{"pk":27800,"title":"A Neueal Network Model of Complementary Learning Systems","subtitle":null,"abstract":"We introduce a computational model capturing the high-level\nfeatures of the complementary learning systems (CLS) frame-\nwork. In particular, we model the integration of episodic mem-\nory with statistical learning in an end-to-end trainable neural\nnetwork architecture. We model episodic memory with a non-\nparametric module which can retrieve past observations in re-\nsponse to a given observation, and statistical learning with a\nparametric module which performs inference on the given ob-\nservation. We demonstrate on vision and control tasks that our\nmodel is able to leverage the respective advantages of nonpara-\nmetric and parametric learning strategies, and that its behavior\naligns with a variety of behavioral and neural data. In partic-\nular, our model performs consistently with results indicating\nthat episodic memory systems in the hippocampus aid early\nlearning and transfer generalization. We also find qualitative\nresults consistent with findings that neural traces of memories\nof similar events converge over time. Furthermore, without\nexplicit instruction or incentive, the behavior of our model nat-\nurally aligns with results suggesting that the usage of episodic\nsystems wanes over the course of learning. These results sug-\ngest that key features of the CLS framework emerge in a task-\noptimized model containing statistical and episodic learning\ncomponents, supporting several hypotheses of the framework.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Publication-based-Talks","is_remote":true,"remote_url":"https://escholarship.org/uc/item/5845p3bv","frozenauthors":[{"first_name":"Mika","middle_name":"Sarkin","last_name":"Jain","name_suffix":"","institution":"Stanford","department":""},{"first_name":"Jack","middle_name":"","last_name":"Lindsey","name_suffix":"","institution":"Stanford","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/27800/galley/17440/download/"}]}
