Specialization of Perceptual Processes
(1995-04-22)
In this report, I discuss the use of vision to support concrete, everyday activity. I will argue that a variety of interesting tasks can be solved using simple and inexpensive vision systems. I will provide a number ...
Learning World Models in Environments with Manifest Causal Structure
(1995-05-05)
This thesis examines the problem of an autonomous agent learning a causal world model of its environment. Previous approaches to learning causal world models have concentrated on environments that are too "easy" ...
A Radial Basis Function Approach to Financial Time Series Analysis
(1993-12-01)
Nonlinear multivariate statistical techniques on fast computers offer the potential to capture more of the dynamics of the high dimensional, noisy systems underlying financial markets than traditional models, while ...
The Named-State Register File
(1993-08-01)
This thesis introduces the Named-State Register File, a fine-grain, fully-associative register file. The NSF allows fast context switching between concurrent threads as well as efficient sequential program performance. ...
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 ...
SodaBot: A Software Agent Environment and Construction System
(1994-11-02)
This thesis presents SodaBot, a general-purpose software agent user-environment and construction system. Its primary component is the basic software agent --- a computational framework for building agents which is ...
Methods for Parallelizing Search Paths in Phrasing
(1994-01-01)
Many search problems are commonly solved with combinatoric algorithms that unnecessarily duplicate and serialize work at considerable computational expense. There are techniques available that can eliminate redundant ...
Naive Physics, Event Perception, Lexical Semantics, and Language Acquisition
(1993-04-01)
This thesis proposes a computational model of how children may come to learn the meanings of words in their native language. The proposed model is divided into two separate components. One component produces semantic ...
Automatic Analysis and Synthesis of Controllers for Dynamical Systems Based On P
(1992-09-01)
I present a novel design methodology for the synthesis of automatic controllers, together with a computational environment---the Control Engineer's Workbench---integrating a suite of programs that automatically analyze ...
