{"pk":31766,"title":"The Acquisition of a Procedure Schema from Text and Experiences","subtitle":null,"abstract":"Learning from problem solving episodes has\npreviously been modeled in two different ways: Case-\nbased planners ( H a m m o n d , 1989) acquire additional\nknowledge by storing n e w cases (i.e. the specific\nplans for different problems); search-based systems\nlike S O A R or P R O D I G Y learn by chunking the\nresult of a search process (Rosenbloom eL al., 1991;\nMinton et. al., 1989) and by forming macro-\noperators (Korf, 1985). This paper proposes\ncomprehension-based learning as a third possibility:\nFrom specific problem solving experiences (cases)\nand a related problem description (text) some coarse-\ngrained abstract representation is constructed, that\nm a y initially be inconsistent and redundant. B y\nwholistic integration processes a coherent and\nconsistent procedure schema is subsequently formed.\nSuch a procedure schema can be reused for obtaining\nsolutions to jH-oblems which are quite different at the\nconcrete level, but have been comprehended to share\nabstract commonalties. T h e acquisition of such a\nprocedure schema is exemplified for various solutions\nto different Tower of Hanoi problems (3-, 4-, and 5-\ndisks). T h e utilization of these schemata is then\ndiscussed for the 4-disk problem and respective\nexperimental data are reported.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Submitted Presentations","is_remote":true,"remote_url":"https://escholarship.org/uc/item/1w33d36t","frozenauthors":[{"first_name":"Franz","middle_name":"","last_name":"Schmalhofer","name_suffix":"","institution":"German Research Center for Artificial Intelligence","department":""},{"first_name":"Bidjan","middle_name":"","last_name":"Tschaitschian","name_suffix":"","institution":"German Research Center for Artificial Intelligence","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"1993-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/31766/galley/22834/download/"}]}
