Causal Sensitivity Analysis for Decision Trees
(University of Waterloo, 2015-01-15)Ventilator assignments in the pediatric intensive care unit (PICU) are made by medical experts; however, for some patients the relationship between ventilator assignment and patient health status is not well understood. ... -
CBKR+: A Conceptual Framework for Improving Corpus Based Knowledge Representation
(University of Waterloo, 2006)In Corpus Based Knowledge Representation [CBKR], limited association capability, that is, no criteria in place to extract substantial associations in the corpus, and lack of support for hypothesis testing and prediction ... -
Cell Path Reconstruction Using 3D Digital Inpainting
(University of Waterloo, 2013-08-06)Digital inpainting is the reconstruction of a missing or damaged region in a digital image. Intensity values in the missing region are approximated using information near the boundary of the region. Some applications include ... -
A cell-centred finite volume method for the Poisson problem on non-graded quadtrees with second order accurate gradients
(Elsevier, 2017-02-15)This paper introduces a two-dimensional cell-centred finite volume discretization of the Poisson problem on adaptive Cartesian quadtree grids which exhibits second order accuracy in both "the solution and its gradients, ... -
CGU: A common graph utility for DL Reasoning and Conjunctive Query Optimization
(University of Waterloo, 2005)We consider the overlap between reasoning involved in <em>conjunctive query optimization</em> (CQO) and in tableaux-based approaches to reasoning about subsumption in <em>description logics</em> (DLs). In both cases, an ... -
Characterizing Hardness in Parameterized Complexity
(University of Waterloo, 2007-05-18)Parameterized complexity theory relaxes the classical notion of tractability and allows to solve some classically hard problems in a reasonably efficient way. However, many problems of interest remain intractable in the ... -
Characterizing User Search Intent and Behavior for Click Analysis in Sponsored Search
(University of Waterloo, 2013-05-24)Interpreting user actions to better understand their needs provides an important tool for improving information access services. In the context of organic Web search, considerable effort has been made to model user behavior ... -
ClaferMPS: Modeling and Optimizing Automotive Electric/Electronic Architectures Using Domain-Specific Languages
(University of Waterloo, 2017-01-23)Modern automotive electric/electronic (E/E) architectures are growing to the point where architects can no longer manually predict the effects of their design decisions. Thus, in addition to applying an architecture reference ... -
Classification and Decision-Theoretic Framework for Detecting and Reporting Unseen Falls
(University of Waterloo, 2016-02-18)Detecting falls is critical for an activity recognition system to ensure the well being of an individual. However, falls occur rarely and infrequently, therefore sufficient data for them may not be available during training ... -
Classifying Code as Human Authored or GPT-4 Generated
(University of Waterloo, 2024-05-09)Artificial intelligence (AI) assistants such as GitHub Copilot and ChatGPT, built on large language models like GPT-4, are revolutionizing how programming tasks are performed, raising questions about whether generative AI ... -
CLBlood: A Cell-Based Light Interaction Model for Human Blood
(University of Waterloo, 2012-01-19)The development of predictive appearance models for organic tissues is a challenging task due to the inherent complexity of these materials. In this thesis, we closely examine the biophysical processes responsible for the ... -
Closing the Modelling Gap: Transfer Learning from a Low-Fidelity Simulator for Autonomous Driving
(University of Waterloo, 2020-01-24)The behaviour planning subsystem, which is responsible for high-level decision making and planning, is an important aspect of an autonomous driving system. There are advantages to using a learned behaviour planning system ... -
CLPush: Proactive Cache Transfers in NUMA Applications
(University of Waterloo, 2023-09-26)Modern Non-Uniform Memory Access (NUMA) systems support a thread count of as much as 128 threads to support high performance applications. These systems usually employ a scalable cache-coherent directory mechanism to ensure ... -
Clustering Dependencies over Relational Tables
(University of Waterloo, 2016-01-22)Integrity constraints have proven to be valuable in the database field. Not only can they help schema design (functional dependencies, FDs [1][2]), they can also be used in query optimization (ordering dependencies, ODs ... -
Clustering in the Presence of Noise
(University of Waterloo, 2013-08-26)Clustering, which is partitioning data into groups of similar objects, has a wide range of applications. In many cases unstructured data makes up a significant part of the input. Attempting to cluster such part of the data, ... -
Coding Strip: A Tool for Supporting Interplay within Abstraction Ladder for Computational Thinking
(University of Waterloo, 2022-05-20)As technologies advance and play an increasingly larger role in our lives, computational thinking---the ability to understand computing concepts and procedures and their role in the tools we use---has become an important ... -
A Collapsing Method for Efficient Recovery of Optimal Edges
(University of Waterloo, 2002)In this thesis we present a novel algorithm, <I>HyperCleaning*</I>, for effectively inferring phylogenetic trees. The method is based on the quartet method paradigm and is guaranteed to recover the best supported edges ... -
Combinatorial and Probabilistic Approaches to Motif Recognition
(University of Waterloo, 2010-11-10)Short substrings of genomic data that are responsible for biological processes, such as gene expression, are referred to as motifs. Motifs with the same function may not entirely match, due to mutation events at a few of ... -
Combinatorial Problems in Compiler Optimization
(University of Waterloo, 2013-04-22)Several important compiler optimizations such as instruction scheduling and register allocation are fundamentally hard and are usually solved using heuristics or approximate solutions. In contrast, this thesis examines ... -
