The Generalized Method of Moments for Mixture and Mixed Models
(University of Waterloo, 20150928)Mixture models can be found in a wide variety of statistical applications. However, undertaking statistical inference in mixture models, especially nonparametric mixture models, can be challenging. A general, or nonparametric, ... 
Generalized Set and Graph Packing Problems
(University of Waterloo, 20151112)Many complex systems that exist in nature and society can be expressed in terms of networks (e.g., social networks, communication networks, biological networks, Web graph, among others). Usually a node represents an ... 
Generalized Strategies for Path Integration using Neural Oscillators
(University of Waterloo, 20140820)Path integration is a process by which an animal obtains its location by integrating its velocity over time. Evidence shows that path integration may contribute to certain neural activity patterns in the entorhinal cortex ... 
Generalizing sampling theory for timevarying Nyquist rates using selfadjoint extensions of symmetric operators with deficiency indices (1,1) in Hilbert spaces
(University of Waterloo, 20110930)Sampling theory studies the equivalence between continuous and discrete representations of information. This equivalence is ubiquitously used in communication engineering and signal processing. For example, it allows ... 
Generating Functions for Hyperbolic Plane Tessellations
(University of Waterloo, 20170828)For a hyperbolic plane tessellation there is a generating function with respect to the distance. This generating function is the same as the growth function of a group of isometries of hyperbolic plane that acts regularly ... 
Generating patterns on clothing for seamless design
(University of Waterloo, 20210426)Symmetric patterns are used widely in clothing manufacture. However, the discontinuity of patterns at seams can disrupt the visual appeal of clothing. While it is possible to align patterns to conceal such pattern breaks, ... 
Generating Radiosity Maps on the GPU
(University of Waterloo, 2005)Global illumination algorithms are used to render photorealistic images of 3D scenes taking into account both direct lighting from the light source and light reflected from other surfaces in the scene. Algorithms based ... 
Generation and properties of random graphs and analysis of randomized algorithms
(University of Waterloo, 20100122)We study a new method of generating random $d$regular graphs by repeatedly applying an operation called pegging. The pegging algorithm, which applies the pegging operation in each step, is a method of generating large ... 
Generative Modeling with Neural Ordinary Differential Equations
(University of Waterloo, 20191219)Neural ordinary differential equations (NODEs) (Chen et al., 2018) are ordinary differential equations (ODEs) with their dynamics modeled by neural networks. Continuous normalizing flows (CNFs) (Chen et al., 2018; Grathwohl ... 
Generic Attacks on Hash Functions
(University of Waterloo, 20100928)The subject of this thesis is a security property of hash functions, called chosentarget forcedprefix preimage (CTFP) resistance and the generic attack on this property, called the herding attack. The study of CTFP ... 
Genetic Programming for the Evolution of Functions with a Discrete Unbounded Domain
(University of Waterloo, 20130516)The idea of automatic programming using the genetic programming paradigm is a concept that has been explored in the work of Koza and several works since. Most problems attempted using genetic programming are finite in size, ... 
Genus one partitions
(University of Waterloo, 2006)We obtain a tight upper bound for the genus of a partition, and calculate the number of partitions of maximal genus. The generating series for genus zero and genus one rooted hypermonopoles is obtained in closed form ... 
GeoPhisher: The Design and Evaluation of Information Visualizations about Internet Phishing Trends
(IEEE, 201606)We designed an information visualization about phishing trends and phishing prevention for the general public to examine the effects of interactivity on information finding, user perceptions and security behaviour intentions, ... 
Geodesic Convex Analysis of Group Scaling for the Paulsen Problem and the Tensor Normal Model
(University of Waterloo, 20211118)The framework of scaling problems has recently had much interest in the theoretical computer science community due to its variety of applications, from algebraic complexity to machine learning. In this thesis, our main ... 
Geographically Distributed Database Management at the Cloud's Edge
(University of Waterloo, 20170824)Request latency resulting from the geographic separation between clients and remote application servers is a challenge for cloudhosted web and mobile applications. Numerous studies have shown the importance of low latency ... 
A Geometric Approach to Pattern Matching in Polyphonic Music
(University of Waterloo, 2005)The music pattern matching problem involves finding matches of a small fragment of music called the "pattern" into a larger body of music called the "score". We represent music as a series of horizontal line segments in ... 
Geometric Approximation Algorithms in the Online and Data Stream Models
(University of Waterloo, 20081023)The online and data stream models of computation have recently attracted considerable research attention due to many realworld applications in various areas such as data mining, machine learning, distributed computing, ... 
A Geometric BSpline Over the Triangular Domain
(University of Waterloo, 2003)For modelling curves, Bsplines [3] are among the most versatile control schemes. However, scaling this technique to surface patches has proven to be a nontrivial endeavor. While a suitable scheme exists for rectangular ... 
Geometric Online Ray Searching Under Probability of Placement Scenarios
(University of Waterloo, 20100928)Online computation is a model for formulating decision making under uncertainty. In an online problem, the algorithm does not know the entire input from the beginning; the input is revealed in a sequence of steps. At each ... 
Geometric Ramifications of the Lovász Theta Function and Their Interplay with Duality
(University of Waterloo, 20130830)The Lovasz theta function and the associated convex sets known as theta bodies are fundamental objects in combinatorial and semidefinite optimization. They are accompanied by a rich duality theory and deep connections ...
