Thinking About Lots of Things at Once without Getting Confused: Parallelism in Act 1
(1981-05-01)
As advances in computer architecture and changing economics make feasible machines with large-scale parallelism, Artificial Intelligence will require new ways of thinking about computation that can exploit parallelism ...
Active Touch Sensing
(1981-04-01)
The mechanical hand of the future will roll a screw between its fingers and sense, by touch, which end is which. This paper describes a step toward such a manipulator ?? robot finger that is used to recognize small ...
A Preview of Act 1
(1981-06-01)
The next generation of artificial intelligence programs will require the ability to organize knowledge as groups of active objects. Each object should have only its own local expertise, the ability to operate in parallel ...
The Use of Parallelism to Implement a Heuristic Search
(1981-03-01)
The role of parallel processing in heuristic search is examined by means of an example (cryptarithmetic addition). A problem solver is constructed that combines the metaphors of constraint propagation and hypothesize-and-test. ...
Chaosnet
(1981-06-01)
Chaosnet is a local network, that is, a system for communication among a group of computers located within about 1000 meters of each other. Originally developed by the Artificial Intelligence Laboratory as the internal ...
A Theoretical Analysis of Electrical Properties of Spines
(1983-04-01)
The electrical properties of a cortical (spiny) pyramidal cell were analyzed on the basis of passive cable theory from measurements made on histological material (Koch, Poggio & Torre 1982). The basis of this analysis ...
The Computation of the Velocity Field
(1983-09-01)
The organization of movement in the changing retinal image provides a valuable source of information for analyzing the environment in terms of objects, their motion in space and their three-dimensional structure. A ...
Fingerprints Theorems for Zero-Crossings
(1983-10-01)
We prove that the scale map of the zero-crossings of almost all signals filtered by the second derivative of a gaussian of variable size determines the signal uniquely, up to a constant scaling and a harmonic function. ...
Parts of Recognition
(1983-12-01)
A complete theory of object recognition is an impossibility ??t simply because of the multiplicity of visual cues we exploit in elegant coordination to identify an object, but primarily because recognition involves ...
Determining Attitude of Object from Needle Map Using Extended Gaussian Image
(1983-04-01)
An extended Gaussian image (EGI) is constructed by mapping the surface normals of an object onto the Gussian sphere. The attitude of an object is greatly constrained by the global distribution of EGI mass over the ...
