Strategies for Handling Large Vocabulary and Data Sparsity Problems for Tamil Speech Recognition
This thesis focuses on the design and development of every building block of a very large
vocabulary, continuous speech recognition (LVCSR) system and various experiments conducted
in order to enhance its performance. ...
Robust Risk Minimization under Label Noise
In the setting of supervised learning, one learns a classi fier from training data consisting of
patterns and the corresponding labels. When labels of the examples in training data have errors,
it is referred to as label ...
Multiview Registration Using Rank-Constrained Semide nite Programming
We consider the problem of reconstructing a 3D surface from its multiview scans. Typically, the
computational pipeline for this problem has two phases: (I) finding point-to-point correspondences
between overlapping scans, ...
Visual Speech Recognition
Visual speech recognition (VSR), or automatic lip-reading, is the task of extracting speech
information from visual input. The addition of visual speech has been shown to improve
the performance of traditional audio ...
Tuning of Multi-Band Power System Stabilizers in Multi-Machine Power Systems
Intermittent nature of renewables acts as a frequent trigger for small signal oscillations in power grid. These oscillatory modes correspond to either the rotor modes associated with the synchronous machines of conventional ...
Total Electric Field due to an Electron Avalanche and it's coupling to Transmission Line Conductors
Transmission of bulk electric power from the generating stations to the load centres can be carried out only through high voltages transmission lines. One of the main issues in the design and maintenance of extra and ...
Theoretical and Algorithmic Aspects of Rigid Registration
In this thesis, we consider the rigid registration problem, which arises in applications such as
sensor network localization, multiview registration, and protein structure determination. The
abstract setup for this problem ...
Power Electronic Converters for Condition Monitoring and Voltage Equalization of Batteries
Power converters are used in battery-based storage systems in many applications. Apart from
the task of regulating the charging and discharging, the power electronic converters can also
help to monitor battery condition ...
Unidirectional High-Frequency-Link DC to Three-Phase AC Conversion: Topology, Modulation and Converter Design
In recent years, stringent restrictions on greenhouse gas emission due to the present global
warming scenario is driving governments and power utilities worldwide behind electricity generation
using renewable energy ...
One-Shot Coordination of First and Last Mode Service in Multi-Modal Transportation
In this thesis, we propose a coordination of the rst and last mode connectivity in a multi-
modal transportation system. In particular, we consider a one-shot problem wherein the
passengers must be transported to or ...
