Algorithms for Analyzing Spatio-Temporal Data
(2018)
In today's age, huge data sets are becoming ubiquitous. In addition to their size,
most of these data sets are often noisy, have outliers, and are incomplete. Hence,
analyzing such data is challenging. We look at applying ...
Applying Differential Privacy with Sparse Vector Technique
(2018)
In today's fast-paced developing digital world, a wide range of services such as web
services, social networks, and mobile devices collect a large amount of personal data
from their users. Although sharing and mining large-scale ...
Managing Shared Resources in the Data Center Era
(2018)
To improve efficiency and amortize cost over more computation, resource sharing has
become vital in high performance computing systems. In such systems, the conventional
wisdom assumes that users have to share, regardless ...
Eliciting and Aggregating Information for Better Decision Making
(2018)
In this thesis, we consider two classes of problems where algorithms are increasingly
used to make, or assist in making, a wide range of decisions. The first class of problems
we consider is the allocation of jointly owned ...
Policy Driven Data Sharing with Provable Privacy Guarantees
(2018)
Companies such as Google or Facebook collect a substantial amount of data about their
users to provide useful services. The release of these datasets for general use can
enable numerous innovative applications and scientific ...
Assuring Data Authenticity While Preserving User Choice in Mobile Sensing
(2018)
As more services have come to rely on sensor data such as photos and audio collected
by mobile phone users, verifying the authenticity of this data has become critical
for service correctness. At the same time, contributors ...
Getting More Out of the Existing Internet Infrastructure To Improve User Experiences
(2018)
Providing a satisfactory quality of experience (QoE) to Internet users is crucial
for content and service providers. When users get bad QoE from an application, such
as the videos they are watching on a streaming provider ...
Human Activity Analysis
(2018)
Video cameras have become increasingly prevalent, with higher resolution and frame-rates.
Humans are often the focus of these videos, making human motion analysis an important
field. This thesis explores the level of detail ...
Symmetric completion of Deformable Registration via Bi-residual Inversion
(2018)
Deformable image registration is fundamental and critical to both diagnostics and
therapeutics in precision and personalized medicine. Existing software packages for
deformable registrations either provide only a forward ...
Parallel Memory Permissions and Their Applications
(2018)
A process can voluntarily set memory protections to different portions of its address
space. As threads in a process share the same address space, they are equally bound
to its protections. In this dissertation, we explore ...
