Discovering Frequent Episodes With General Partial Orders
(2013-06-04)
Pattern Discovery, a popular paradigm in data mining refers to a class of techniques that try and extract some unknown or interesting patterns from data. The work carried out in this thesis concerns frequent episode mining, ...
Hierarchical Logcut : A Fast And Efficient Way Of Energy Minimization Via Graph Cuts
(2013-06-10)
Graph cuts have emerged as an important combinatorial optimization tool for many problems in vision. Most of the computer vision problems are discrete labeling problems. For example, in stereopsis, labels represent disparity ...
Spectro-Temporal Features For Robust Automatic Speech Recognition
(2011-01-18)
The speech signal is inherently characterized by its variations in time, which get reflected as variations in frequency. The specto temporal changes are due to changes in vocaltract, intonation, co-articulation and successive ...
Guessing And Compression : A Large Deviations Approach
(2011-04-01)
The problem of guessing a random string is studied. It arises in the analysis of the strength of secret-key cryptosystems against guessing attacks. Expected number of guesses, or more generally moments of the number of ...
Lexicon-Free Recognition Strategies For Online Handwritten Tamil Words
(2014-08-07)
In this thesis, we address some of the challenges involved in developing a robust writer-independent, lexicon-free system to recognize online Tamil words. Tamil, being a Dravidian language, is morphologically rich and also ...
A Research Bed For Unit Selection Based Text To Speech Synthesis System
(2011-08-09)
After trying Festival Speech Synthesis System, we decided to develop our own TTS framework, conducive to perform the necessary research experiments for developing good quality TTS for Indian languages. In most of the ...
