Evolutionary Protein Contact Maps Prediction Based on Amino Acid Properties
(Springer, 2011)
Protein structure prediction is one of the main challenges in Bioinformatics. An useful representation for protein 3D structure is the protein contact map. In this work, we propose an evolutionary approach for contact ...

Support vector machines for classification of input vectors with different metrics
(ScienceDirect, 2011-05)
In this paper, a generalization of support vector machines is explored where it is considered that input vectors have different ℓp norms for each class. It is proved that the optimization problem for binary classification ...

An Evolutionary Approach for Protein Contact Map Prediction
(Springer, 2011)
In this study, we present a residue-residue contact prediction approach based on evolutionary computation. Some amino acid properties are employed according to their importance in the folding process: hydrophobicity, ...

A Tool for Web Links Prototyping
(CSREA Press, 2011)
Crawlers for Virtual Integration processes must be efficient, given that VI process is online, which means that while the system is looking for the required information, the user is waiting for a response. Therefore, ...

A Two-Stage Algorithm in Evolutionary Product Unit Neural Networks for Classification
(Elsevier, 2011-01)
This paper presents a procedure to add broader diversity at the beginning of the evolutionary process. It consists of creating two initial populations with different parameter settings, evolving them for a small number of ...

Generación de pruebas del sistema a partir de la especificación funcional
(2011)
De manera general, el proceso de prueba de software suele englobar, al menos, tres tareas principales: desarrollo de los casos de prueba, ejecución de los casos de prueba y análisis de los resultados [Burnstein, 2003]. El ...
