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 ...
The Variational Approach to Shape from Shading
(1985-03-01)
We develop a systematic approach to the discovery of parallel iterative schemes for solving the shape-from-shading problem on a grid. A standard procedure for finding such schemes is outlines, and subsequently used ...
The Use of Censors for Nonmonotonic Reasoning and Analogy in Medical Desicion-Making
(1985-11-01)
A patient rarely has a single, isolated disease. The situation is usually much more complex since the different parts of the human organism and metabolism interact with each other and follow several feedback patterns. ...
Biophysics of Computation: Neurons, Synapses and Membranes
(1984-10-01)
Synapses, membranes and neurotransmitters play an important role in processing information in the nervous system. We do not know, however, what biophysical mechanisms are critical for neuronal computations, what ...
