General Quadratic Risk Minimization: a Variational Approach
(University of Waterloo, 2016-07-05)
Mean-variance portfolio selection and mean-variance hedging are mainstream research topics in mathematical nance, which can be subsumed within the framework of a general problem of quadratic risk minimization. We study ...
A Socio-Psychological Approach to the Iterated Prisoner's Dilemma
(University of Waterloo, 2016-10-25)
Affect Control Theory (ACT), as a model of human interaction, attempts to capture a part of the human psyche that tends to go overlooked in the study of Artificial Intelligence: the role of emotion in decision making. It ...
Website Fingerprinting: Attacks and Defenses
(University of Waterloo, 2016-01-13)
Website fingerprinting attacks allow a local, passive eavesdropper to determine a client's web activity by leveraging features from her packet sequence. These attacks break the privacy expected by users of privacy technologies, ...
On The Density of Binary Matroids Without a Given Minor
(University of Waterloo, 2016-12-21)
This thesis is motivated by the following question: how many elements can a simple binary matroid with no $\PG(t,2)$-minor have? This is a natural analogue of questions asked about the density of graphs in minor-closed ...
Graph C*-algebras and the Abelian Core
(University of Waterloo, 2016-08-26)
We may associate to a C*-algebra to the directed graph E by associating edges to partial isometries and vertices to pairwise orthogonal Hilbert spaces which satisfy some additional conditions. Such graph algebras were first ...
Biologically inspired methods in speech recognition and synthesis: closing the loop
(University of Waterloo, 2016-02-18)
Current state-of-the-art approaches to computational speech recognition and synthesis are based on statistical analyses of extremely large data sets. It is currently unknown how these methods relate to the methods that ...
