Wholetoning: Synthesizing Abstract Black-and-White Illustrations
(University of Waterloo, 2009-02-18)
Black-and-white imagery is a popular and interesting depiction technique in the visual arts, in which varying tints and shades of a single colour are used. Within the realm of black-and-white images, there is a set of ...
Access Control Administration with Adjustable Decentralization
(University of Waterloo, 2007-09-12)
Access control is a key function of enterprises that preserve and propagate massive data. Access control enforcement and administration are two major components of the system. On one hand, enterprises are responsible for ...
A Formalism for Visual Query Interface Design
(University of Waterloo, 2009-01-15)
The massive volumes and the huge variety of large knowledge bases make information
exploration and analysis difficult. An important activity is data filtering and
selection, in which both querying and visualization play ...
Subjective Mapping
(University of Waterloo, 2007-11-20)
There are a variety of domains where it is desirable to learn a representation
of an environment defined by a stream of sensori-motor experience. This
dissertation introduces and formalizes subjective mapping, a novel ...
Aspects of Metric Spaces in Computation
(University of Waterloo, 2008-06-06)
Metric spaces, which generalise the properties of commonly-encountered physical and abstract spaces into a mathematical framework, frequently occur in computer science applications. Three major kinds of questions about ...
Direct and Expressive Type Inference for the Rank 2 Fragment of System F
(University of Waterloo, 2007-09-20)
This thesis develops a semiunification-based type inference procedure for the rank 2 fragment of System F, with an emphasis on practical considerations for the adoption of such a procedure into existing programming ...
Frameworks for Quantum Algorithms
(University of Waterloo, 2014-08-26)
Due to the difficulty of constructing new quantum algorithms, frameworks that facilitate this construction are of great importance in quantum computing. These frameworks reduce the problem of coming up with a quantum ...
Geometric Approximation Algorithms in the Online and Data Stream Models
(University of Waterloo, 2008-10-23)
The online and data stream models of computation have recently attracted considerable research attention due to many real-world applications in various areas such as data mining, machine learning, distributed computing, ...
Subseries Join and Compression of Time Series Data Based on Non-uniform Segmentation
(University of Waterloo, 2008-09-24)
A time series is composed of a sequence of data items that are measured at uniform intervals. Many application areas generate or manipulate time series, including finance, medicine, digital audio, and motion capture. ...
Probabilistic Graphical Models and Algorithms for
(University of Waterloo, 2008-05-26)
In this thesis I present research in two fields: machine learning and computational biology.
First, I develop new machine learning methods for graphical models that can be applied to protein problems. Then I apply ...
