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" ...
Algorithm-Architecture Co-Design for Dense Linear Algebra Computations
(2018-08-13)
Achieving high computation efficiency, in terms of Cycles per Instruction (CPI), for high-performance computing kernels is an interesting and challenging research area. Dense Linear Algebra (DLA) computation is a representative ...
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 ...
Sparsity Motivated Auditory Wavelet Representation and Blind Deconvolution
(2018-08-29)
In many scenarios, events such as singularities and transients that carry important information about a signal undergo spreading during acquisition or transmission and it is important to localize the events. For example, ...
Sparse Bayesian Learning For Joint Channel Estimation Data Detection In OFDM Systems
(2018-08-30)
Bayesian approaches for sparse signal recovery have enjoyed a long-standing history in signal processing and machine learning literature. Among the Bayesian techniques, the expectation maximization based Sparse Bayesian ...
Incentive Strategies and Algorithms for Networks, Crowds and Markets
(2018-08-02)
This work is motivated by several modern applications involving social networks, crowds, and markets. Our work focuses on the theme of designing effective incentive strategies for these applications. Viral marketing is ...
Design, Analysis and Development of Sensor Coil for Fiber Optics Gyroscope
(2018-07-30)
Interferometer Fiber Optic Gyroscope (IFOG) has established as critical sensor for advance navigation systems. Sensor coil is known to be heart of IFOG. The bias drift and scale factor performance of IFOG depend on the ...
Trajectory-based Descriptors for Action Recognition in Real-world Videos
(2018-07-30)
This thesis explores motion trajectory-based approaches to recognize human actions in
real-world, unconstrained videos. Recognizing actions is an important task in applications
such as video retrieval, surveillance, ...
Effective Characterization of Sequence Data through Frequent Episodes
(2018-08-14)
Pattern discovery is an important area of data mining referring to a class of techniques designed for the extraction of interesting patterns from the data. A pattern is some kind of a local structure that captures correlations ...
Modeling and Analysis of Grid Connected Variable Speed Wind Generators
(2018-08-13)
The growing demand for power and increased environmental concerns gave an impetus to the growth of clean and renewable energy sources like wind, solar etc. There is a remarkable increase in the penetration of wind energy ...
