{"pk":25966,"title":"Cognitive Modeling of Life Story: Reconstructing Our Memories from a Photo\nLibrary","subtitle":null,"abstract":"Assuming that photographs accumulated in a personal computer reflect life history of a user, a model of one’s\nautobiographical memory could be constructed. Such a model will be useful to support memory problems caused by such as\naging. Based on this idea, we constructed an image recommender system including an ACT-R model. We build the model\nusing the first author’s private photo library, consisting 3,202 photos. We run a simulation manipulating the activation noise of\ndeclarative chunks. As a result, we found strong influence of the noise on memory retrieval. When the noise level was low,\nthe model retrieved a few memory items that occurred recently. On the other hand, when the noise level was high, the retrieval\nprocess was like random walk over a memory network. Repeated recalls of old photos occurred. The result suggests a condition\nof an ACT-R model enabling a travel into a distant past.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Member Abstracts","is_remote":true,"remote_url":"https://escholarship.org/uc/item/21p992tq","frozenauthors":[{"first_name":"Junya","middle_name":"","last_name":"Morita","name_suffix":"","institution":"Nagoya University","department":""},{"first_name":"Takatsugu","middle_name":"","last_name":"Hirayama","name_suffix":"","institution":"Nagoya University","department":""},{"first_name":"Kenji","middle_name":"","last_name":"Mase","name_suffix":"","institution":"Nagoya University","department":""},{"first_name":"Kazunori","middle_name":"","last_name":"Yamada","name_suffix":"","institution":"Panasonic Corporation","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2015-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/25966/galley/15590/download/"}]}
