Automatic Qualitative Analysis of Ordinary Differential Equations Using Piecewise Linear Approximations
(1988-03-01)
This paper explores automating the qualitative analysis of physical systems. It describes a program, called PLR, that takes parameterized ordinary differential equations as input and produces a qualitative description of ...
Combining Associational and Causal Reasoning to Solve Interpretation and Planning Problems
(1988-08-01)
This report describes a paradigm for combining associational and causal reasoning to achieve efficient and robust problem-solving behavior. The Generate, Test and Debug (GTD) paradigm generates initial hypotheses using ...
Theories of Comparative Analysis
(1988-05-01)
Comparative analysis is the problem of predicting how a system will react to perturbations in its parameters, and why. For example, comparative analysis could be asked to explain why the period of an oscillating ...
Three-Dimensional Recognition of Solid Objects from a Two-Dimensional Image
(1988-10-01)
This thesis addresses the problem of recognizing solid objects in the three-dimensional world, using two-dimensional shape information extracted from a single image. Objects can be partly occluded and can occur in ...
Heuristics for Job-Shop Scheduling
(1988-01-01)
Two methods of obtaining approximate solutions to the classic General Job-shop Scheduling Program are investigated. The first method is iterative. A sampling of the solution space is used to decide which of a collection ...
Computation and Pre-Parametric Design
(1988-09-01)
My work is broadly concerned with the question "How can designs bessynthesized computationally?" The project deals primarily with mechanical devices and focuses on pre-parametric design: design at the level of detail ...
A Circuit Grammar For Operational Amplifier Design
(1984-01-01)
Electrical circuit designers seldom create really new topologies or use old ones in a novel way. Most designs are known combinations of common configurations tailored for the particular problem at hand. In this thesis ...
Hierarchical Object Recognition Using Libraries of Parameterized Model Sub-Parts
(1987-05-01)
This thesis describes the development of a model-based vision system that exploits hierarchies of both object structure and object scale. The focus of the research is to use these hierarchies to achieve robust recognition ...
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 ...
