Communication and Round Balanced Oblivious FSM Evaluation
Privacy is a major issue in the age of the Internet. Many advances are being made in Cryptography regarding performing computations over private data, both in homomorphic encryption, multi-party computation, and applications ... -
A Sequence Based Approach for Predicting Clinical Events
The data associated to each patient increases almost linearly as the patient flows through the continuum of care. Analysis of the data collected during a patient’s admission to the hospital reveals that it grows vertically ... -
Scalable Propagation Algorithms for Node Labeling in Bipartite Graphs
Bipartite graphs are graphs whose vertices can be partitioned into 2 different independent sets. Many interesting machine learning problems either present themselves naturally as problems of node ... -
Predictive Analytics and Decision Support for Heart Failure patients
In the last few years, legislations such as the Patient Protection and A ordable Care Act, also known as Obamacare, have emphasised the need for improving the quality of health care. Part of the programs introduced by this ... -
Classifying Child Maltreatment by Brain Imaging Data
Childhood maltreatment is a condition that leads to the development of behavioral issues and affect brain structure and functionality. Recent neuroimaging studies provide connection between deficits in brain volume, gray ... -
Gene Network Inference using Machine Learning and Graph Algorithms on Big Biomedical Data
Gene networks capture the interactions between different biological entities. These gene networks have many applications in modern day biology. In particular, gene networks can help to shed light on the underlying mechanisms ... -
Application of Machine Learning Techniques to Acute Myeloid Leukemia
This thesis is inspired by the position paper ”Predictive, personalized, preventive, par- ticipatory (P4) cancer medicine” [1]. The basic concept of P4 medicine was “The right patient with the right drug at the right dose ... -
An Evaluation of Complex Adaptive Evolvable System Simulation
Building models has been a human activity for centuries. Through the ages man has discovered patterns in how objects function together in the exchange of information, materials, and energy. We know these groups of objects ... -
Prediction and Privacy in Healthcare Analytics
In the past decade, the United States federal government has made improving the healthcare system a major focus with legislation such as the Patient Protection and Affordable Care Act and the financial incentives for ... -
Discrete Gaussian Sampling for Low-Power Devices
Sampling from the discrete Gaussian probability distribution is used in lattice-based cryptosystems. A need for faster and memory-efficient samplers has become a necessity for improving the performance of such cryptosystems. ... -
Energy-aware Workflow Scheduling and Fuzzy Logic Based Capacity Provisioning in Cloud Environment
The increasing need of large-scale data centers has brought new challenges to the development of energy-efficiency techniques. Although many optimization techniques have been proposed, most of them neglect the characteristics ... -
Selecting Robust Strategies in RTS Games via Concurrent Plan Augmentation
The multifaceted complexity of real-time strategy (RTS) games requires AI systems to break down policy computation into smaller subproblems such as strategic planning, tactical planning, and reactive control. To further ... -
Intervention Recommendations to Minimize the 30-Day Risk-of-Readmission for Heart Failure
In this thesis, we investigate the problem of designing personalized intervention strategies to minimize 30-day readmission risk for heart failure (HF) patients. In particular, we propose a novel framework that recommends ... -
Distributed Diverging Topic Models: A Novel Algorithm for Large Scale Topic Modeling in Spark
In their 2001 work Latent Dirichlet Allocation, Blei, Ng, and Jordan proposed the generative model of the same name that has since become the basis for most research in the field of topic modeling. The model overcame many ... -
Inferring Big 5 Personality from Online Social Networks
Online social networks are very popular with millions of people creating online profiles and sharing personal information including their interests, activities, likes/dislikes and thoughts with their friends and family. ... -
Predicting Risk of Re-hospitalization for Congestive Heart Failure Patients
(2013-04-17)Congestive Heart Failure (CHF) is one of the leading causes of hospitalization, and studies show that many of these admissions are readmissions. Identifying patients who are at a greater risk of hospitalization, can guide ... -
Adaptive Probabilistic Topic Models for Social Networks
(2012-09-13)Online social networks such as Twitter, LinkedIn, and Facebook generate tremendous amount of text and social interaction data. On one hand, the increasing amount of available information has motivated computational research ... -
SocialLDA:Scalable Topic Modeling in Social Networks
(2012-08-10)Topical categorization of blogs, documents or other objects that can be tagged with text, improves the experience for end users. Latent Dirichlet allocation (LDA) is a well studied algorithm that discovers latent topics ...
