Geo-Phisher: The Design and Evaluation of Information Visualizations about Internet Phishing Trends
(IEEE, 2016-06)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, 2021-11-18)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, 2017-08-24)Request latency resulting from the geographic separation between clients and remote application servers is a challenge for cloud-hosted 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, 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, ... -
A Geometric B-Spline Over the Triangular Domain
(University of Waterloo, 2003)For modelling curves, B-splines [3] are among the most versatile control schemes. However, scaling this technique to surface patches has proven to be a non-trivial endeavor. While a suitable scheme exists for rectangular ... -
Geometric On-line Ray Searching Under Probability of Placement Scenarios
(University of Waterloo, 2010-09-28)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 ... -
Gesture-Based Image Acquisition between Smartphone and Digital Signage
(University of Waterloo, 2011-04-28)Mobile phones have formed a social network within the phone subscriber population by allowing the phone subscribers to exchange information. Nowadays, smartphones have been improved with a variety of functionalities, such ... -
Giving Meaning to Macros
(University of Waterloo, 2004)With the prevalence of legacy C/C++ code, issues of readability and maintainability have become increasingly important. When we consider the problem of refactoring or migrating C/C++ code, we see the significant role ... -
gLOP: A Cleaner Dirty Model for Multitask Learning
(University of Waterloo, 2014-08-22)Multitask learning (MTL) was originally defined by Caruana (1997) as "an approach to inductive transfer that improves learning for one task by using the information contained in the training signals of other related tasks". ... -
Gradual C Programming for Typed Lua
(University of Waterloo, 2019-01-22)The work presented in this thesis deals with the problem of enhancing the performance of dynamically-typed programming languages by integrating features from statically-typed programming languages. Statically-typed languages ... -
A Gradual Non-Convexation Penalty Method for Minimizing VaR
(University of Waterloo, 2012-05-08)This thesis investigates the portfolio optimization problem using Value-at-Risk (VaR) as a risk measure, when m sample scenarios are given. Minimizing VaR of a portfolio is computationally difficult: it is non-convex, ... -
Gradual Pluggable Typing in Java
(University of Waterloo, 2016-04-27)Gradual typing provides the ability to safely mix untyped or dynamically typed code with statically typed code while maintaining, within the statically typed portion, the guarantees claimed by the static typing. It is ... -
Graph Editing to a Given Neighbourhood Degree List is Fixed-Parameter Tractable
(University of Waterloo, 2016-10-26)Graph editing problems have a long history and have been widely studied, with applications in biochemistry and complex network analysis. They generally ask whether an input graph can be modified by inserting and deleting ... -
Graph Morphing via Orthogonal Box Drawings
(University of Waterloo, 2023-12-18)Abstract: A graph is a set of vertices, with some pairwise connections given by a set of edges. A graph drawing, such as a node-link diagram, visualizes a graph with geometric features. One of the most common forms of a ... -
Graph-Based Fracture Models for Rigid Body Explosions
(University of Waterloo, 2005)Explosions are one of the most powerful and devastating natural phenomena. The pressure front from the blast wave of an explosion can cause fracture of objects in its vicinity and create flying debris. In this thesis, ... -
Graph-Based Mapping for Knowledge Transfer in General Game Playing
(University of Waterloo, 2024-01-17)General game playing (GGP) is a field of reinforcement learning (RL) in which the rules of a game (i.e. the state and dynamics of an RL domain) are not specified until runtime. A GGP agent must therefore be able to play ... -
Graph-Based Spatial-Temporal Cluster Evolution: Representation, Analysis, and Implementation
(University of Waterloo, 2023-08-28)Spatial-temporal data are information about real-world entities that exist in a location, the spatial dimension, and during a period of time, the temporal dimension. These real-world entities, such as vehicles, people, or ... -
Graph-theoretic Properties of Control Flow Graphs and Applications
