A cost-sensitive learning algorithm for fuzzy rule-based classifiers
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2004)
Article
Open AccessDesigning classifiers may follow different goals. Which goal to prefer among others depends on the given cost situation and the class distribution. For example, a classifier designed for best accuracy in terms of ... -
A fuzzy inductive approach for rule-based modelling of high level structures in algorithmic composition systems
(2015)
Conference report
Restricted access - publisher's policyAlgorithmic composition systems are now widely understood. However, its capacity for producing outputs consistently showing high level structures is still a field of research. In the present work, the Fuzzy Inductive ... -
A generaliser applied to SBL
(1992-03)
Research report
Open AccessIn this work two algorithms have been developed: a generaliser and a hierarchy constructor. The generaliser receives as inputs the descriptions of some positive examples of a concept and it calculates their maximal conjunctive ... -

A method for assessing parameter impact on control-flow discovery algorithms
(CEUR-WS.org, 2015)
Conference report
Open AccessGiven an event log L, a control-flow discovery algorithm f, and a quality metric m, this paper faces the following problem: what are the parameters in f that mostly influence its application in terms of m when applied ... -
A methodology for distributed fault diagnosis
(2016)
Conference report
Restricted access - publisher's policyIn this paper, a methodology for distributed fault diagnosis is proposed. The algorithm places the sensors in a system in such a manner that the partition of a system into various subsystems becomes ... -
A modification of the Lloyd algorithm for k-anonymous quantization
(2013-02-10)
Article
Open AccessWe address the problem of designing quantizers that cluster data while satisfying a k-anonymity requirement. A general data compression perspective is adopted, which considers both discrete and continuous probability ... -
A novel procedure for training L1-L2 support vector machine classifiers
(2013)
Conference report
Restricted access - publisher's policyIn this work we propose a novel algorithm for training L1-L2 Support Vector Machine (SVM) classifiers. L1-L2 SVMs allow to combine the effectiveness of L2 models and the feature selection characteristics of L1 solutions. ... -
A one pass algorithm for type checking with overloading and polymorphism
(1992-05-24)
Research report
Open AccessThis paper presents an algorithm to do type checking with overloaded functions. It also handles type variables, which enables it to handle polymorphic functions and other interesting problems as incomplete programs. The ... -
A parallel dynamic asynchronous framework for uncertainty quantification by hierarchical Monte Carlo algorithms
(Springer Nature, 2021-09-13)
Article
Open AccessThe necessity of dealing with uncertainties is growing in many different fields of science and engineering. Due to the constant development of computational capabilities, current solvers must satisfy both statistical ... -
A second-order distributed Trotter–Suzuki solver with a hybrid CPU–GPU kernel
