{"pk":27858,"title":"Capturing human category representations by sampling in deep feature spaces","subtitle":null,"abstract":"Understanding how people represent categories is a core prob-lem in cognitive science. Decades of research have yieldeda variety of formal theories of categories, but validating themwith naturalistic stimuli is difficult. The challenge is that hu-man category representations cannot be directly observed andrunning informative experiments with naturalistic stimuli suchas images requires a workable representation of these stimuli.Deep neural networks have recently been successful in solvinga range of computer vision tasks and provide a way to com-pactly represent image features. Here, we introduce a methodto estimate the structure of human categories that combinesideas from cognitive science and machine learning, blendinghuman-based algorithms with state-of-the-art deep image gen-erators. We provide qualitative and quantitative results as aproof-of-concept for the method’s feasibility. Samples drawnfrom human distributions rival those from state-of-the-art gen-erative models in quality and outperform alternative methodsfor estimating the structure of human categories.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Categorization"},{"word":"Neural Networks"},{"word":"Markov chain Monte Carlo"}],"section":"Publication-based-Talks","is_remote":true,"remote_url":"https://escholarship.org/uc/item/7b4322c3","frozenauthors":[{"first_name":"Joshua","middle_name":"C","last_name":"Peterson","name_suffix":"","institution":"UC Berkley","department":""},{"first_name":"Jordan","middle_name":"W","last_name":"Suchow","name_suffix":"","institution":"UC Berkley","department":""},{"first_name":"Krisha","middle_name":"","last_name":"Aghi","name_suffix":"","institution":"UC Berkley","department":""},{"first_name":"Thomas","middle_name":"L","last_name":"Griffiths","name_suffix":"","institution":"UC Berkley","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2018-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/27858/galley/17496/download/"}]}
