Statistical model for the reproducibility in ranking based feature selection
(2017-10-25)
Recently, concerns about the reproducibility of scientific studies have been growing among the scientific community, mainly due to the existing large quantity of irreproducible results. This has reach such an extent that ...
Bertso transformation with pattern-based sampling
(2015-08-07)
This paper presents a method to generate new melodies, based on conserving the semiotic structure of a template piece. A pattern discovery algorithm is applied to a template piece to extract significant segments: those ...
Ontologies for representation of folk song metadata
(2012)
The digital management of collections in museums, archives, libraries and galleries is an increasingly important part of cultural heritage studies. This paper describes a representation for folk song metadata, based on the ...
Oracles for audio chord estimation
(2012)
This paper explores how audio chord estimation could improve if information about chord boundaries or beat onsets is revealed by an oracle. Chord estimation at the frame level is compared with three simulations, each using ...
Music-Theoretic Estimation of Chords and Keys from Audio
(2012)
This paper proposes a new method for local key and chord estimation from audio signals. This method relies primarily on principles from music theory, and does not require any training on a corpus of labelled audio files. ...
Communities in complex networks
(2013-01-16)
The study of complex networks has attracted the attention of the scientific community for many obvious reasons. A vast number of systems, from the brain to ecosystems, power grid, and the Internet, can be represented as ...
Analysis of Spanish text-thesaurus as a complex network
(2014-02-06)
[EN]Based on the theoretical tools of Complex Networks, this work provides a basic descriptive study of a synonyms dictionary, the Spanish Open Thesaurus represented as a graph. We study the main structural measures of the ...
An R package for permutations, Mallows and Generalized Mallows models
(2014-01-22)
[EN]Probability models on permutations associate a probability value to each of the permutations on n items. This paper considers two popular probability models, the Mallows model and the Generalized Mallows model. We ...
Learning Bayesian network classifiers for multidimensional supervised classification problems by means of a multiobjective approach
(2010)
A classical supervised classification task tries to predict a single class variable based on a data set composed of a set of labeled examples. However, in many real domains more than one variable could be considered as a ...
A Preprocessing Procedure for Haplotype Inference by Pure Parsimony
(2010)
Haplotype data is especially important in the study of complex diseases
since it contains more information than genotype data. However,
obtaining haplotype data is technically difficult and expensive. Computational
methods ...
