Cost-Sensitive Boosting for Classification of Imbalanced Data
(University of Waterloo, 2007-05-11)The classification of data with imbalanced class distributions has posed a significant drawback in the performance attainable by most well-developed classification systems, which assume relatively balanced class ... -
Costly Actions, External Incentives and Prediction Markets
(University of Waterloo, 2017-08-25)Consider a prediction market of multiple rounds with a security contingent on a certain event whose final outcome is decided by the agents who also trade in the market. One such prediction market is one in which two agents, ... -
The costs of bonding: negotiating personal information disclosure among Millennials and Boomers on Facebook
(University of Waterloo, 2013-09-03)Since early 2010, Facebook.com, the world’s most popular social network site (SNS), has come under a storm of media criticism over the commercial use of its users’ personal information. Yet even as more became known about ... -
Could The Human Papillomavirus Vaccines Drive Virulence Evolution?
(Royal Society, The, 2015-01-07)The human papillomavirus (HPV) vaccines hold great promise for preventing several cancers caused by HPV infections. Yet little attention has been given to whether HPV could respond evolutionarily to the new selection ... -
Counterculture Plan for the Creative City: A Critique of Patterns of Flexibility and Fixity in Toronto's Cultural Renaissance
(University of Waterloo, 2021-09-07)Between the years 2000 and 2010, the City of Toronto experienced an unprecedented spike in cultural construction. This building boom, ushered in by Toronto’s “Culture Plan for the Creative City” and dubbed “Toronto’s ... -
A Counterexample to a Conjecture About Triangle-Free Induced Subgraphs of Graphs with Large Chromatic Number
(Elsevier ScienceDirect, 2023-01)We prove that for every n, there is a graph G with χ(G) ≥ n and ω(G) ≤ 3 such that every induced subgraph H of G with ω(H) ≤ 2 satisfies χ(H) ≤ 4.This disproves a well-known conjecture. Our construction is a digraph with ... -
The Counterpublic of Union Station; An Alternative Future of Toronto's Transit Terminal
(University of Waterloo, 2017-09-27)Though Toronto’s public spaces were conceived as spaces of discourse engendering democratic participation, today we witness their degradation into platforms of consumption. Contemporary Capitalist forces engulf the city’s ... -
Counting and Mining Research Data with Unix
(The Editorial Board of the Programming Historian, 2014-09-20)This lesson will look at how research data, when organised in a clear and predictable manner, can be counted and mined using the Unix shell. The lesson builds on the lessons “Preserving Your Research Data: Documenting and ... -
Counting Bases
(University of Waterloo, 2004)A theorem of Edmonds characterizes when a pair of matroids has a common basis. Enumerating the common bases of a pair of matroid is a much harder problem, and includes the #P-complete problem of counting the number of ... -
Counting Carbon: Evaluating the Quality and Environmental Impacts of Design Through Product Prototyping
(University of Waterloo, 2022-05-19)Industrialisation has brought numerous advancements to the architecture and design fields, many of which have allowed humanity to produce more efficiently, using less energy and human labour. Simultaneously, mass production ... -
Counting Flimsy Numbers via Formal Language Theory
(University of Waterloo, 2021-02-02)Let s_2(n) be the sum of the digits of n when expressed in base 2. For integers n and k, Stolarsky defined n to be k-flimsy if s_2(kn) < s_2(n). In this paper, we generalize the definition of k-flimsy numbers to all bases ... -
Counting Pentagons in Triangle-free Binary Matroids
(University of Waterloo, 2020-07-30)A rank-n binary matroid is a spanning subset E of F₂ⁿ\{0}, a triangle is a set of three elements from E which sum to zero, and the density of a rank-n binary matroid is |E|/2ⁿ. We begin by giving a new exposition of a ... -
Counting points of bounded height on del Pezzo surfaces
(University of Waterloo, 2006)del Pezzo surfaces are isomorphic to either P<sup>1</sup> x P<sup>1</sup> or P<sup>2</sup> blown up <i>a</i> times, where <i>a</i> ranges from 0 to 8. We will look at lines on del Pezzo surfaces isomorphic to P<sup>2</sup> ... -
Counting What Counts: When and How Performance Indicators Mislead
(University of Waterloo, 2019-09-18)People often rely on performance indicators for feedback on broad personal and organizational goals, e.g., using body weight to assess health and, in academia, using publication count to assess scientific contribution. ... -
Counting, Adding, and Regular Languages
(University of Waterloo, 2018-12-17)In this thesis we consider two mostly disjoint topics in formal language theory that both involve the study and use of regular languages. The first topic lies in the intersection of automata theory and additive number ... -
Country Food Consumption Notices: Assessing Awareness and Preferences of Health and Risk Communication Messages in the Sahtú Region of the Northwest Territories
(University of Waterloo, 2018-10-22)Background: Country food consumption by Indigenous peoples is associated with improved nutrition, food security, and lower rates of chronic diseases (Kuhnlein, Burlingame, & Erasmus, 2013); however, these foods can also ... -
Coupled chemically-assisted filtration (CCAF) approaches for increasing filter resilience and performance during drinking water treatment
(University of Waterloo, 2021-05-11)The paramount objective of drinking water treatment is the prevention of acute waterborne disease. Filtration remains a critical barrier for ensuring that Cryptosporidium spp. and Giardia are removed during drinking water ... -
