Retinotopic Preservation in Deep Belief Network Visual Learning
(University of Waterloo, 2011-04-29)One of the foremost characteristics of the mammalian visual system is the retinotopic mapping observed in the low-level visual processing centres; the spatial pattern of activation in the lateral geniculate nucleus and ... -
Retrieving Supporting Evidence for Generative Question Answering
(University of Waterloo, 2023-12-18)Current large language models (LLMs) can exhibit near-human levels of performance on many natural language-based tasks, including open-domain question answering. Unfortunately, at this time, they also convincingly hallucinate ... -
A Review And Analysis Of The Sustainability And Equity Of Social Security Adjustment Mechanisms
(University of Waterloo, 2008-10-24)This thesis examines stabilizing mechanisms in social security retirement systems (“SSRS”), especially those purporting to be automatic balancing mechanisms (“ABM”). It develops a consistent approach to identifying whether ... -
Revising Ecological Assumptions About Human Papillomavirus Interactions And Type Replacement
(Elsevier, 2014-06-07)The controversy over whether vaccine-targeted HPV types will be replaced by other oncogenic, non-vaccine-targeted types remains unresolved. This is in part because little is known about the ecology of HPV types. Patient ... -
Revisiting Password Rules: Facilitating Human Management of Passwords
(IEEE, 2016-06)Password rules were established in the context of past security concerns. Recent work in computer security challenges the conventional wisdom of expert password advice, such as change your passwords often, do not reuse ... -
Revisiting the security model for aggregate signature schemes
(University of Waterloo, 2014-05-26)Aggregate signature schemes combine the digital signatures of multiple users on different messages into one single signature. The Boneh-Gentry-Lynn-Shacham (BGLS) aggregate signature scheme is one such scheme, based on ... -
Rhyme, Rhythm, and Rhubarb: Using Probabilistic Methods to Analyze Hip Hop, Poetry, and Misheard Lyrics
(University of Waterloo, 2010-08-30)While text Information Retrieval applications often focus on extracting semantic features to identify the topic of a document, and Music Information Research tends to deal with melodic, timbral or meta-tagged data of songs, ... -
Rigidity of near-optimal superdense coding protocols
(University of Waterloo, 2023-09-19)Rigidity in quantum information theory refers to the stringent constraints underlying optimal or near-optimal performance in certain quantum tasks. This property plays a crucial role in verifying untrusted quantum devices ... -
Risk Allocation in Hybrid Pension Plans
(University of Waterloo, 2019-09-18)Three different hybrid designs are considered in this thesis. Chapter 1 studies the risk management of Cash Balance (CB) pension plans, which are the most popular hybrid plans in the U.S. We show that the simple delta and ... -
Risk Analysis: Measures of concordance, their compatibility and capital allocation
(University of Waterloo, 2020-08-20)This thesis addresses various topics in the field of probability theory and statistics with applications in quantitative risk management. The first topic concerns matrix compatibility and attainability problems for ... -
Risk Management with Basis Risk
(University of Waterloo, 2018-06-19)Basis risk occurs naturally in a variety of financial and actuarial applications, and it introduces additional complexity to the risk management problems. Current literature on quantifying and managing basis risk is still ... -
Risk Management with Non-Convex and Non-Monotone Preferences
(University of Waterloo, 2019-06-24)This thesis studies two types of problems, the theory of risk functionals and the risk sharing problem. We put a special focus on a class of non-monotone law-invariant risk functionals, called the signed Choquet integrals. The ... -
Risk Measure Approaches to Partial Hedging and Reinsurance
(University of Waterloo, 2014-01-22)Hedging has been one of the most important topics in finance. How to effectively hedge the exposed risk draws significant interest from both academicians and practitioners. In a complete financial market, every ... -
Risk Measurement under Dependence Structure Ambiguity
(University of Waterloo, 2022-01-27)In this thesis, we work on a generalization of the entropy regularized optimal transport problem, with the objective function being (spectral) risk measures. We accomplish three goals: to present the corresponding dual ... -
Risk Measures and Capital Allocation Principles for Risk Management
(University of Waterloo, 2016-09-21)Risk measures (or premium principles) and capital allocation principles play a signi cant role in risk management. Regulators and companies in the nancial markets usually adopt an appropriate risk measure, for example, ... -
Risk Measures and Optimal Reinsurance
(University of Waterloo, 2015-08-21)In this thesis, we study the optimal reinsurance design problem and extend the classical model in three different directions: (1) In the first framework, we add the additional assumption that the reinsurer can default ... -
Risk Measures of Stop-loss and Limited Loss Random Variables under Model Uncertainty with Applications in Insurance
(University of Waterloo, 2023-09-07)In this thesis, our focus is on the optimization of reinsurance design, accounting for the influence of model uncertainty. The following chapters outline our approach: In Chapter 2, we identify the worst-case distributions ... -
Risk Modelling in Shariah Compliant Investment and Insurance Products
(University of Waterloo, 2021-09-28)The main objective of this study is to develop a risk model for Shariah (Islamic) compliant investment and insurance. Islamic finance is a part of Socially Responsible Investment (SRI) that incorporates religious ethics. ... -
Risk Sharing and Risk Aggregation via Risk Measures
(University of Waterloo, 2017-04-21)Risk measures have been extensively studied in actuarial science in the guise of premium calculation principles for more than 40 years, and recently, they have been the standard tool for financial institutions in both ... -
RitHM: A Modular Software Framework for Runtime Monitoring Supporting Complete and Lossy Traces
(University of Waterloo, 2015-10-01)Runtime verification (RV) is an effective and automated method for specification based offline testing as well as online monitoring of complex real-world systems. Firstly, a software framework for RV needs to exhibit certain ...
