AIList Digest Sunday, 15 Dec 1985 Volume 3 : Issue 186 Today's Topics: Seminars - Learning Objects from Images (MIT) & SDI Debate (SU) & Deduction as a Programming Methodology (UTexas) & Typed Equational Logic Programming (UTexas), Conference - Expert Systems in Government & Object-Oriented Programming System, Languages, and Applications ---------------------------------------------------------------------- Date: Tue, 10 Dec 85 20:06 EST From: Brian C. Williams <WILLIAMS at OZ.MIT.EDU> Subject: Seminar - Learning Objects from Images (MIT) [Forwarded from the MIT bboard by SASW@MIT-MC.] Thursday , December 12 4:00pm Room: NE43- 8th floor Playroom The Artificial Intelligence Lab Revolving Seminar Series "Learning Symbolic Object Models From Images" Jonathan Connell MIT, AI Lab This talk will present the results of an implemented system for learning structural prototypes of objects directly from gray-scale images. The vision component of this system employs Brady's Smoothed Local Symmetries to divide an object into parts which are then described symbolically. The learning component takes these descriptions and forms a model of the examples presented in a manner similar to Winston's ANALOGY program. The problem of matching complex structured descriptions and the difficult task of reasoning about function from form will also be briefly discussed. ------------------------------ Date: Fri 13 Dec 85 17:56:01-PST From: Joan Feigenbaum <JF@SU-SUSHI.ARPA> Subject: Seminar - SDI Debate (SU) ``SDI: How Feasible, How Useful, How Robust?''

A higher-order intuitionistic natural deduction formalism, the Calculus of Constructions, is introduced and motivated by examples. ------------------------------ Date: Fri 13 Dec 85 11:55:40-CST From: <AI.HASSAN@MCC.ARPA> Subject: Seminar - Typed Equational Logic Programming (UTexas) Typed Equational Logic as a Programming Language Gert Smolka Cornell University MCC-AI Lecture WEDNESDAY, DECEMBER 18 at 3:00pm Echelon I, Room 409 I will present a logic programming notation called TEL, which is based on typed equational logic. TEL avoids many of Prolog's difficulties since it has equality and functions, an expressive type system, and more satisfying control features. Furthermore, employing equational rather than relational logic supports term rewriting in addition to logic programming a la Prolog. TEL's major innovations come with its type system: * Both type containment (subtypes as in OBJ2) and parametric polymorphism (as in ML) are available. This requires type checking algorithms that solve inequalities. * Although, in general, types are computationally significant, every program can be automatically translated into an equivalent TEL program in which all type information is redundant. Thus TEL can be implemented with untyped narrowing. * Type declarations in TEL contain control information that enables a compiler to decide whether a function can be implemented by rewriting instead of full narrowing. This is a crucial optimization since rewriting requires neither backtracking nor unification. * The control information in TEL's type declarations also facilitates the exploitation of and-parallism. A straight- forward compile-time analysis can determine most subterms that will not share variables at run-time. ------------------------------ Date: 13 Dec 85 10:30:25 EST (Fri) From: Duke Briscoe <duke@mitre.ARPA> Subject: Conference - Expert Systems in Government CALL FOR PAPERS THE SECOND ANNUAL CONFERENCE ON EXPERT SYSTEMS IN GOVERNMENT Tyson's Westpark Hotel, McLean, VA in suburban Washington, D.C.

Through tutorials, papers, panel discussions and workshops, as well as demonstrations, exhibits and videotapes, OOPSLA-86 will provide a forum for sharing experience and knowledge among experts and novices alike. We invite technical papers, case studies, and surveys in the following areas: Theory: Including core definition of object oriented programming, semantic models and methodology. Languages: Existing object oriented languages, extensions to conventional languages, and new languages. Implementation: Including architectural support, compilation and interpretation, and special techniques. Tools and Environments: Including user interfaces, utilities and operating system support. Applications: Commercial, educational, and scientific applications that exploit object oriented programming. Related Work: The object oriented paradigm in other fields such as databases and operating systems. Papers on other relevant topics are welcome, as are proposals for workshops and panel discussions. All papers will be refereed prior to selection and inclusion in the conference proceedings. Technical papers will be selected on the basis of originality and contribution to the state of the art of design, implementation, methodology, or practice. Survey papers will be selected on the basis of how well they crystallize and integrate, in a way not previously presented, knowledge about one or more aspects of the field. Papers must be submitted in English, and should be no longer than 25 double-spaced pages. The cover page should include a title, an abstract of not more than 100 words, and author's name, affiliation, address and phone number. Five copies must be received by the Program Chairman at the address below, no later than April 1, 1986. Authors will be notified of acceptance by May 1, 1986, and final versions of accepted papers will be due by June 15, 1986. As the proceedings of this conference will be widely disseminated, publication of more than an abstract of a submitted paper is likely to inhibit republication in ACM's refereed publications. A room at the conference will be reserved for video presentations that illustrate or supplement the concepts conveyed in other presentations. Submissions must run no longer than 15 minutes, and should be on 3/4-inch U-Matic format tape. Tapes must be received by the Video Chairman at the address below, no later than July 1, 1986.
