Defining Natural Language Grammars in GPSG
(1986-04-01)
This paper is a formal analysis of whether generalized phrase structure grammar's (GPSG) weak context-free generative power will allow it to achieve three of its central goals: (1) to characterize all and only the ...
Discovery Systems
(1986-04-01)
Cyrano is a thoughtful reimplementation of Lenat's controversial Eurisko program, designed to perform automated discovery and concept formation in a variety of technical fields. The 'thought' in the reimplementation ...
An Approach To Object Recognition: Aligning Pictorial Descriptions
(1986-12-01)
This paper examines the problem of shape-based object recognition and proposes a new approach, the alignment of pictorial descriptions. The first part of the paper reviews general approaches to visual object recognition ...
Probabilistic Solution of Ill-Posed Problems in Computational Vision
(1987-03-01)
We formulate several problems in early vision as inverse problems. Among the solution methods we review standard regularization theory, discuss its limitations, and present new stochastic (in particular, Bayesian) ...
A Simple Motion Planning Algorithm for General Robot Manipulators
(1986-06-01)
This paper presents a simple and efficient algorithm, using configuration space, to plan collision-free motions for general manipulators. We describe an implementation of the algorithm for manipulators made up of ...
Simplifying Decision Trees
(1986-12-01)
Many systems have been developed for constructing decision trees from collections of examples. Although the decision trees generated by these methods are accurate and efficient, they often suffer the disadvantage of ...
Achieving Artificial Intelligence through Building Robots
(1986-05-01)
We argue that generally accepted methodologies of Artificial Intelligence research are limited in the proportion of human level intelligence they can be expected to emulate. We argue that the currently accepted ...
The Programmer's Apprentice: A Program Design Scenario
(1987-11-01)
A scenario is used to illustrate the capabilities of a proposed Design Apprentice, focussing on the area of detailed, low-level design. Given a specification, the Design Apprentice will be able to make many of the ...
A Lexical Conceptual Approach to Generation for Machine Translation
(1988-01-01)
Current approaches to generation for machine translation make use of direct-replacement templates, large grammars, and knowledge-based inferencing techniques. Not only are rules language-specific, but they are too ...
Visual Integration and Detection of Discontinuities: The Key Role of Intensity Edges
(1987-10-01)
Integration of several vision modules is likely to be one of the keys to the power and robustness of the human visual system. The problem of integrating early vision cues is also emerging as a central problem in current ...
