A Preprocessing Procedure for Haplotype Inference by Pure Parsimony
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 ... -
A review on Estimation of Distribution Algorithms in Permutation-based Combinatorial Optimization Problems
Ceberio Uribe, Josu; Irurozki, Ekhine; Mendiburu Alberro, Alexander; Lozano Alonso, José Antonio (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 ... -
An R package for permutations, Mallows and Generalized Mallows models
[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 ... -
Extending Distance-based Ranking Models In Estimation of Distribution Algorithms
Ceberio Uribe, Josu; Irurozki, Ekhine; Mendiburu Alberro, Alexander; Lozano Alonso, José Antonio (2014-05-20)
Recently, probability models on rankings have been proposed in the field of estimation of distribution algorithms in order to solve permutation-based combinatorial optimisation problems. Particularly, distance-based ranking ... -
Learning Probability Distributions over Permutations by Means of Fourier Coefficients
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, ... -
Sampling and learning the Mallows and Generalized Mallows models under the Cayley distance
[EN]The Mallows and Generalized Mallows models are compact yet powerful and natural ways of representing a probability distribution over the space of permutations. In this paper we deal with the problems of sampling and ... -
Sampling and learning the Mallows and Weighted Mallows models under the Hamming distance
[EN]In this paper we deal with distributions over permutation spaces. The Mallows model is the mode l in use. The associated distance for permutations is the Hamming distance. -

Irurozki, Ekhine; Ceberio Uribe, Josu; Calvo Molinos, Borja
; Lozano Alonso, José Antonio (2014-01-22)
[EN]In this paper we deal with probability distributions over permutation spaces. The Probability model in use is the Mallows model. The distance for permutations that the model uses in the Ulam distance.
