{"pk":29201,"title":"High-Dimensional Vector Spaces as the Architecture of Cognition","subtitle":null,"abstract":"We demonstrate that the key components of cognitive architectures - declarative and procedural memory - and their keycapabilities - learning, memory retrieval, judgement, and decision-making - can be implemented as algebraic operationson vectors in a high-dimensional space. Modern machine learning techniques have an impressive ability to process datato find patterns, but typically do not model high-level cognition. Traditional, symbolic cognitive architectures can capturethe complexities of high-level cognition, but have limited ability to detect patterns or learn. Vector-symbolic architec-tures, where symbols are represented as vectors, bridge the gap between these two approaches. Our vector-space modelaccounts for primacy and recency effects in free recall, the fan effect in recognition, human probability judgements, andhuman performance on an iterated decision task. Our model provides a flexible, scalable alternative to symbolic cognitivearchitectures at a level of description that bridges symbolic, quantum, and neural models of cognition.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Member Abstracts","is_remote":true,"remote_url":"https://escholarship.org/uc/item/88v0k9pt","frozenauthors":[{"first_name":"Matthew","middle_name":"","last_name":"Kelly","name_suffix":"","institution":"The Pennsylvania State University","department":""},{"first_name":"Nipun","middle_name":"","last_name":"Arora","name_suffix":"","institution":"Carleton University","department":""},{"first_name":"Robert","middle_name":"","last_name":"West","name_suffix":"","institution":"Carleton University","department":""},{"first_name":"David","middle_name":"","last_name":"Reitter","name_suffix":"","institution":"Penn State","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2019-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/29201/galley/19072/download/"}]}
