Full-text available
In this paper, a high-level comparison of both SOAP (Simple Object Access Protocol) and REST (Representational State Transfer) is made. These are the two main approaches for interfacing to the web with web services. Both approaches are different and present some advantages and disadvantages for interfacing to web services: SOAP is conceptually more...
Article
This article focuses on the development of intelligent classifiers in the area of biomedicine, focusing on the problem of diagnosing cardiac diseases based on the electrocardiogram (ECG), or more precisely, on the differentiation of the types of atrial fibrillations. First of all, we will study the ECG, and the treatment of the ECG in order to work...
Conference Paper
In this paper, an overview of the main topics presented in the special session of bioinformatics and biomedical engineering is presented. Bioinformatics consists of two subfields: the development of computational tools and databases, and the application of these tools and databases in generating biological knowledge to better understand living sys...

The realization of a control unit can be done using a complex circuitry or microprogramming. The latter may be considered as an alternative method of implementation of machine instructions that can reduce the complexity and increase the flexibility of the control unit. The microcode efficiency and speed are of vital importance for the computer to e...

The realization of a control unit can be done either using a complex circuitry or microprogramming. The latter may be considered as an alternative method of implementation of machine instructions that can reduce the complexity and increase the flexibility of the control unit.

The Association of Public Andalusian Universities (AUPA) has displayed a portal that offers diverse multimedia contents related to the cultural events organized by these institutions, with object to spread this rich cultural heritage through Internet. The website, named “CaCoCu”, allows users to access to audio-visual material as audio or video rec...
Article
Paroxysmal atrial fibrillation (PAF) is one of the most common heart arrhythmias. It is very difficult to detect unless an explicit Atrial Fibrillation episode occurs during the exploration. The present paper describes a number of low level parameters extracted from ECG traces where no Atrial Fibrillation process is present. The ability of this par...
Chapter
There is a close relationship between Artificial Neural Networks (ANNs) and statistical methods in the literature because both procedures face similar classification and prediction problems, among other reasons. ANNs are largely implemented using an underlying statistical methodology sometimes, appropriately designated statistical neural networks....
Article
Full-text available
In previous work we have derived a magnitude termed the 'Mean Squared Sensitivity' (MSS) to predict the performance degradation of a MLP affected by perturbations in different parameters. The present Letter continues the same line of researching, applying a similar methodology to deal with RBF networks and to study the implications when they are af...
Article
This paper proposes a framework for constructing and training a radial basis function (RBF) neural network. For this purpose, a sequential learning algorithm is presented to adapt the structure of the network, in which it is possible to create a new hidden unit and also to detect and remove inactive units. The structure of the Gaussian functions is...
Article
Full-text available
An analysis of the influence of weight and input perturbations in a multilayer perceptron (MLP) is made in this article. Quantitative measurements of fault tolerance, noise immunity, and generalization ability are provided. From the expressions obtained, it is possible to justify some previously reported conjectures and experimentally obtained resu...
Conference Paper
Full-text available
In this article, a real-coded genetic algorithm (GA) is proposed capable of simultaneously optimizing the structure of a system (number of inputs, membership functions and rules) and tuning the parameters that define the fuzzy system. A multideme GA system is used in which various fuzzy systems with different numbers of input variables and with dif...
Conference Paper
Previous works have demonstrated that Mean Squared Sensitivity (MSS) constitutes a good aproximation to the performance degradation of a MLP affected by perturbations. In the present paper, the expression of MSS for Radial Basis Function Neural Networks affected by additive noise in their inputs is obtained. This expression is experimentally valida...
Article
The main architectures, learning abilities and applications of radial basis function (RBF) neural networks are well documented. However, to the best of our knowledge, no in-depth analyses have been carried out into the influence on the behaviour of the neural network arising from the use of different alternatives for the design of an RBF (different...
Conference Paper
Full-text available
The inherent fault tolerance of artificial neural networks (ANNs) is usually assumed, but several authors have claimed that ANNs are not always fault tolerant and have demonstrated the need to evaluate their robustness by quantitative measures. For this purpose, various alternatives have been proposed. In this paper we show the direct relation betw...
Conference Paper
The fine grain, data-driven parallelism shown by neural models as the Boltzmann machine cannot be implemented in an entirely efficient way either in general-purpose multicomputers or in networks of computers, which are nowadays the most common parallel computer architectures. In this paper we present a parallel implementation of a modified Boltzma...
Conference Paper
This paper presents the results obtained by a new parallel procedure that generates the patterns for testing digital circuits when it is implemented in a shared-memory multiprocessor. The procedure is based on a new sequential algorithm which mixes both the Boolean difference and digital spectral techniques, thus being different from other paralle...
Conference Paper
Full-text available
A modified backpropagation algorithm that minimizes the sensitivity to weight errors is presented. Multi-Layer Perceptrons (MLPs) trained with this algorithm are more tolerant to weight deviations compared to those obtained with a classical algorithm while the other performance figures are similar. Thus the algorithm is useful for MLPs that are goi...

MasterMind is a game in which the player must find out, by making guesses, a hidden combination of colors set by the opponent. The player lays a combination of colors, and the opponent points out the number of positions the player has found out (black tokens) and the number of colors that are in a different place from the hidden combination (white...

This paper studies the viability of a skin lesion diagnosis scheme based on fluorescence images. Three kinds of skin lesions are considered: actinitic keratosis, basal cell carcinoma and psoriasis. A wide and diverse set of simple parameters have been extracted and their discrimination potential is evaluated through an automatic diagnosis scheme ba...

Navigation using web pages began about ten years ago in scientific and academic circles. This technology later became available to the rest of society in general and to the commercial world in particular, but the pioneers of the web were researchers and university teachers. Today, however, commercial websites offer a great variety of services, whil...
