Music, Mind and Meaning
(1981-02-01)
Speculating about cognitive aspects of listening to music, this essay discusses: how metric regularity and thematic repetition might involve representation frames and memory structures, how the result of listening might ...
Solving Uninterpreted Equations with Context Free Expression Grammars
(1983-05-01)
It is shown here that the equivalence class of an expression under the congruence closure of any finite set of equations between ground terms is a context free expression language. An expression is either a symbols or ...
Symmetric Set Theory: A General Theory of Isomorphism, Abstraction, and Representation
(1983-08-01)
It is possible to represent a finite set of points (atoms) by a finite sequence of points. However a finite set of points has no distinguished member and therefore it is impossible to define a function which takes a ...
Information Processing in Dendritic Spines
(1983-03-01)
Dendritic spines are small twigs on the dendrites of a very large class of neurons in the central nervous system. There are between 10 (3) and 10 (5) spines per neuron, each one including at least one synapse, i.e. a ...
Computational Studies in the Interpretation of Structure and Motion: Summary and Extension
(1983-03-01)
Computational studies of the interpretation of structure from motion examine the conditions under which three-dimensional structure can be recovered from motion in the image. The first part of this paper summarizes the ...
Tactile Recognition and Localization Using Object Models: The Case of Polyhedra on a Plane
(1983-03-01)
This paper discusses how data from multiple tactile sensors may be used to identify and locate one object, from among a set of known objects. We use only local information from sensors: (1) the position of contact ...
Computational Introspection
(1983-02-01)
Introspection is the process of thinking about one's own thoughts and feelings. In this paper, I discuss recent attempts to make computational systems that exhibit introspective behavior: [Smith, 982], [Weyhrauch, ...
Representations for Reasoning About Change
(1983-04-01)
This paper explores representations used to reason about objects which change over time and the processes which cause changes. Specifically, we are interested in solving a problem known as geologic interpretation. To ...
An Extremum Principle for Shape from Contour
(1983-06-01)
An extremum principle is developed that determines three-dimensional surface orientation from a two-dimensional contour. The principle maximizes the ratio of the area to the square of the perimeter, a measure of the ...
Dynamic Scaling of Manipulator Trajectories
(1983-01-01)
A fundamental time-scaling property of manipulator dynamics has been identified that allows modification of movement speed without complete dynamics recalculation. By exploiting this property, it can be determined ...
