Heuristic Techniques in Computer Aided Circuit Analysis
(1975-03-01)
We present EL, a new kind of circuit analysis program. Whereas other circuit analysis systems rely on classical, formal analysis techniques, EL employs heuristic "inspection" methods to solve rather complex DC bias ...
Spatial Disposition of Axes in a Generalized Cylinder Representation of Objects
(1975-12-01)
It is proposed that the 3-D representation of an object is based primarily on a stick-figure configuration, where each stick represents one or more axes in the object's generalized cylinder representation. The loosely ...
Very Large Planner-Type Data Bases
(1975-09-01)
This paper describes the implementation of a typical data-base manaer for an A.I. language like Planner, Conniver, or QA4, and some proposed extensions for applications involving greater quantities of data than usual. ...
Early Processing of Visual Information
(1975-12-01)
The article describes a symbolic approach to visual information processing, and sets out four principles that appear to govern the design of complex symbolic information processing systems. A computational theory of ...
Leading a Child to a Computer Culture
(1975-12-01)
"LOGO" is sometimes used as the name of a programming language. It is also used as the name of...what shall I call it?... an environment, a culture, a way of thinking about computers and about learning and about putting ...
The Development of Musical Intelligence I: Strategies for Representing Simple Rhythms
(1975-11-01)
This paper is the first in a series of monographs which will describe various aspects of the development of musical intelligence.
LLOGO: An Implementation of LOGO in LISP
(1975-03-01)
This paper describes LLOGO, an implementation of the LOGO language written in MACLISP for the ITS, TEN50 and TENEX PDP-10 systems, and MULTICS. The relative merits of LOGO and LISP as educational languages are discussed. ...
Hierarchical Shape Description of Objects by Selection and Modification of Prototypes
(1975-11-01)
An approach towards shape description, based on prototype modification and generalized cylinders, has been developed and applied to the object domains pottery and polyhedra: (1) A program describes and identifies pottery ...
Reasoning from Incomplete Knowledge in a Procedural Deduction System
(1975-12-01)
One very useful idea in AI research has been the notion of an explicit model of a problem situation. Procedural deduction languages, such as PLANNER, have been valuable tools for building these models. But PLANNER and its ...
A Preliminary Report on a Program for Generating Natural Language
(MIT Artificial Intelligence Laboratory, 1975-06)
A program framework has been designed in which the linguistic facts and heuristics necessary for generating fluent natural language can be encoded. The linguistic data is represented in annotated procedures and data ...
