“…In this approach, the way of dealing with missing values changes during the training and testing stages. During training, each value for an attribute is assigned a weight [60][61][62][63]. If an attribute value is known, then the weight is equal to one; otherwise, the weight of any other value for that attribute is the relative frequency of that attribute.…”

“…These procedures can handle missing values in any attribute for both training and test sets [59][60][61][62][63][64]. ID3 is a basic top-down decision tree algorithm that handles an unknown attribute by generating an additional edge for the unknown.…”

“…Nesse caso, o exemplo, istoé, o novo paciente, deve ser classificado com muitos valores desconhecidos. Zheng & Low (1999) analisam o uso de ensembles para aumentar a robustez dos algoritmos de aprendizado em classificar exemplos com valores desconhecidos. Na Tabela 5.1 na página oposta são apresentadas algumas das principais características dos conjuntos de dados utilizados neste estudo.…”
