From Genetic Algorithms to Efficient Organization
(1994-05-01)
The work described in this thesis began as an inquiry into the nature and use of optimization programs based on "genetic algorithms." That inquiry led, eventually, to three powerful heuristics that are broadly applicable ...
Forecasting Global Temperature Variations by Neural Networks
(1994-08-01)
Global temperature variations between 1861 and 1984 are forecast usingsregularization networks, multilayer perceptrons and linearsautoregression. The regularization network, optimized by stochasticsgradient descent associated ...
Asymptotically Zero Energy Computing Using Split-Level Charge Recovery Logic
(1994-06-01)
The dynamic power requirement of CMOS circuits is rapidly becoming a major concern in the design of personal information systems and large computers. In this work we present a number of new CMOS logic families, Charge ...
An Analysis of the Effect of Gaussian Error in Object Recognition
(1994-02-01)
Object recognition is complicated by clutter, occlusion, and sensor error. Since pose hypotheses are based on image feature locations, these effects can lead to false negatives and positives. In a typical recognition ...
How are Three-Deminsional Objects Represented in the Brain?
(1994-04-01)
We discuss a variety of object recognition experiments in which human subjects were presented with realistically rendered images of computer-generated three-dimensional objects, with tight control over stimulus shape, ...
The Quadric Reference Surface: Theory and Applications
(1994-06-01)
The conceptual component of this work is about "reference surfaces'' which are the dual of reference frames often used for shape representation purposes. The theoretical component of this work involves the question ...
Automated Reasoning About Classical Mechanics
(1994-05-01)
In recent years, researchers in artificial intelligence have become interested in replicating human physical reasoning talents in computers. One of the most important skills in this area is predicting how physical ...
A Nonparametric Approach to Pricing and Hedging Derivative Securities via Learning Networks
(1994-04-01)
We propose a nonparametric method for estimating derivative financial asset pricing formulae using learning networks. To demonstrate feasibility, we first simulate Black-Scholes option prices and show that learning ...
Logging and Recovery in a Highly Concurrent Database
(1994-06-01)
This report addresses the problem of fault tolerance to system failures for database systems that are to run on highly concurrent computers. It assumes that, in general, an application may have a wide distribution in ...
Computing 3-D Motion in Custom Analog and Digital VLSI
(1994-11-28)
This thesis examines a complete design framework for a real-time, autonomous system with specialized VLSI hardware for computing 3-D camera motion. In the proposed architecture, the first step is to determine point ...
