GAWO: Genetic-based optimization algorithm for SMT
Résumé
In this work, we propose GAWO, a new method for SMT parameters optimization based on the genetic algorithms. Like other existing methods, GAWO performs the optimization task through two nested loops, one for the translation and the other for the optimization. However, our proposition is especially designed to optimize the feature weights of the fitness function of GAMaT, a new genetic-based decoder for SMT. We tested GAWO to optimize GAMaT for French-English and Turkish-English translation tasks, and the results showed that we out-perform the previous performance by +4.0 points according to the BLEU for French-English and by +2.2 points for Turkish-English.
