While they are usually more focused on a<br>specific task than learning something general like dog, they often<br>require only recording a subset of information from an experience<br>for later use and/or abstracting detailed past experiences into more<br>general "categories". The assignment task in unit 5 of the ACT-R<br>tutorial requires explicitly paring down the available information from<br>a game in the model so that it can learn to play better by retrieving<br>from among those simplified past experiences. Whereas instance based<br>learning models which use the blending mechanism can dynamically<br>generalize over detailed past experiences using features determined<br>during the task to create such knowledge. I don't know of specific<br>references to models of that nature which you could get, but others<br>here can probably provide some.<br><br>Hope that helps,<br>Dan<br><br><br><br>------------------------------<br><br>Subject: Digest Footer<br><br>_______________________________________________<br>ACT-R-users mailing list<br><a href="mailto:ACT-R-users@act-r.psy.cmu.edu">ACT-R-users@act-r.psy.cmu.edu</a><br>https://mailman.srv.cs.cmu.edu/mailman/listinfo/act-r-users<br><br><br>------------------------------<br><br>End of ACT-R-users Digest, Vol 19, Issue 3<br>******************************************<br><br></blockquote></div><br><div apple-content-edited="true">
