The company went out of business two years ago, and no longer supports the software. If you are looking to sell your copy of EXPERT-EASE, or know someone who is please let me know. My copy crashed and I need the software to complete my research. Please respond to 6200265@PUCC on BITNET, or call (609) 452-5340 during the day. ********************** Thank You ******************** Brenda Belkin. ------------------------------ Date: Sun, 04 Sep 88 16:21 EST From: steven horst Subject: references on language simulation I have an undergraduate student who is interested in researching AI work in language simulation. I am familiar with the main PROFESSIONAL publications, but don't know of anything that would give a beginning student a good and reasonably up-to-date description of major research areas and point him in the right direction for whatever specific topics he may wish to pursue further. He has expressed a mild interest in parsers and a stronger interest in work that involves knowledge representation and context sensitivity. I should appreciate suggestions for: (a) Survey texts (b) Literature review articles (c) Bibliographies (especially annotated ones). Please send any suggestions to my bitnet address: Steven Horst gkmarh@irishmvs.bitnet Department of Philosophy Notre Dame, IN 46556 ------------------------------ Date: MON 5 SEP 88 From: Levent Akin Subject: Linguistic multivariable controller for a nuclear power plant I am a doctoral student (in nuclear engineering) and I plan to build a linguistic multivariable controller for a nuclear power plant(represented by a set of first order linear differential equations. I think there are two possible ways of building the meta-level knowledge base: 1) A reflection of the plant model(actually a subset considering the observable variables) such as: "If fuel temperature increases then time rate of power change decreases." or 2) Start with a minimum set of rules and build the knowledge base using repeated simulation and a scoring mechanism. Since in Turkey I have very limited access to AI literature such as proceedings and reports, any suggestions, flames, etc. to put me on the right track are welcome. ******************************************************************************* *The recipe for perpetual ignorance is: be satisfied with your opinions and * *content with your knowledge. * * Elbert Hubbard, The Philistine Vol. V * ******************************************************************************* ------------------------------------------------------------------------------- Levent Akin e-mail:EARN(BITNET): Bogazici Universitesi Muhendislik Fakultesi P.K.2 80815 Bebek-Istanbul TURKEY ------------------------------ Date: 5-SEP-1988 09:58:48 From: <75008378%VAX2.NIHED.IE@MITVMA.MIT.EDU> Subject: Darwinism applied to Machine Learning. Hello, I'm a lecturer in the School of Electronic Engineering here in NIHED in Dublin, and I'll shortly be embarking on research for a PhD. I am interested in Machine Learning, particularly with a minimal knowledge base and/or using "darwinian"/genetic type mechanisms. I'd appreciate hearing from people working in this area (especially, but not exclusively, in Ireland or the UK). As a quid pro quo, I have just completed an internal research report, reviewing some work on adaptive classifier systems (Holland et al) and neuronal group selection (Reeke & Edelman); I won't post it because its rather long, but I'll happily e-mail it to anyone who's interested.

Hello, We have the following problem: We have about 200 items. Each item belongs to one of 13 classes and is described by 12 attributes. The values an item has for these 12 attributes are not absolute, however, but are expressed relative to the other items. Like this: attr1 attr2 attr3 attr4 3 2 4 3 2 3 3 4 1 4 2 2 4 1 1 1 The numbers refer to items 1 to 4. Let's say that item 1 belongs to class 1, item 2 to class 3, item 3 to class 6 and item 4 to class 3. There is a correlation between the class an item belongs to and the positions it has for each attribute. We can see, for instance, that item 3 is ranked above item 1 for all attributes and that the class of item 3 is higher than the class of item 1. If we look at items 2 and 4, we see that of these two for some attributes item 2 is ranked higher and for some attributes item 4. Both items belong to the same class. What we want to do now, is to check the consistency of the correlation between the class an item belongs to and the relative positions it occupies for the twelve attributes. For instance, an item that is ranked very high for each attribute should not belong to the same class as an item that is ranked very low for each attribute. We want to start with e.g. 50 items and check for each new item that we add whether its class and positions are consistent with the other items. Our questions are: Can we use an inductive tool for this problem? Are 50 cases, with 12 attributes each, enough to start working with? Can we find inconsistencies, which might be rather vague, with such a tool? Is it possible to incorporate fuzzy logic in an inductive tool? Which tool should we use? Any comments are highly appreciated.
