{"pk":30624,"title":"Acquiring Special Case Schemata In Explanation-Based Learning","subtitle":null,"abstract":"Much of expertise in problem-solving situations involves rajiidly choosinj? a tightly-constrained schema that is appropriate to the current problem. The paradigm of explanation-based learning, is being applied to investigate hou- an intelligent system can acquire these \"appropriately general\" schemata. While the motivations for producing these specialized schemata are computational, results reported in the psychological literature are corroborated by a fully-implemented comjjuter model. .Acquiring these special case schemata involves combining schemata from two different classes. One class contains domain-independent problem solving schemata, while the other class consists of domain-specific knowledge. By analyzing solutions to sample problems, new domain knowledge is produced that often is not easily usable by the problem-solving schemata. .Special case schemata result from constraining these general schemata so that a k n o w n problem solving technique is guaranteed to work. This significantly reduces the amount of ])lanning that the problemsolver would other>*ise need to perlorm elaborating the general schema in a n e w problem-solving situation.The model and an application of it in the domain of classical physics are presented.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Artificial Intelligence and Simulation II","is_remote":true,"remote_url":"https://escholarship.org/uc/item/15s810dd","frozenauthors":[{"first_name":"Jude","middle_name":"W.","last_name":"Shavlik","name_suffix":"","institution":"Coordinated Science Laboratory","department":""},{"first_name":"Gerald","middle_name":"F.","last_name":"DeJong","name_suffix":"","institution":"Coordinated Science Laboratory","department":""},{"first_name":"Brain","middle_name":"H.","last_name":"Ross","name_suffix":"","institution":"University of Illinois at Urbana-Champaign","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"1987-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/30624/galley/20473/download/"}]}
