Intelligence in Scientific Computing
(1988-11-01)
Combining numerical techniques with ideas from symbolic computation and with methods incorporating knowledge of science and mathematics leads to a new category of intelligent computational tools for scientists and ...
The Last Whole XGP Font Catalog
(MIT Artificial Intelligence Laboratory, 1980-03)
A Colony Architecture for an Artificial Creature
(1989-09-01)
This report describes a working autonomous mobile robot whose only goal is to collect and return empty soda cans. It operates in an unmodified office environment occupied by moving people. The robot is controlled by a ...
Three-Dimensional Motion Estimation Using Shading Information in Multiple Frames
(1989-09-01)
A new formulation for recovering the structure and motion parameters of a moving patch using both motion and shading information is presented. It is based on a new differential constraint equation (FICE) that links the ...
Switching Between Discrete and Continuous Process Models to Predict Molecular Genetic Activity
(1984-05-01)
Two kinds of process models have been used in programs that reason about change: Discrete and continuous models. We describe the design and implementation of a qualitative simulator, PEPTIDE, which uses both kinds of ...
On Motion Planning with Uncertainty
(1984-08-01)
Robots must successfully plan and execute tasks in the presence of uncertainty. Uncertainty arises from errors in modeling, sensing, and control. Planning in the presence of uncertainty constitutes one facet of the ...
Justified Generalization: Acquiring Procedures from Examples
(1985-01-01)
This thesis describes an implemented system called NODDY for acquiring procedures from examples presented by a teacher. Acquiring procedures form examples involves several different generalization tasks. Generalization ...
Principle-Based Parsing
(1987-06-01)
During the past few years, there has been much discussion of a shift from rule-based systems to principle-based systems for natural language processing. This paper outlines the major computational advantages of ...
An O(N) Algorithm for Three-Dimensional N-Body Simulations
(1987-10-01)
We develop an algorithm that computes the gravitational potentials and forces on N point-masses interacting in three-dimensional space. The algorithm, based on analytical techniques developed by Rokhlin and Greengard, ...
UNITRAN: A Principle-Based Approach to Machine Translation
(1987-12-01)
Machine translation has been a particularly difficult problem in the area of Natural Language Processing for over two decades. Early approaches to translation failed since interaction effects of complex phenomena in ...
