Turkish text to speech system
(Bilkent University, 2002)
Scientists have been interested in producing human speech artificially for more than two
centuries. After the invention of computers, computers have been used in order to
synthesize speech. By the help of ...
Benefit maximizing classification using feature intervals
(Bilkent University, 2002)
For a long time, classification algorithms have focused on minimizing the quantity of
prediction errors by assuming that each possible error has identical consequences.
However, in many real-world situations, this ...
Predicting next page access by time length reference in the scope of effective use of resources
(Bilkent University, 2002)
Access log file is like a box of treasure waiting to be exploited containing
valuable information for the web usage mining system. We can convert this
information hidden in the access log files into knowledge by analyzing ...
Adaptation of multiway-merge sorting algorithm to MIMD architectures with an experimental study
(Bilkent University, 2002)
Sorting is perhaps one of the most widely studied problems of computing. Numerous
asymptotically optimal sequential algorithms have been discovered. Asymptotically
optimal algorithms have been presented for varying ...
Data decomposition techniques for parallel tree-based k-means clustering
(Bilkent University, 2002)
The main computation in the k-means clustering is distance calculations between
cluster centroids and patterns. As the number of the patterns and the number of centroids
increases, time needed to complete computations ...
Inferring phylogenetical tree by using hierarchical self organizing maps
(Bilkent University, 2002)
In biology, inferring phylogenetical tree is an attempt to describe the
evolutionary history of today’s species with the aim of finding their common ancestors.
Specifically in molecular biology, it is used in understanding ...
A content-based image retrieval system for texture and color queries
(Bilkent University, 2002)
In recent years, very large collections of images and videos have grown rapidly.
In parallel with this growth, content-based retrieval and querying the indexed collections
are required to access visual information. Two ...
Extending constrained hierarchical layout for drawing UML activity diagrams
(Bilkent University, 2002)
While modeling an object-oriented software, a visual language called Unified Modeling Language (UML)
may be used. UML is a language and notation for specification, construction, visualization, and
documentation of models ...
Modeling and animating personalized faces
(Bilkent University, 2002)
A very important and challenging problem in computer graphics is modeling
and animation of individualized face models. In this thesis, we describe a facial
modeling and animation system attempting to address this problem. ...
On-line new event detection and clustering using the concepts of the cover coefficient-based clustering methodology
(Bilkent University, 2002)
In this study, we use the concepts of the cover coefficient-based clustering
methodology (C3
M) for on-line new event detection and event clustering. The
main idea of the study is to use the seed selection process of ...
