Stability of time-delay systems via Lyapunov functions
(Hindawi Publishing Corporation, 2002)
Artículo / Artikulua,
In this paper, a Lyapunov function candidate is introduced for multivariable systems with inner delays, without assuming a priori stability for the nondelayed subsystem. By using this Lyapunov function, a controller is ...
Aggregation functions to combine RGB color channels in stereo matching
(Optical Society of America, 2013)
Artículo / Artikulua,
In this paper we present a comparison study between different
aggregation functions for the combination of RGB color channels in stereo
matching problem. We introduce color information from images to the
stereo matching ...
Web browsing interactions inferred from a flow-level perspective
(2015)
Tesis doctoral / Doktoretza tesia,
Desde que su uso se extendiera a mediados de los noventa, la web ha sido probablemente el servicio de Internet más popular. De hecho, muchos usuarios la utilizan prácticamente como sinónimo de Internet. Hoy en día los ...
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, ...
A survey of fingerprint classification Part I: taxonomies on feature extraction methods and learning models
(Elsevier, 2015)
Artículo / Artikulua,
This paper reviews the fingerprint classification literature looking at the problem from a double perspective. We first deal with feature extraction methods, including the different models considered for singular point ...
The use of two relations in L-fuzzy contexts
(Elsevier, 2015)
Artículo / Artikulua,
In the analysis of relations among the elements of two sets it is usual to obtain different values depending on the point of view from which these relations are measured. The main goal of the paper is the modelization of ...
Enhancing multi-class classification in FARC-HD fuzzy classifier: on the synergy between n-dimensional overlap functions and decomposition strategies
(IEEE, 2014)
Artículo / Artikulua,
There are many real-world classification problems involving multiple classes, e.g., in bioinformatics, computer vision or medicine. These problems are generally more difficult than their binary counterparts. In this scenario, ...
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, ...
Image reduction using means on discrete product lattices
(IEEE, 2012)
Artículo / Artikulua,
We investigate the problem of averaging values on
lattices, and in particular on discrete product lattices. This
problem arises in image processing when several color values
given in RGB, HSL, or another coding scheme, ...
