A Convergent Hierarchy of Certificates for Constrained Signomial Positivity
(University of Waterloo, 2020-09-24)Optimization is at the heart of many engineering problems. Many optimization problems, however, are computationally intractable. One approach to tackle such intractability is to find a tractable problem whose solution, ... -
The Conversion of the Anglo-Saxon Laity, 597-798
(University of Waterloo, 2021-04-30)Conversion in the middle ages was driven by many factors depending on the time and place the conversion was occurring. This is often wrongly summarized by explaining that once a king converted his subjects would follow ... -
Convex Algebraic Geometry Approaches to Graph Coloring and Stable Set Problems
(University of Waterloo, 2021-08-23)The objective of a combinatorial optimization problem is to find an element that maximizes a given function defined over a large and possibly high-dimensional finite set. It is often the case that the set is so large that ... -
Convex duality in constrained mean-variance portfolio optimization under a regime-switching model
(University of Waterloo, 2008-09-23)In this thesis, we solve a mean-variance portfolio optimization problem with portfolio constraints under a regime-switching model. Specifically, we seek a portfolio process which minimizes the variance of the terminal ... -
Convex Large Margin Training - Unsupervised, Semi-supervised, and Robust Support Vector Machines
(University of Waterloo, 2007-05-22)Support vector machines (SVMs) have been a dominant machine learning technique for more than a decade. The intuitive principle behind SVM training is to find the maximum margin separating hyperplane for a given set of ... -
Convex Optimization and Utility Theory: New Trends in VLSI Circuit Layout
(University of Waterloo, 1999)The design of modern integrated circuits is overwhelmingly complicated due to the enormous number of cells in a typical modern circuit. To deal with this difficulty, the design procedure is broken down into a set of ... -
Convex Optimization via Domain-Driven Barriers and Primal-Dual Interior-Point Methods
(University of Waterloo, 2017-08-24)This thesis studies the theory and implementation of infeasible-start primal-dual interior-point methods for convex optimization problems. Convex optimization has applications in many fields of engineering and science such ... -
Convex Optimization, Stochastic Approximation, and Optimal Contract Management in Real-time Bidding
(University of Waterloo, 2022-06-02)This thesis studies problems at the intersection of monotone and convex optimization, auction theory, and electronic commerce. Convex optimization and the theory of stochastic approximation serve as the basic practical ... -
Convex relaxation for the planted clique, biclique, and clustering problems
(University of Waterloo, 2011-08-24)A clique of a graph G is a set of pairwise adjacent nodes of G. Similarly, a biclique (U, V ) of a bipartite graph G is a pair of disjoint, independent vertex sets such that each node in U is adjacent to every node in V ... -
Convex Stochastic Control and Conjugate Duality in a Problem of Unconstrained Utility Maximization Under a Regime Switching Model
(University of Waterloo, 2015-05-22)In this thesis, we examine a problem of convex stochastic optimal control applied to mathematical finance. The goal is to maximize the expected utility from wealth at close of trade (or terminal wealth) under a regime ... -
Convolutional Neural Network for Sentence Classification
(University of Waterloo, 2015-08-26)The goal of a Knowledge Base–supported Question Answering (KB-supported QA) system is to answer a query natural language by obtaining the answer from a knowledge database, which stores knowledge in the form of (entity, ... -
A Convolutional Neural Network to Predict the State-of-Lithiation of Lithium-ion Batteries with the Nickel-Manganese-Cobalt-Oxide Chemistry
(University of Waterloo, 2023-04-14)A machine learning (ML) model was developed to study the discharge behavior of a 𝐿𝑖x𝑁𝑖0.33𝑀𝑛0.33𝐶𝑜0.33𝑂2 half-cell with particle-scale resolution. The ML model could predict the state-of-lithiation of the particles ... -
Convolutional Neural Networks for Land-cover Classification Using Multispectral Airborne Laser Scanning Data
(University of Waterloo, 2018-09-21)With the spread of urban culture, urbanisation is progressing rapidly and globally. Accurate and update land cover (LC) information becomes increasingly critical for protecting ecosystems, climate change studies and ... -
Cooperative Autonomous Vehicle Speed Optimization near Signalized Intersections
(University of Waterloo, 2018-12-12)Road congestion in urban environments, especially near signalized intersections, has been a major cause of significant fuel and time waste. Various solutions have been proposed to solve the problem of increasing idling ... -
Cooperative Based Software Clustering on Dependency Graphs
(University of Waterloo, 2014-06-20)The organization of software systems into subsystems is usually based on the constructs of packages or modules and has a major impact on the maintainability of the software. However, during software evolution, the ... -
Cooperative Clustering Model and Its Applications
(University of Waterloo, 2008-09-24)Data clustering plays an important role in many disciplines, including data mining, machine learning, bioinformatics, pattern recognition, and other fields, where there is a need to learn the inherent grouping structure ... -
Cooperative Communication over Underwater Acoustic Channels
(University of Waterloo, 2013-06-18)As diverse and data-heavy underwater applications emerge, demanding requirements are further imposed on underwater wireless communication systems. Future underwater wireless communication networks might consist of both ... -
