Date: Wed, 15 Jun 88 11:09 EDT From: Jim Hendler <hendler@dormouse.cs.umd.edu> To: AIList-REQUEST@AI.AI.MIT.EDU Subject: Re: Connectionist expert systems There are essentially two strains of work going on in this area. One strain involves the actual implementation of expert-system-like programs using connectionist techniques. I'll let the real connectionists comment on those. The second strain involves the creation of hybrid systems which have both connectionist and symbolic mechanisms cooperating in the solution of traditional cognitivish AI problems (i.e. language, planning, ``high level'' vision, etc.) As well as my own work in this area, there is the work of Wendy Lehnert of UMass, Michael Dyer of UCLA, Mark Jones of Bell Labs, and, depending on how you classify it, the work of Dave Touretzky at CMU (Dave's work doesn't really have symbols in the traditional sense of the word, but some of his models use gating and other serial techniques to control a larger connectionist system). Also, the work of the local (now often called structured) connectionists have in some ways been hybrid. The one most related might be that of Lokendra Shastri of U Penn. -Jim Hendler U. of Md.
