Sensitivity and specificity based multiobjective approach for feature selection: Application to cancer diagnosis
(Elsevier, 2009)
The study of the sensitivity and the specificity of a classification test constitute a powerful kind of analysis since it provides specialists with very detailed information useful for cancer diagnosis. In this work, we ...

Solving Common Algorithmic Problem by Recognizer Tissue P Systems
(Romanian Academy, 2012)
Common Algorithmic Problem is an optimization problem, which has the nice property that several other NP-complete problems can be reduced to it in linear time. In this work, we deal with its decision version in the ...

A computational modeling for real ecosystems based on P systems
(Springer, 2011)
In this paper, a P systems based general framework for modeling ecosystems dynamics is presented. Particularly, ecosystems are specified by means of multienvironment P systems composed of a finite number of environments, ...

3-Col problem modelling using simple kernel P systems
(Taylor and Francis, 2013)
This paper presents the newly introduced class of (simple) kernel P systems ((s)kP systems) and investigates through a 3-colouring problem case study the expressive power and efficiency of kernel P systems. It describes ...

Comparing simulation algorithms for multienvironment probabilistic P systems over a standard virtual ecosystem
(Springer, 2012)
Membrane Computing has recently proved to be a suitable framework for addressing the modelling of dynamical biological systems in general, and ecosystems in particular. Due to the inherent randomness and uncertainty in ...

A Study of Multiobjective Metaheuristics When Solving Parameter Scalable Problems
(IEEE Computer Society, 2010)
To evaluate the search capabilities of a multiobjective algorithm, the usual approach is to choose a benchmark of known problems, to perform a fixed number of function evaluations, and to apply a set of quality indicators. ...

Spiking Neural P systems with weights
(MIT Press, 2010)
A variant of spiking neural P systems with positive or negative weights on synapses is introduced, where the rules of a neuron fire when the potential of that neuron equals a given value. The involved values—weights, firing ...

Improving GPU Simulations of Spiking Neural P Systems
(Romanian Academy, 2012)
In this work we present further extensions and improvements of a Spiking Neural P system (for short, SNP systems) simulator on graphics processing units (for short, GPUs). Using previous results on representing SNP system ...

A Fine Grain Sentiment Analysis with Semantics in Tweets
(Universidad Internacional de La Rioja (UNIR), 2016)
Social networking is nowadays a major source of new information in the world. Microblogging sites like Twitter have millions of active users (320 million active users on Twitter on the 30th September 2015) who share ...

A P-Lingua based simulator for Tissue P systems
(Elsevier, 2010)
Investigations within the field of tissue-like P systems are being conducted, on one hand studying their computational efficiency, and on the other hand exploring the possibilities to use them as a computational modelling ...
