Hierarchical genetic algorithm
Web26 de mar. de 2012 · Our method is compared to state-of-the-art HMC algorithms, in protein function prediction datasets. The experimental results show that our approach presents competitive predictive accuracy, suggesting that genetic algorithms constitute a promising alternative to deal with hierarchical multi-label classification of biological data. Web2.3. Hierarchical Genetic Algorithms. HGA is a revised version of a genetic algorithm, which is an optimization scheme based on the biological evolution. Unlike the traditional genetic algorithm where the genotype structure is fixed, the chromosome in the HGA does not have these restrictions.
