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 ...
Model-Based Reasoning: Troubleshooting
(1988-07-01)
To determine why something has stopped working, it is useful to know how it was supposed to work in the first place. That simple observation underlies some of the considerable interest generated in recent years on the topic ...
Analysis of Differential and Matching Methods for Optical Flow
(1988-08-01)
Several algorithms for optical flow are studied theoretically and experimentally. Differential and matching methods are examined; these two methods have differing domains of application- differential methods are best ...
Demystifying Quantum Mechanics: A Simple Universe with Quantum Uncertainty
(1988-12-01)
An artificial universe is defined that has entirely deterministic laws with exclusively local interactions, and that exhibits the fundamental quantum uncertainty phenomenon: superposed states mutually interfere, but ...
Herbert: A Second Generation Mobile Robot
(1988-01-01)
In mobile robot research we believe the structure of the platform, its capabilities, the choice of sensors, their capabilities, and the choice of processors, both onboard and offboard, greatly constrains the direction of ...
The Combinatorics of Object Recognition in Cluttered Environments Using Constrained Search
(1988-02-01)
When clustering techniques such as the Hough transform are used to isolate likely subspaces of the search space, empirical performance in cluttered scenes improves considerably. In this paper we establish formal bounds ...
Structural Saliency: The Detection of Globally Salient Structures Using a Locally Connected Network
(1988-07-01)
Certain salient structures in images attract our immediate attention without requiring a systematic scan. We present a method for computing saliency by a simple iterative scheme, using a uniform network of locally ...
