Semi-Supervised Classification Using Gaussian Processes
(2010-03-26)
Gaussian Processes (GPs) are promising Bayesian methods for classification and regression problems. They have also been used for semi-supervised classification tasks. In this thesis, we propose new algorithms for solving ...
Explicit Segmentation Of Speech For Indian Languages
(2010-07-02)
Speech segmentation is the process of identifying the boundaries between words, syllables or phones in the recorded waveforms of spoken natural languages. The lowest level of speech segmentation is the breakup and ...
Boxicity, Cubicity And Vertex Cover
(2010-09-28)
The boxicity of a graph G, denoted as box(G), is the minimum dimension d for which each vertex of G can be mapped to a d-dimensional axis-parallel box in Rd such that two boxes intersect if and only if the corresponding ...
The Isoperimetric Problem On Trees And Bounded Tree Width Graphs
(2010-08-26)
In this thesis we study the isoperimetric problem on trees and graphs with bounded treewidth. Let G = (V,E) be a finite, simple and undirected graph. For let δ(S,G)= {(u,v) ε E : u ε S and v ε V – S }be the edge boundary ...
