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, ...

Measuring the Quality of Shifting and Scaling Patterns in Biclusters
(Springer, 2010)
The most widespread biclustering algorithms use the Mean Squared Residue (MSR) as measure for assessing the quality of biclusters. MSR can identify correctly shifting patterns, but fails at discovering biclusters presenting ...

CarGene: Characterisation of sets of genes based on metabolic pathways analysis
(Inderscience, 2011)
The great amount of biological information provides scientists with an incomparable framework for testing the results of new algorithms. Several tools have been developed for analysing gene-enrichment and most of them ...

Evolutionary Metaheuristic for Biclustering based on Linear Correlations among Genes
(Association for Computing Machinery (ACM), 2010)
A new measure to evaluate the quality of a bicluster is proposed in this paper. This measure is based on correlations among genes. Moreover, a new evolutionary metaheuristic based on Scatter Search, which uses this ...

Alpha Helix Prediction Based on Evolutionary Computation
(Springer, 2010)
Multiple approaches have been developed in order to predict the protein secondary structure. In this paper, we propose an approach to such a problem based on evolutionary computation. The proposed ap proach considers ...

Evolutionary Biclustering based on Expression Patterns
(IEEE Computer Society, 2011)
The majority of the biclustering approaches for microarray data analysis use the Mean Squared Residue (MSR) as the main evaluation measure for guiding the heuristic. MSR has been proven to be inefficient to recognize ...

A Hybrid Metaheuristic for Biclustering Based on Scatter Search and Genetic Algorithms
(Springer, 2009)
In this paper a hybrid metaheuristic for biclustering based on Scatter Search and Genetic Algorithms is presented. A general scheme of Scatter Search has been used to obtain high–quality biclusters, but a way of generating ...

Correlation–Based Scatter Search for Discovering Biclusters from Gene Expression Data
(Springer, 2010)
Scatter Search is an evolutionary method that combines ex isting solutions to create new offspring as the well–known genetic algo rithms. This paper presents a Scatter Search with the aim of finding biclusters from gene ...

A novel approach for avoiding overlapping among biclusters in expression data
(IEEE Computer Society, 2008)
Biclustering is a technique used in analysis of microarray data. It aims at discovering subsets of genes that presents the same tendency under a subsest of experimental conditions. Various techniques have been introduced ...

Searching for Rules to find Defective Modules in Unbalanced Data Sets
(IEEE Xplore, 2009-05)
The characterisation of defective modules in software engineering remains a challenge. In this work, we use data mining techniques to search for rules that indicate modules with a high probability of being defective. Using ...
