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 ...

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) ...

Thematic issue on human-centred ambient intelligence: Cognitive approaches, reasoning and learning
(IOS Press, 2017-08)
This editorial presents advances on Human-centred Ambient Intelligence applications which take into account cognitive issues when modelling users (i.e. stress, attention disorders), and learn users’ activities/preferences ...

A study on output normalization in multiclass SVMs
(ScienceDirect, 2013-02)
The use of binary support vector machines (SVMs) in multi-classification is addressed in this paper. Margins associated to the bi-classifiers, since they depend on the geometrical disposition of the classes being separated, ...

Energy wasting at internet data centers due to fear
(Elsevier, 2015)
The fear experienced by data center administrators presents an ongoing problem due to the low percentage of machines that they are willing to switch off in order to save energy. This risk aversion can be assessed from ...

Measures of Similarity Between Objects Based on Qualitative Shape Descriptions
(Taylor & Francis, 2013-06)
A computational approach for comparing qualitative shape descriptions (QSDs) of objects within digital images is presented. First, the dissimilarity of qualitative features of shape is measured: (i) intuitively using ...
