A New Measure For Clustering Model Selection
(University of Waterloo, 2008-05-20)A new method for determining the number of k-means clusters in a given data set is presented. The algorithm is developed from a theoretical perspective and then its implementation is examined and compared to existing solutions. -
New Methods for Improving Accuracy in Three Distinct Predictive Modeling Problems
(University of Waterloo, 2018-08-22)People are often interested in predicting a new or future observation. In clinical prediction, the uptake of Electronic Health Records (EHRs) has generated massive health datasets that are big in volume and diverse in ... -
New methods for Quantum Compiling
(University of Waterloo, 2014-04-30)The efficiency of compiling high-level quantum algorithms into instruction sets native to quantum computers defines the moment in the future when we will be able to solve interesting and important problems on quantum ... -
A New Optimality Measure for Distance Dominating Sets
(University of Waterloo, 2006)We study the problem of finding the smallest power of an input graph that has <em>k</em> disjoint dominating sets, where the <em>i</em>th power of an input graph <em>G</em> is constructed by adding edges between pairs ... -
A new perspective on loss to follow-up in failure time and life history studies
(Wiley, 2019-07-24)A framework is proposed for the joint modeling of life history and loss to follow-up (LTF) processes in cohort studies. This framework provides a basis for discussing independence conditions for LTF and censoring and ... -
Niceness assumptions for Learning Algorithms
(University of Waterloo, 2014-08-01)Various machine learning algorithms like Neural Networks, Linear Regression, Feature Learning etc. are being employed successfully in a wide variety of applications like computer vision, speech recognition, bioinformatics ... -
Nine Challenges In Incorporating The Dynamics Of Behaviour In Infectious Diseases Models
(Elsevier, 2015-03-01)Traditionally, the spread of infectious diseases in human populations has been modelled with static parameters. These parameters, however, can change when individuals change their behaviour. If these changes are themselves ... -
No Zombie Types: Liveness-Based Justification For Monotonic Gradual Types
(University of Waterloo, 2021-08-24)Gradual type systems with the monotonic dynamic semantics, such as HiggsCheck implementing SafeTypeScript, are able to achieve decent performance, making them a viable option for JavaScript programmers seeking run-time-checkable ... -
NOCH: A framework for biologically plausible models of neural motor control
(University of Waterloo, 2010-01-20)This thesis examines the neurobiological components of the motor control system and relates it to current control theory in order to develop a novel framework for models of motor control in the brain. The presented framework ... -
Node-Weighted Prize Collecting Steiner Tree and Applications
(University of Waterloo, 2013-05-23)The Steiner Tree problem has appeared in the Karp's list of the first 21 NP-hard problems and is well known as one of the most fundamental problems in Network Design area. We study the Node-Weighted version of the Prize ... -
Noisy Embezzlement of Entanglement and Applications to Entanglement Dilution
(University of Waterloo, 2019-05-23)In this thesis we present the concept of embezzlement of entanglement, its properties, efficiency, possible generalizations and propose the linear programming characterization of this phenomenon. Then, we focus on the noisy ... -
Noisy Interactive Quantum Communication
(University of Waterloo, 2020-08-25)We consider the problem of implementing two-party interactive quantum communication over noisy channels, a necessary endeavor if we wish to fully reap quantum advantages for communication. For an arbitrary protocol with n ... -
Non-Adaptive Matroid Prophet Inequalities
(University of Waterloo, 2023-05-04)We consider the problem of matroid prophet inequalities. This problem has been ex- tensively studied in case of adaptive prices, with [KW12] obtaining a tight 2-competitive mechanism for all the matroids. However, the ... -
Non-compact groups, tensor operators and applications to quantum gravity
(University of Waterloo, 2016-09-23)This work focuses on non-compact groups and their applications to quantum gravity, mainly through the use of tensor operators. Non-compact groups appear naturally if the space-time is of Lorentzian signature, but can also ... -
Non-Constructivity in Security Proofs
(University of Waterloo, 2018-09-10)In the field of cryptography, one generally obtains assurances for the security of a cryptographic protocol by giving a reductionist security proof, which is comprised of a reduction from breaking a mathematical problem ... -
The non-injective hidden shift problem
(University of Waterloo, 2012-01-19)In this work, we mostly concentrate on the hidden shift problem for non-injective functions. It is worthwhile to know that the query complexity of the non-injective hidden shift problem is exponential in the worst case by ... -
A Non-Intersecting R-Tree
(University of Waterloo, 2021-05-12)Indexes for multidimensional data based on the R-Tree are popularly used by databases for a wide range of applications. Such index trees support point and range queries but are costly to construct over datasets of millions ... -
Non-Intrusive Computing
(University of Waterloo, 2008-12-17)Pervasive computing is an important trend today. It concerns devices and services in a smart space that interact with users in a simple, natural, and harmonious way. Many problems in this domain have been studied from ... -
