Abstract
um método para melhorar o desempenho de um modelo de aprendizagem de máquina treinado inclui adicionar um segundo classificador com uma segunda função objetiva a um primeiro classificador com uma primeira função objetiva. em vez de minimizar uma função de erros para o primeiro classificador, a segunda função objetiva é usada para reduzir diretamente os erros de número do primeiro classificador.
