Preferably, I like one in the public domain. D. E.

This was stimulated by the new Tektronix AI machine, whose blurb touts its SmallTalk as useful for developing expert systems. Take a look at the Troubleshooter for the Tektronix 4404. Although I am not on the "inside" on this one, It is a rule based system written in Smalltalk. One of the program's principles (Jim Alexander) is a Cognitive Scientist and not, strictly speaking, a propgrammer, which attests to the ease with which such things can be done in Smalltalk. The Troubleshooter has two graphic and several text windows. The graphic windows present a schematic and a parts layout, each having little probes that move from point to point. A text window asks questions, such as "Is the voltage at N19 high?"; the answers of such questions cause the probe(s) to move to the next test point. Other text windows can be opened on a parts database, troubleshooting advice, and the actual rules program, among others. (Remember, the full power of Smalltalk is always available, which is good and bad!) A window can be opened on a scope screen, which shows expected waveforms at various points. I have seen it; it works; it's fun! I fixed stereos, transceivers, and color TVs before getting into computers and know that half the battle in troubleshooting is often using the service literature! This application is sort of a smart, graphics-based, hypertext service manual and would really be useful. It is not simply an interesting bit of AI research! I AM NOT A PART OF THIS PROJECT. Although I don't want to seem anti-social, please contact your nearest Tek field office for a demo and more information; do not contact me! :::::: Jan Steinman Box 1000, MS 61-161 (w)503/685-2843 :::::: :::::: tektronix!tekecs!jans Wilsonville, OR 97070 (h)503/657-7703 :::::: ------------------------------ Date: 2 Jan 1985 09:58:48-EST From: kushnier@NADC Subject: VILM Todd, We at NAVAIRDEVCEN are also interested in a Low cost portable LISP machine. The MAC came up as a possible candidate. Could you please tell me more about Portable Standard LISP (PSL) ? We are currently considering implementing an EXPERT SYSTEM written in FORTH which we would translate into MACFORTH. Unless an external high speed, high capacity memory device can be utilized, the prospect of using LISP does not look promising. Keep us informed on your progress.

Does the reference to the proof of Fermat's Last Theorem (Vol 2 # 181) have anything to do with the incorrect proof of Arnold Arnold which was reported in the Guardian newspaper in October/November 1984 ?

