/galley/19668/download/"}]}
