Computational Complexity of Current GPSG Theory
(1986-04-01)
An important goal of computational linguistics has been to use linguistic theory to guide the construction of computationally efficient real-world natural language processing systems. At first glance, the entirely new ...
Hermeneutics: From Textual Explication to Computer Understanding?
(1986-05-01)
Hermeneutics, a branch of continental European philosophy concerned with human understanding and the interpretation of written texts, offers insights that may contribute to the understanding of meaning, translation, ...
Direct Passive Navigation: Analytical Solution for Quadratic Patches
(1986-03-01)
In this paper, we solve the problem of recovering the motion of an observer relative to a surface which can be locally approximated by a quadratic patch directly from image brightness values. We do not compute the ...
Classifying Objects from Visual Information
(1986-06-01)
Consider a world of 'objects.' Our goal is to place these objects into categories that are useful to the observer using sensory data. One criterion for utility is that the categories allow the observer to infer the ...
Genetic AI: Translating Piaget into Lisp
(1986-02-01)
This paper presents a constuctivist model of human cognitive development during infancy. According to constructivism, the elements of mental representation -- even such basic elements as the concept of physical object ...
Spatio-Temporal Reasoning and Linear Inequalities
(1986-05-01)
Time and space are sufficiently similar to warrant in certain cases a common representation in AI problem-solving systems. What is represented is often the constraints that hold between objects, and a concern is the ...
The Outer Solar System for 210 Million Years
(1986-02-01)
We used a special purpose computer to integrate the orbits of the outer five planets for 100 Myr into the future and 100 Myr into the past. The strongest features in the Fourier transforms of the orbital elements of ...
ARLO: Another Representation Language Offer
(1986-10-01)
This paper describes ARLO, a representation language loosely modelled after Greiner and Lenant's RLL-1. ARLO is a structure-based representation language for describing structure-based representation languages, including ...
The Synthesis of Stable Force-Closure Grasps
(1986-07-01)
This thesis addresses the problem of synthesizing grasps that are force-closure and stable. The synthesis of force-closure grasps constructs independent regions of contact for the fingertips, such that the motion of ...
Learning by Failing to Explain
(1986-05-01)
Explanation-based Generalization requires that the learner obtain an explanation of why a precedent exemplifies a concept. It is, therefore, useless if the system fails to find this explanation. However, it is not ...
