Support vector machines for classification of input vectors with different metrics
(ScienceDirect, 2011-05)
In this paper, a generalization of support vector machines is explored where it is considered that input vectors have different ℓp norms for each class. It is proved that the optimization problem for binary classification ...

Support vector machines for interval discriminant analysis
(ScienceDirect, 2008-03)
The use of data represented by intervals can be caused by imprecision in the input information, incompleteness in patterns, discretization procedures, prior knowledge insertion or speed-up learning. All the existing support ...

A similarity measure between videos using alignment, graphical and speech features
(ScienceDirect, 2012)
A novel video similarity measure is proposed by using visual features, alignment distances and speech transcripts. First, video files are represented by a sequence of segments each of which contains colour histograms, ...

A model for the qualitative description of images based on visual and spatial features
(ScienceDirect, 2012)
An approach that provides a qualitative description of any image is presented in this paper. The main visual features (shape and colour) and the main spatial features (fixed orientation, relative orientation and topology) ...