I would hate to be the one doing the compiling, though. ------------------------------ Date: Thu, 3 Jan 85 13:01:25 est From: chester%vax1@cc.delaware (CHESTER) Subject: Re: Cognitive Science Dictionary A dictionary (with short definitions of terms) would have limited sales, since it would only be useful to people who are already in the field or who already have strong motivation to get in the field and are required to buy it for a course. An encyclopedia would be better, but I favor a format like that of The Handbook of Artificial Intelligence, (Barr and Feigenbaum) or the Handbook of Human Intelligence (Sternberg). Such a work would appeal to people who have a moderate interest in the field and might give them suitable orientation and motivation to join us. ------------------------------ Date: Friday, 21 Dec 1984 18:12-PST From: imagen!les@su-shasta.arpa Subject: TV and the 5th generation [Forwarded from the Human-Nets Digest by Laws@SRI-AI.] In response to your 20 Dec. comments on "Personal Assistants", I can confirm that the TV story is apocryphal. I bought the Heathkit television set for the Stanford AI Lab and it was completely assembled within a few days after arrival, by gnomes not robots. Aside from its use for monitoring "Mary Hartman! Mary Hartman!" it served as a display for computer-synthesized color images. A creative student (Hans Morovec) shortly built a remote control ray gun that worked rather well. As I recall, that was a few years before remote control became available on commercial TV sets. As for the digs at the AI community by you and others, please do not paint everyone with the same brush. In any research field, the lunatic fringe is much more likely to catch headlines and certain government grants than those who speak rationally. The Great Machine Translation fiasco of the '60s was brought about mainly by the CIA's slavering desire to leap ahead in an area where no one knew how to walk yet. An even greater fiasco was the series of "Command and Control" systems assembled by the Air Force and others in the '50s, '60s, and '70s. They wanted computers to run the military establishment even though they hadn't mastered chess yet. The reason that these largely useless projects kept going was that the people involved were having a good time (and making good money) and the Congress never seemed to understand what was going on. As for AI and 5th generation computers, I know of very few people in the AI community who believe in any of that nonsense. Nevertheless, some will use it to pry larger grants out of the government or to sell high-priced seminars to the gullible public. What keeps happening, it seems, is that people take a few partially- understood facts and principles then extrapolate a few light years away and declare that it must be possible to do this new thing. As long as such activities are rewarded, they will continue to proliferate. Why settle for a trip to the beach when you can head toward Andromeda? Les Earnest ------------------------------ Date: 02 Jan 85 2300 PST From: Richard Vistnes <RV@SU-AI.ARPA> Subject: Reading machines & news I seem to remember someone a while ago asking about the availability of machines that could `read' a page of text with a camera and produce computer-readable text. In the latest issue of Fortune magazine (Jan 7 '85, p.74) there's an article about speech recognition, and it mentions that Kurzweil (formerly of MIT, I believe) let Xerox produce his reading machine, and that this machine can read text in several different fonts. Maybe someone at Xerox can supply more information. - Richard Vistnes ------------------------------ Date: 02 Jan 85 1107 PST From: Yoni Malachi <YM@SU-AI.ARPA> Subject: Upcoming conference submission deadlines [Forwarded from the Stanford bboard by Laws@SRI-AI.] (details in file CONFER.TXT[2,2] at SAIL.) 7-Jan-85: IJCAI-85 10-Jan-85: VLSI-85 12-Jan-85: Theoretical Approaches to Natural Language Understanding 14-Jan-85: Logics of Programs 1985 15-Jan-85: Symposium on Complexity of Approximately Solved Problems 15-Jan-85: Workshop on Environments for Programming-in-the-Large 15-Jan-85: 1985 CHAPEL HILL CONFERENCE ON VLSI 18-Jan-85: Computational Linguistics 31-Jan-85: FUNCTIONAL PROGRAMMING LANGUAGES AND COMPUTER ARCHITECTURE 31-Jan-85: Conference - Intelligent Systems and Machines 4-Feb-85: CONFERENCE ON SOFTWARE MAINTENANCE -- 1985 4-Feb-85: Sigmetrics '85 11-Mar-85: THEORETICAL AND METHODOLOGICAL ISSUES IN MACHINE TRANSLATION OF NATURAL LANGUAGES 1-Apr-85: Logic, language and computation meeting 29-Apr-85: FOUNDATIONS OF COMPUTER SCIENCE (FOCS) 1-May-85: Expert Systems in Government Conference You can get the file to your computer using FTP. ------------------------------ Date: Wed 2 Jan 85 17:16:47-PST From: Emma Pease <Emma@SU-CSLI.ARPA> Subject: Seminar - Representation and Presentation (CSLI) [Excerpted from the CSLI Newsletter by Laws@SRI-AI.] CSLI SEMINAR ``Representation and Presentation'' Benny Shanon, Hebrew University of Jerusalem Wednesday, January 9 at 4:00 pm in the Ventura conference room A series of arguments, drawn on the basis of various aspects of psychological phenomenology are marshalled against the representational- computational view of mind. The argument from context marks the unconstrained variation of meaning with context, hence the impossibility of a full, comprehensive semantic representation; the argument from medium points out that medium is an ineliminable contributor to meaning and that a variety of psychological patterns do not allow for a distinction between medium and message, hence they cannot be accounted for by means of abstract, symbolic representations; the argument from development notes that the representational view not only cannot account for the problem of the origin in cognition, but that it leads to unnatural and even paradoxical patterns whereby what is theoretically simple is phenomenologically complex and/or developmentally late and what is theoretically complex is phenomenologically simple and/or developmentally early. On the basis of these arguments it is suggested that cognition be viewed as a dialectic process between two types of patterns: representational and presentational. ------------------------------ Date: 02 Jan 85 2347 PST From: Yoni Malachi <YM@SU-AI.ARPA> Subject: Seminar - Rewrite Rules for Functional Programming (IBM-SJ) [Forwarded from the Stanford bboard by Laws@SRI-AI.] 2:00pm Monday, Jan. 7 Room 1C-012 (in Building 28 at IBM) Ed Wimmers IBM Research San Jose What does it mean for rewrite rules to be "correct"? We consider an operational definition for FP via rewrite rules. What would it mean for such a definition to be correct? We certainly want the rewrite rules to capture correctly our intuitions regarding the meaning of the primitive functions. We also want there to be enough rewrite rules to compute the correct meaning of all expressions, but not too many, thus making equivalent two expressions that should be different. And what does it mean for there to be "enough" rules? We develop a new formal criterion for deciding whether there are enough rewrite rules and show that our rewrite rules meet that criterion. Our proof technique is novel in the way we use the semantic domain to guide an assignment of types to the untyped language FP; this allows us to adopt powerful techniques from the typed lambda-calculus theory.
