Discriminant ECOC: a heuristic method for application dependent design of error correcting output codes
TLDR
We present a heuristic method for learning error correcting output codes matrices based on a hierarchical partition of the class space that maximizes a discriminative criterion. Expand

Traffic Sign Recognition Using Evolutionary Adaboost Detection and Forest-ECOC Classification
TLDR
The high variability of sign appearance in uncontrolled environments has made the detection and classification of road signs a challenging problem in computer vision. Expand

Nonparametric discriminant analysis and nearest neighbor classification
TLDR
Nonparametric discriminant analysis (NDA), opposite to other nonparametric techniques, has received little attention within the pattern recognition community. Expand

Learning mixture models using a genetic version of the EM algorithm
TLDR
We propose a genetic algorithm to combine different solutions in a stochastic search so as to produce better results in a complex structure where the classical EM algorithm normally fails. Expand

Introducing a weighted non-negative matrix factorization for image classification
TLDR
A comparison between NMF, WNMF and the well-known principal component analysis (PCA) in the context of image patch classification has been carried out. Expand

Intestinal Motility Assessment With Video Capsule Endoscopy: Automatic Annotation of Phasic Intestinal Contractions
TLDR
We propose a machine learning system to automatically detect the phasic intestinal contractions in video capsule endoscopy, driving a useful but not feasible clinical routine into a feasible clinical procedure. Expand
