On the Complexity of Tipping in Super-Modular Games
(2014-05)
The problem of finding the minimum tipping set in a super modular game is known to be NP-hard. Here, I derive an approximation algorithm to find a small tipping set in such a game. In the special case of the uniform game, ...
Learning Relational Concepts with the Spatiotemporal Multidimensional Relational Framework
(2014-05)
The real world can be seen as containing sets of objects that have multidimensional properties and relations. Whether an agent is planning the next course of action in a task or making predictions about the future state ...
TRANSLATING VISUALIZATION INTERACTION INTO NATURAL LANGUAGE
(2014-12)
Richly interactive visualization tools are increasingly popular for data exploration and analysis in a wide variety of domains.
Recent advancements in data collection and storage call for more complex analytical tasks ...
IMAGE AND VIDEO ENHANCEMENT USING SPARSE CODING, BELIEF PROPAGATION AND MATRIX COMPLETION
(2014-12-01)
Super resolution as an exciting application in image processing was studied widely
in the literature. This dissertation presents new approaches to video super resolution,
based on sparse coding and belief propagation. ...
Studies on Deep Holes and Discrete Logarithms
(2014-05)
Error-correcting codes and cryptography are two important areas related to information communication.
Generalized Reed-Solomon codes and cryptosystems based on the discrete logarithm problem are important
representatives ...
Application of the Forward Sensitivity Method to Data Assimilation of the Lagrangian Tracer Dynamics
(2014-05)
The analysis of the dynamics of a tracer/drifter/buoy floating on the free surface of the water waves in the open ocean whose motion is described by the shallow water model equations is of great interest in Lagrangian data ...
