Learning Probability Distributions over Permutations by Means of Fourier Coefficients
Irurozki, Ekhine; Calvo Molinos, Borja; (2011)
A large and increasing number of data mining domains consider data that can be represented as permutations. Therefore, it is important to devise new methods to learn predictive models over datasets of permutations. However, ... -
A review on Estimation of Distribution Algorithms in Permutation-based Combinatorial Optimization Problems
Ceberio Uribe, Josu; Irurozki, Ekhine; ; (2011)
Estimation of Distribution Algorithms (EDAs) are a set of algorithms that belong to the field of Evolutionary Computation. Characterized by the use of probabilistic models to represent the solutions and the dependencies ... -

Analyzing limits of effectiveness in different implementations of estimation of distribution algorithms
Echegoyen Arruti, Carlos; Zhang, Qingfu; ; Santana Hermida, Roberto; (2011)
Conducting research in order to know the range of problems in which a search algorithm is effective constitutes a fundamental issue to understand the algorithm and to continue the development of new techniques. In this ... -
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. ... -
Learning from human teaching strategies
Ruiz, Samara; Urretavizcaya, Maite; Fernández de Castro, Isabel (2012)
Recent works in the area of adaptive education systems point out the importance of aumenting the student model to improve the personalization and adaptation to the learner by means of several aspects such as emotions, user ... -
Obtaining teaching expertise from F2F learning interactions
Ruiz, Samara; Urretavizcaya, Maite; Fernández de Castro, Isabel (2012)
Learning environments are commonly used nowadays, but they exclude face-to-face interaction among teachers and students what is a successful basis of traditional education. On the other hand, in many cases teachers are ... -
Estudio bibliográfico de sistemas educativos en el ámbito de la inteligencia artificial

Este informe trata de reunir en un documento la revisión bibliográfica realizada como base necesaria para el desarrollo de una tesis doctoral sobre las interacciones entre profesores y alumnos en las sesiones tradicionales ... -
Using network mesures to test evolved NK-landscapes
Santana Hermida, Roberto; ; (2012)
In this paper we empirically investigate which are the structural characteristics that can help to predict the complexity of NK-landscape instances for estimation of distribution algorithms. To this end, we evolve instances ... -

In recent years, participatory approaches have been incorporated in decision-making processes as a way to strengthen the bonds between diverse areas of knowledge and social actors in natural resources management and ... -
Towards a participatory integrated assessment approach for planning and managing Natura 2000 network sites
Etxano Gandariasbeitia, Iker; ; ; Hoyos Ramos, David ; ; ; Lozano Valencia, Pedro José (Basque Centre for Climate Change/Klima Aldaketa Ikergai, 2012-10)
Managing protected areas implies dealing with complex social-ecological systems where multiple dimensions (social, institutional, economic and ecological) interact over time for the delivery of ecosystem services. ... -
New methods for generating populations in Markov network based EDAs: Decimation strategies and model-based template recombination
Santana Hermida, Roberto; ; (2012-12-27)
Methods for generating a new population are a fundamental component of estimation of distribution algorithms (EDAs). They serve to transfer the information contained in the probabilistic model to the new generated population. ... -
