A 2-Approximation for the Height of Maximal Outerplanar Graph Drawings
(University of Waterloo, 2016-08-18)In this thesis, we study drawings of maximal outerplanar graphs that place vertices on integer coordinates. We introduce a new class of graphs, called umbrellas, and a new method of splitting maximal outerplanar graphs ... -
3-D Reconstruction from Single Projections, with Applications to Astronomical Images
(University of Waterloo, 2013-08-23)A variety of techniques exist for three-dimensional reconstruction when multiple views are available, but less attention has been given to reconstruction when only a single view is available. Such a situation is normal in ... -
3D Online Multi-Object Tracking for Autonomous Driving
(University of Waterloo, 2019-08-29)This research work focuses on exploring a novel 3D multi-object tracking architecture: 'FANTrack: 3D Multi-Object Tracking with Feature Association Network' for autonomous driving, based on tracking by detection and online ... -
5G RAN/MEC Slicing and Admission Control using Deep Reinforcement Learning
(University of Waterloo, 2023-01-19)The 5G RAN functions can be virtualized and distributed across the radio unit (RU), distributed unit (DU), and centralized unit (CU) to facilitate flexible resource management. Complemented by multi-access edge computing ... -
A+ Indexes: Highly Flexible Adjacency Lists in Graph Database Management Systems
(University of Waterloo, 2019-09-17)Adjacency lists are the most fundamental storage structure in existing graph database management systems (GDBMSs) to index input graphs. Adjacency lists are universally linked-list like per-vertex structures that allow ... -
Accelerating the Training of Convolutional Neural Networks for Image Segmentation with Deep Active Learning
(University of Waterloo, 2020-01-23)Image semantic segmentation is an important problem in computer vision. However, Training a deep neural network for semantic segmentation in supervised learning requires expensive manual labeling. Active learning (AL) ... -
Achieving Performance Objectives for Database Workloads
(University of Waterloo, 2010-08-30)In this thesis, our goal is to achieve customer-specified performance objectives for workloads in a database management system (DBMS). Competing workloads in current DBMSs have detrimental effects on performance. ... -
Active Learning with Semi-Supervised Support Vector Machines
(University of Waterloo, 2007-05-22)A significant problem in many machine learning tasks is that it is time consuming and costly to gather the necessary labeled data for training the learning algorithm to a reasonable level of performance. In reality, it is ... -
Active Sensing for Partially Observable Markov Decision Processes
(University of Waterloo, 2013-01-21)Context information on a smart phone can be used to tailor applications for specific situations (e.g. provide tailored routing advice based on location, gas prices and traffic). However, typical context-aware smart phone ... -
Ad-hoc Holistic Ranking Aggregation
(University of Waterloo, 2012-12-06)Data exploration is considered one of the major processes that enables the user to analyze massive amount of data in order to find the most important and relevant informa- tion needed. Aggregation and Ranking are two of ... -
Adapting Component Analysis
(University of Waterloo, 2012-05-18)A main problem in machine learning is to predict the response variables of a test set given the training data and its corresponding response variables. A predictive model can perform satisfactorily only if the training ... -
Adapting to Data Drift in Encrypted Traffic Classification Using Deep Learning
(University of Waterloo, 2023-01-12)Deep learning models have shown to achieve high performance in encrypted traffic classification. However, when it comes to production use, multiple factors challenge the performance of these models. The emergence of new ... -
Adaptive Algorithms for Weighted Queries on Weighted Binary Relations and Labeled Trees
(University of Waterloo, 2007-07-30)Keyword queries are extremely easy for a user to write. They have become a standard way to query for information in web search engines and most other information retrieval systems whose users are usually laypersons and ... -
Adaptive Comparison-Based Algorithms for Evaluating Set Queries
(University of Waterloo, 2004)In this thesis we study a problem that arises in answering boolean queries submitted to a search engine. Usually a search engine stores the set of IDs of documents containing each word in a pre-computed sorted order and ... -
An Adaptive Context-Aware Publish–Subscribe Component Metamodel
(University of Waterloo, 2015-01-16)There are plenty of solutions in which the functionality for context awareness is separated from the domain-specific functionality. Also, there are multiple ways of modeling, gathering, and processing context-related ... -
Adaptive Cross-Project Bug Localization with Graph Learning
(University of Waterloo, 2022-06-07)Bug localization is the process of identifying the source code files associated with a bug report. This is important because it allows developers to focus their efforts on fixing the bugs than finding the root cause of ... -
Adaptive Fusion Techniques for Effective Multimodal Deep Learning
(University of Waterloo, 2020-08-28)Effective fusion of data from multiple modalities, such as video, speech, and text, is a challenging task due to the heterogeneous nature of multimodal data. In this work, we propose fusion techniques that aim to model ... -
Adaptive Range Counting and Other Frequency-Based Range Query Problems
(University of Waterloo, 2012-05-18)We consider variations of range searching in which, given a query range, our goal is to compute some function based on frequencies of points that lie in the range. The most basic such computation involves counting the ... -
Adding Reference Immutability to Scala
(University of Waterloo, 2023-07-10)Scala is a multi-paradigm programming language combining the power of functional and object-oriented programming. While Scala has many features promoting immutability, it lacks a built-in mechanism for controlling and ... -
