Applications of Stochastic Gradient Descent to Nonnegative Matrix Factorization
(University of Waterloo, 2019-07-15)We consider the application of stochastic gradient descent (SGD) to the nonnegative matrix factorization (NMF) problem and the unconstrained low-rank matrix factorization problem. While the literature on the SGD algorithm ... -
Applications of stochastic modeling and data analytics techniques in healthcare decision making
(University of Waterloo, 2017-12-19)We present approaches utilizing aspects of data analytics and stochastic modeling techniques and applied to various areas in healthcare. In general, the thesis has composed of three major components. Firtsly, we propose ... -
Applications of the minimal modelprogram in arithmetic dynamics
(University of Waterloo, 2021-09-07)Let F be a surjective endomorphism of a normal projective variety X defined over a number field. The dynamics of F may be studied through the dynamics of the linear action of an associated linear pull-back action on divisors. ... -
Applications of the Quantum Kernel Method on a Superconducting Quantum Processor
(University of Waterloo, 2020-05-29)The widespread benefits of classical machine learning along with promised speedups by quantum algorithms over their best performing classical counterparts have motivated development of quantum machine learning algorithms ... -
Applications of the Wormlike Chain Model in Polymer Physics: Self-consistent Field Theory
(University of Waterloo, 2013-04-30)The self-consistent field theory (SCFT) has reveived a great success in prediction of the physical properties of a variety of polymeric systems in the recent two decades. However, the traditional SCFT is based on the ... -
Applied Hilbert's Nullstellensatz for Combinatorial Problems
(University of Waterloo, 2016-09-23)Various feasibility problems in Combinatorial Optimization can be stated using systems of polynomial equations. Determining the existence of a \textit{stable set} of a given size, finding the \textit{chromatic number} of ... -
Applied soybean and maize residue contributions to soil organic matter in a temperate soybean/maize intercropping system
(University of Waterloo, 2013-02-22)Intercropping, defined as two or more crops grown on the same land area at the same time, is a sustainable alternative to sole crops. Intercropping has been associated with multiple benefits, such as increased nutrient and ... -
Applying a Systems Thinking Approach to Health Care for Women & Children in the Flood Plains of Western Zambia
(University of Waterloo, 2022-09-16)At least half of the world’s population are reportedly unable to obtain essential health services with significant gaps being noted in sub–Saharan Africa and Southern Asia. Access to health services incorporates physical ... -
Applying Fair Reward Divisions to Collaborative Work
(University of Waterloo, 2019-07-18)Collaborative crowdsourcing tasks allow workers to solve more difficult problems than they could alone, but motivating workers in these tasks is complex. In this thesis, we study how to use payments to motivate groups of ... -
Applying Fully Homomorphic Encryption: Practices and Problems
(University of Waterloo, 2021-09-24)Fully homomorphic encryption (FHE) has been regarded as the "holy grail" of cryptography for its versatility as a cryptographic primitive and wide range of potential applications. Since Gentry published the first theoretically ... -
Applying the Allostatic Load Model to Investigate the Biological Embedding of Psychosocial Stress in Firefighters
(University of Waterloo, 2022-08-30)Overview Psychosocial factors are recognised as a significant source of stress in the workplace, and long-term exposure to such stressors may increase chronic disease risk through physiological wear and tear quantified ... -
Applying the Integrated Solid Waste Management Framework to the Waste Collection System in Aguascalientes, AGS, Mexico
(University of Waterloo, 2011-06-16)The design of a waste collection system affects public health, the extent of participation in the system by residents, the recovery of resources from waste, and the cost of collection. Many developing countries use communal ... -
Approach Motivation Gives Rise to Meaning in Life
(University of Waterloo, 2018-09-18)Coherence, purpose, and significance have emerged as the three contributors to meaning in life. Current theories have primarily emphasized coherence as key to meaning, neglecting purpose and significance. A theoretical ... -
Approach to Evaluating Clustering Using Classification Labelled Data
(University of Waterloo, 2011-01-17)Cluster analysis has been identified as a core task in data mining for which many different algorithms have been proposed. The diversity, on one hand, provides us a wide collection of tools. On the other hand, the profusion ... -
An Approach to Quantifying Uncertainty in Estimates of Intensity Duration Frequency (IDF) Curves
(University of Waterloo, 2013-08-22)Generally urban drainage systems are built to protect urban property and control runoff. Moreover, these systems collect the runoff for storage purposes to serve society through sufficient water supply to meet the needs ... -
