Computational Consequences of Agreement and Ambiguity in Natural Language
(1988-11-01)
The computer science technique of computational complexity analysis can provide powerful insights into the algorithm-neutral analysis of information processing tasks. Here we show that a simple, theory-neutral linguistic ...
Olympic Robot Building Manual
(1988-12-01)
The 1989 AI Lab Winter Olympics will take a slightly different twist from previous Olympiads. Although there will still be a dozen or so athletic competitions, the annual talent show finale will now be a display not ...
Seeing 'Ghost' Solutions in Stereo Vision
(1988-09-01)
A unique matching is a stated objective of most computational theories of stereo vision. This report describes situations where humans perceive a small number of surfaces carried by non-unique matching of random dot ...
Model-Based Troubleshooting of Digital Systems
(1988-08-01)
This thesis describes a methodology, a representation, and an implemented program for troubleshooting digital circuit boards at roughly the level of expertise one might expect in a human novice. Existing methods for ...
A Concurrent Smalltalk Compiler for the Message-Driven Processor
(1988-05-01)
This thesis describes Optimist, an optimizing compiler for the Concurrent Smalltalk language developed by the Concurrent VLSI Architecture Group. Optimist compiles Concurrent Smalltalk to the assembly language of the ...
Modeling Robot Dynamic Performance for Endpoint Force Control
(1988-09-01)
This research aims to understand the fundamental dynamic behavior of servo-controlled machinery in response to various types of sensory feedback. As an example of such a system, we study robot force control, a scheme ...
The Use of Grouping in Visual Object Recognition.
(1988-01-01)
The report describes a recognition system called GROPER, which performs grouping by using distance and relative orientation constraints that estimate the likelihood of different edges in an image coming from the same ...
Boundaries and Topological Algorithms
(1988-09-01)
This thesis develops a model for the topological structure of situations. In this model, the topological structure of space is altered by the presence or absence of boundaries, such as those at the edges of objects. ...
Task-Level Robot Learning
(1988-08-01)
We are investigating how to program robots so that they learn from experience. Our goal is to develop principled methods of learning that can improve a robot's performance of a wide range of dynamic tasks. We have ...
Scale effects in tests on footings
(University of CambridgeChrist's College, 1988-02-21)
This dissertation presents an investigation of the effects of stress, and of absolute and
relative particle size, in tests on vertically loaded footings. Two granular materials, namely, a silica rock flour and a Chatelet ...
