Pattern Recognition Theory
A Genetic Algorithm for Constructing Compact Binary Decision Trees 1-13
Sung-Hyuk Cha, Charles C Tappert
Tree-based classifiers are important in pattern recognition and have been well studied. Although the problem of finding an optimal decision tree has received attention, it is a hard optimization problem.

GrepVS - a Combined Approach for Graph Matching 14-31
Diego Reforgiato Recupero
Next-generation database systems dealing with biomedical data, web relationships, network directories and structured documents often model the data as graphs.

Validation Index for Transactional Clustering 79-91
Piyang Wang, W. M. Ma, Tommy W. S. Chow
A new Transactional clustering validation (TCV) index for transactional data is proposed. Due to the poor structure nature of transactional data, conversional validation indices are hardly applicable to this kind of data directly.

Data Adaptive Simultaneous Parameter and Kernel Selection in Kernel Discriminant Analysis Using Information Complexity 119-132
Caterina Liberati, J. Andrew Howe, Hamparsum Bozdogan
Kernel Discriminant Analysis (KDA) is the usual extension of Fisher Linear Discriminant Analysis (FLDA) in a high dimensional feature space via kernel mapping.

Behavioral Pattern Learning Models for Decision Making in Games 133-151
Yaron Lahav
This paper presents and tests a new learning model of boundedly rational players interacting with nature. According to the model, players look back on the history of choices made by nature and search for patterns.

Applications
Dynamic Time Warping Based Static Hand Printed Signature Verification 52-65
Jayadevan R, Satish R Kolhe, Pradeep M Patil
Static signature verification has a significant use in establishing the authenticity of bank checks, insurance and legal documents based on the signatures they carry.

QMOS - a Robust Visualization Method for Speaker Dependencies With Different Microphones 32-51
Andreas Maier, Maria Schuster, Ulrich Eysholdt, Tino Haderlein, Tobias Cincarek, Stefan Steidl, Anton Batliner, Stefan Wenhardt, Elmar Nöth
There are several methods to create visualizations of speech data. All of them,however, lack the ability to remove microphone-dependent distortions.

Illumination Chromaticity Estimation Using Linear Learning Methods 92-109
Vivek Agarwal, Andrei Gribok, Andreas Koschan, Besma R. Abidi, Mongi A. Abidi
In this paper, we present the application of linear machine learning techniques, ridge regression and kernel regression for the estimation of illumination chromaticity.

Processor Abstraction in Computer System Models 66-78
Ilya Gluhovsky
Performance models for computer systems are widely used to evaluatearchitectural tradeoffs early in the design cycle and to project thebehavior of a given workload on a proposed architecture.
