P3 : An Effective Technique for Partitioned Path Profiling
Acyclic path profile is an abstraction of dynamic control flow paths of procedures and
has been found to be useful in a wide spectrum of activities. Unfortunately, the runtime
overhead of obtaining such a profile can be ...
Decision Making under Uncertainty : Reinforcement Learning Algorithms and Applications in Cloud Computing, Crowdsourcing and Predictive Analytics
In this thesis, we study both theoretical and practical aspects of decision making, with a focus on reinforcement learning based methods. Reinforcement learning (RL) is a form of semi-supervised learning in which the agent ...
Program Analyses to Support Memory-saving Refactorings in Java Programs
Software commonly consumes unexpectedly high amounts of memory, frequently due to programming idioms that are used to make software more reliable, maintainable and understandable. In the case of modern object-oriented ...
Falcon : A Graph Manipulation Language for Distributed Heterogeneous Systems
(2018-08-20)
Graphs model relationships across real-world entities in web graphs, social network graphs, and road network graphs. Graph algorithms analyze and transform a graph to discover graph properties or to apply a computation. ...
Design and Analysis of Consistent Algorithms for Multiclass Learning Problems
(2018-08-14)
We consider the broad framework of supervised learning, where one gets examples of objects together with some labels (such as tissue samples labeled as cancerous or non-cancerous, or images of handwritten digits labeled ...
Feature Selection under Multicollinearity & Causal Inference on Time Series
(2018-08-20)
In this work, we study and extend algorithms for Sparse Regression and Causal Inference problems. Both the problems are fundamental in the area of Data Science.
The goal of regression problem is to nd out the \best" ...
A Fine-Grained Dynamic Information Flow Analysis for Android Apps
(2018-08-20)
Android has been steadily gaining popularity ever since its launch in 2008. One of the major factors for this is the easy availability of a large variety of apps. They range from simple apps such as calculator apps to apps ...
New Models and Methods for Formation and Analysis of Social Networks
Social networks are an inseparable part of human lives, and play a major role in a wide range of activities in our day-to-day as well as long-term lives. The rapid growth of online social networks has enabled people to ...
Computing Contour Tress for 2D Piecewise Polynomial Functions
Contour trees are extensively used in scalar field analysis. The contour tree is a data structure that tracks the evolution of level set topology in a scalar field. Scalar fields are typically available as samples at ...
Data Structures and Algorithms to Analyze Concurrency in Android Applications
Android is a popular mobile operating system, providing a rich ecosystem for the development of applications which run on the Android platform. Entities such as the device user, network and sensors interact continuously ...
