Actuarial Inference and Applications of Hidden Markov Models
(University of Waterloo, 2011-08-17)Hidden Markov models have become a popular tool for modeling long-term investment guarantees. Many different variations of hidden Markov models have been proposed over the past decades for modeling indexes such as the S&P ... -
Actuarial Ratemaking in Agricultural Insurance
(University of Waterloo, 2015-08-06)A scientific agricultural (re)insurance pricing approach is essential for maintaining sustainable and viable risk management solutions for different stakeholders including farmers, governments, insurers, and reinsurers. ... -
Acyclic Colouring of Graphs on Surfaces
(University of Waterloo, 2018-09-04)An acyclic k-colouring of a graph G is a proper k-colouring of G with no bichromatic cycles. In 1979, Borodin proved that planar graphs are acyclically 5-colourable, an analog of the Four Colour Theorem. Kawarabayashi and ... -
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 CPU Allocation for Resource Isolation and Work Conservation
(University of Waterloo, 2020-07-06)Consolidating multiple workloads on the same physical machine is an effective measure for utilizing resources efficiently and reducing costs. The main objective is to execute multiple demanding workloads using no more than ... -
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 Data Storage and Placement in Distributed Database Systems
(University of Waterloo, 2022-09-01)Distributed database systems are widely used to provide scalable storage, update and query facilities for application data. Distributed databases primarily use data replication and data partitioning to spread load across ... -
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 Human-Chatbot Interactions: Contextual Factors, Variability Design and Levels of Automation
(University of Waterloo, 2023-12-05)The landscape of software development is undergoing a significant transformation characterized by various factors. A notable shift is the surging demand for software developers, driven by industries' increasing reliance ... -
Adaptive policies and drawdown problems in insurance risk models
(University of Waterloo, 2015-08-31)Ruin theory studies an insurer's solvency risk, and to quantify such a risk, a stochastic process is used to model the insurer's surplus process. In fact, research on ruin theory dates back to the pioneer works of Lundberg ... -
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 ... -
Adaptive User Authentication on Mobile Devices
(University of Waterloo, 2022-07-19)Modern mobile devices allow users to access various applications and services anywhere. However, high mobility also exposes mobile devices to device loss, unauthorized access, and many other risks. Existing studies have ... -
An adaptive variational finite difference framework for efficient symmetric octree viscosity
(ACM, 2019-07)While pressure forces are often the bottleneck in (near-)inviscid fluid simulations, viscosity can impose orders of magnitude greater computational costs at lower Reynolds numbers. We propose an implicit octree finite ... -
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 ... -
Addressing the Issues of Coalitions and Collusion in Multiagent Systems
(University of Waterloo, 2013-05-22)In the field of multiagent systems, trust and reputation systems are intended to assist agents in finding trustworthy partners with whom to interact. Earlier work of ours identified in theory a number of security ...
