Towards a Computational Theory of Definite Anaphora Comprehension in English Discourse
(1979-06-01)
This report investigates the process of focussing as a description and explanation of the comprehension of certain anaphoric expressions in English discourse. The investigation centers on the interpretation of definite ...
Causal and Teleological Reasoning in Circuit Recognition
(1979-09-01)
This thesis presents a theory of human-like reasoning in the general domain of designed physical systems, and in particular, electronic circuits. One aspect of the theory, causal analysis, describes how the behavior ...
A Numerical Method for Shape-From-Shading From A Single Image
(MIT Artificial Intelligence Laboratory, 1979-01)
The shape of an object can be determined from the shading in a single image by solving a first-order, non-linear partial differential equation. The method of characteristics can be used to do this, but it suffers from a ...
Conceptual Phrases and Deterministic English Parsing
(MIT Artificial Intelligence Laboratory, 1979-08)
The grammar of many of the lower-level constituents of grammatical structures in English has not been a area of exciting new linguistic discovery, in contrast with study of clause-level constituents. The syntax of these ...
Logical Control Theory Applied to Mechanical Arms
(MIT Artificial Intelligence Laboratory, 1979-02)
A new control algorithm based upon Logical Control Theory is developed for mechanical manipulators. The controller uses discrete tesselations of state space and a finite set of fixed torques to regulate non-rehearsed ...
The Use of Thread Memory in Amnesic Aphasia and Concept Learning.(note 0)
(MIT Artificial Intelligence Laboratory, 1979-09-05)
We propose a new type of semantic memory, called thread memory. The primitives of this memory are threads, defined as keyed multilink, loop-free chains, which link semantic nodes. All links run from superordinate categories ...
Steps Toward a Psycholinguistic Model of Language Production
(MIT Artificial Intelligence Laboratory, 1979-04)
This paper discusses what it would mean to have a psychological model of the language production process: what such a model would have to account for, what it would use as evidence. It outlines and motivates one particular ...
Differential Geometry, Surface Patches and Convergence Methods
(1979-02-01)
The problem of constructing a surface from the information provided by the Marr-Poggio theory of human stereo vision is investigated. It is argued that not only does this theory provide explicit boundary conditions at ...
Computer Aided Evolutionary Design for Digital Integrated Systems
(1979-05-01)
We propose to develop a computer aided design tool which can help an engineer deal with system evolution from the initial phases of design right through the testing and maintenance phases. We imagine a design system ...
The Dream of a Lifetime: A Lazy Scoping Mechanism
(1979-11-01)
We define a "rack", a data abstraction hybrid of a register and a stack. It is used for encapsulating the behavior of the kind of register whose contents may have an extent which requires that it be saved during the ...
