{"pk":26152,"title":"The face-space duality hypothesis: a computational model","subtitle":null,"abstract":"Valentine’s face-space suggests that faces are represented in apsychological multidimensional space according to their per-ceived properties. However, the proposed framework was ini-tially designed as an account of invariant facial features only,and explanations for dynamic features representation were ne-glected. In this paper we propose, develop and evaluate a com-putational model for a twofold structure of the face-space, ableto unify both identity and expression representations in a singleimplemented model. To capture both invariant and dynamicfacial features we introduce the face-space duality hypothesisand subsequently validate it through a mathematical presen-tation using a general approach to dimensionality reduction.Two experiments with real facial images show that the pro-posed face-space: (1) supports both identity and expressionrecognition, and (2) has a twofold structure anticipated by ourformal argument.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"face perception; face processing; face-space; du-ality hypothesis; dimensionality reduction"}],"section":"Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/49t3p1zp","frozenauthors":[{"first_name":"Jonathan","middle_name":"","last_name":"Vitale","name_suffix":"","institution":"University of Technology, Sydney","department":""},{"first_name":"Mary-Anne","middle_name":"","last_name":"Williams","name_suffix":"","institution":"University of Technology, Sydney","department":""},{"first_name":"Benjamin","middle_name":"","last_name":"Johnston","name_suffix":"","institution":"University of Technology, Sydney","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/26152/galley/15788/download/"}]}
