Displaying believable emotional reactions in virtual characters is required in applications ranging from virtual-reality trainers to video games. Manual scripting is the most frequently used method and enables an arbitrarily high fidelity of the emotions displayed. However, scripting is labor...

Transceiver duty-cycling (DC) is a popular technique to conserve energy in a wireless sensor network (WSN). In this thesis, our overall objective is to study the performance of a DC WSN. Namely, we consider the performance of a DC WSN from the point of throughput, as well as energy consumption,...

Much of the focus on finding good representations in reinforcement learning has been on learning complex non-linear predictors of value. Methods like policy gradient, that do not learn a value function and instead directly represent policy, often need fewer parameters to learn good policies....

In this thesis, we consider two closely related clustering problems, Min Sum k-Clustering (MSkC) and Balanced k-Median (BkM). In Min Sum k-clustering, one is given a graph and a parameter k, and has to partition the vertices in the graph into k clusters to minimize the sum of pairwise distances...

We study the Single-Minded Pricing, Unique Coverage, and Uniform-Budget Single-Minded Pricing problems on graphs and on geometric objects. In Single Minded Pricing, we are given a set of items and a collection of subsets of the items, called demands. For each demand, we are also given a budget....

How to evaluate the performance of an algorithm is a very important subject in computer science, for understanding its applicability, for understanding the problem which it is applied to, and for the development of new ideas that help to improve the existing algorithms. There are two main...

An atlas is an anatomical representation containing all brain structures well identified in a stereotaxic space from a single subject or a population. Atlases provide information about the organization and localization of the different brain tissues. One may take advantage of this well-organized...

Information networks that describe the relationship between individuals are called social networks and are usually modeled by a graph structure. Social network analysis is the study of these information networks which leads to uncovering patterns of interaction among the entities. Community...

Believable, realistic video game character behaviour continues to lag behind the improvements in graphics, stories and game play in video games. In this dissertation we focus on the use of two techniques, emotional gaits and emotional incidents, as a way to add easily identifiable, non-verbal,...

Determining the viewpoint (pose) of rigid objects in images is a classic vision problem with applications to robotic grasping, autonomous navigation, augmented reality, semantic SLAM and scene understanding in general. While most existing work is characterized by phrases such as "coarse pose...
