Data Reduction Method for Categorical Data Clustering
(Springer Verlag, 2008)
Categorical data clustering constitutes an important part of
data mining; its relevance has recently drawn attention from several researchers.
As a step in data mining, however, clustering encounters the
problem of large ...
Information theory tools for viewpoint selection, mesh saliency and geometry simplification
(Springer, 2009)
In this chapter we review the use of an information channel as a unified framework for viewpoint selection, mesh saliency and geometry simplification. Taking the viewpoint distribution as input and object mesh polygons as ...
Melodic track identification in MIDI files considering the imbalanced context
(Springer Verlag (Germany), 2009)
In this paper, the problem of identifying the melodic track of a MIDI file in imbalanced scenarios is addressed. A polyphonic MIDI file is a digital score that consists of a set of tracks where usually only one of them ...
A template-based recognition system for on-line handwritten characters
(Institute of Information Science, Academia Sinica, 2009)
New developments on our real-time recognition engine for isolated handwritten
characters are presented. This engine is based on approximate Dynamic Time Warping
comparisons with prototypes selected by fast, less accurate ...
Octahedral Transforms for 3D Image Processing
(Institute of Electrical and Electronics Engineers, 2009)
The octahedral group is one of the finite subgroups
of the rotation group in three-dimensional Euclidean space and
a symmetry group of the cubic grid. Compression and filtering
of three-dimensional volumes are given as ...
Ontology integration using mappings: towards getting the right logical consequences
(Springer Verlag (Germany), 2009)
We propose a general method and novel algorithmic techniques to facilitate the integration of independently developed ontologies using mappings. Our method and techniques aim at helping users understand and evaluate the ...
Multidimensional integrated ontologies: a framework for designing semantic data warehouses
(Springer Verlag (Germany), 2009)
The Semantic Web enables companies and organizations to gather huge amounts of valuable semantically annotated data concerning their subjects of interest. Nowadays, many applications attach metadata and semantic annotations ...
Exploring early classification strategies of streaming data with delayed attributes
(Springer Verlag (Germany), 2009)
In contrast to traditional machine learning algorithms, where all data are available in batch mode, the new paradigm of streaming data poses additional difficulties, since data samples arrive in a sequence and many hard ...
Filter banks for hyperspectral pixel classification of satellite images
(Springer Verlag (Germany), 2009)
Satellite hyperspectral imaging deals with heterogenous images containing different texture areas. Filter banks are frequently used to characterize textures in the image performing pixel classification. This filters are ...
Dealing with inaccurate face detection for automatic gender recognition with partially occluded faces
(Springer Verlag (Germany), 2009)
Gender recognition problem has not been extensively studied in situations where the face cannot be accurately detected and it also can be partially occluded. In this contribution, a comparison of several
characterisation ...
