Despite earlier evidence to the contrary, recent inquiries appear to reach a consensus that the poor
pay more for food. However, these studies utilize samples drawn on the basis of prior
knowledge of unfair pricing strategies, proximity of volunteer surveyors,…

In this thesis, we investigated a sequential decision making problem. We tested
different policies for online portfolio optimization: for a given number of assets and
a time horizon, the weights on assets are rebalanced at every time step according to

The antimicrobial effects of copper have been well established and may prove to be an effective means of reducing nosocomial or hospital-acquired infections. However, discussions surrounding the antimicrobial properties of copper-containing surfaces rarely address the effect of such materials on…

The goal of this project was two-fold: first, to improve the performance of machine learning
algorithms for the diagnosis of pediatric tuberculosis, and second, to use machine learning algorithms
to better understand the problem of diagnosis. We constructed and examined…

To investigate the influence of input from fellow group members in a constrained decision-making context, we develop four 2-armed bandit tasks in which subjects freely select one of two options (A or B) and are informed of the resulting reward…

This dissertation concerns itself with the effects of education and wealth on health in Africa. The first two chapters focus on the impact of adult education levels on the HIV epidemic in four sub-Saharan countries. The last chapter turns to…

The limitations common to linear imaging techniques were formalized succinctly by Ernst Abbe in 1873. In his theory, each Fourier component of a signal propagates independently from the source to the detector, and the corresponding feature can be detected only…

This paper discusses the motivation, design, implementation, and evaluation of a
new electronic beat sequencing system called HMM Beats. HMM Beats is inspired
by recent work in machine learning on user drum beat prediction. HMM Beats is
an interactive system…

We explore, in increasing complexity, various strategies for addressing the Multi-
Armed Bandit Problem in order to find the algorithm that maximizes the clickthrough
rate in the Exploration and Exploitation Challenge 3 competition. The data used
result from the actions…

The objective of this thesis project is to build a robot that can clearly demonstrate its
potential to solve standard jigsaw puzzles. This robot must be capable of picking up
and reorienting puzzle pieces to the precision required for completing…
