Then why is the algorithm not able to split the the test instances with 'Sex' as one of the attributes when required, why it requires to convert the attribute 'Sex' into float to build a model. tree in the variable best_tree. This process is called feature extractionor more simply, vectorization, and is an essential first step toward language-aware analysis. The feature engineering process involves selecting the minimum required features to produce a valid model because the more features a model contains, the more complex it is (and the more sparse the data), therefore the more sensitive the model is to errors due to variance.
