Embedded heterogeneous feature selection for conjoint analysis: A SVM approach using L1 penalty
(Springer, 2017)
This paper presents a novel embedded feature selection approach for Support Vector Machines (SVM) in a choice-based conjoint context. We extend the L1-SVM formulation and adapt the RFE-SVM algorithm to conjoint analysis ...
Orthogonal function representation for online signature verification: Which features should be looked at?
(Wiley, 2013-07)
In this study, several feature combinations are studied to analyse their relevance for online signature verification. Different time functions associated with the signing process are analysed in order to provide some insight ...
Legendre polynomials based feature extraction for online signature verification. Consistency analysis of feature combinations
(Elsevier, 2014-01)
In this paper, feature combinations associated with the most commonly used time functions related to the signing process are analyzed, in order to provide some insight on their actual discriminative power for online signature ...

Rock lithological classification using multi-scale Gabor features from sub-images, and voting with rock contour information
(Elsevier, 2015)
Estimation of rock composition in mining plants is important for determining rock size and grindability which, in turn, may improve control of the grinding process. Variations in ore grindability and size distribution ...
Computational methods for pigmented skin lesion classification in images: review and future trends
(Springer, 2018-02-01)
Skin cancer is considered as one of the most common types of cancer in several countries, and its incidence rate has increased in recent years. Melanoma cases have caused an increasing number of deaths worldwide, since ...
