Is there any other work done in connectionist expert systems ? Thanks.

He's read much of the literature on emulating ternary logic on binary systems, but hasn't seen much work done directly on ternary systems. Any pointers would be appreciated. Please respond directly to me at the addresses listed below, as I am not a subscriber to this newsgroup. Gerry Key Computer Sciences Corporation 4045 Hancock Street San Diego, CA 92110 U.S.A.

In the article they list some other projects in which induction over explanations is performed. Can anyone provide me with pointers to work in which induction is done over multiple concept explanations? I would particularly be interested in hearing about projects in which induction is performed over causal process explanations generated by qualitative or quantitative domain models. Please email to me (bruce@paul.rutgers.edu) any references which you might have concerning this topic. I will, of course, post the results of this query to the net if there is enough interest. Thanks for the help. -- Shane Bruce HOME: (201) 613-1285 WORK: (201) 932-4714 ARPA: bruce@paul.rutgers.edu UUCP: {ames, cbosgd, harvard, moss}!rutgers!paul.rutgers.edu!bruce ------------------------------ Date: Fri, 10 Jun 88 16:34:59 CDT From: halcdc!tciaccio Reply-to: shamash!jwabik@umn-cs.arpa (Jeff Wabik) Subject: Graphics on PC using GCL LISP? We are trying to do windows (both text and graphics) and mouse events from GCL LISP and MS-DOS. Would also like to display digitized pictures in these windows. Is anyone doing such a thing out there? Should we start with GC-WINDOWS or the Gold Hill Extended Programming Interface (EPI) to something like C ? Any info would be much appreciated.

The findings indicate that elementary school children's early beliefs are consistent with their phenomenal explanation of a stationary flat earth and an up and down movement of the sun and moon. These beliefs appear to be quite resistant to change and rise to a number of misconceptions which reveal children's difficulty to assimilate current scientific views. ------------------------------ End of AIList Digest ********************
