A compact evolutionary interval-valued fuzzy rule-based classification system for the modeling and prediction of real-world financial applications with imbalanced data
(IEEE, 2014)
Artículo / Artikulua,
The current financial crisis has stressed the need of obtaining more accurate prediction models in order to decrease the risk when investing money on economic opportunities. In addition, the transparency of the process ...
INFFC: an iterative class noise filter based on the fusion of classifiers with noise sensitivity control
(Elsevier, 2015)
Artículo / Artikulua,
In classification, noise may deteriorate the system performance and increase the complexity of the models built. In order to mitigate its consequences, several approaches have been proposed in the literature. Among them, ...
CSigma graphs: a new approach for plasma characterization in laser-induced breakdown spectroscopy
(Elsevier, 2014)
Artículo / Artikulua,
A generalization of curves of growth called CSigma (Cσ) graphs, which allows including several lines of various elements in the same ionization state at different concentrations, is proposed for laser-induced breakdown ...
Method for measurement of transition probabilities by laser-induced breakdown spectroscopy based on CSigma graphs. Application to Ca II spectral lines
(Elsevier, 2015)
Artículo / Artikulua,
We propose a method for determination of transition probabilities by laser-induced breakdown spectroscopy that avoids the error due to self-absorption. The method relies on CSigma graphs, a generalization of curves of ...

Using the Choquet integral in the fuzzy reasoning method of fuzzy rule-based classification systems
(MDPI, 2013)
Artículo / Artikulua,
In this paper we present a new fuzzy reasoning method in which the Choquet
integral is used as aggregation function. In this manner, we can take into account the
interaction among the rules of the system. For this reason, ...
Market sentiment: a key factor of investors' imitative behaviour
(Wiley, 2012)
Artículo / Artikulua,
The aim of this paper is to explore herding behavior among investors in order to determine its rational and emotional component factors and identify relationships among them. We apply causality tests to evaluate the impact ...
Value of analysts’ consensus recommendations and investor sentiment
(Taylor & Francis, 2013)
Artículo / Artikulua,
This paper studies the effect of investor sentiment on analysts' consensus recommendations. Our results show that the optimistic bias of analysts in the issuing of recommendations is affected by investor sentiment: the ...
