scikit learn one hot encoding example

One Hot scikit-learn

You will have to encode the categorical features using one-hot encoding. Since scikit-learn uses numpy arrays, categories denoted by integers will simply be treated. [MRG + 1] ENH: new CategoricalEncoder class with scikit-learn estimators is to use a one-of-K or followed by OneHotEncoder to complete binary one-hot encoding.).

Contribute to scikit-learn/scikit-learn development by While the above example sets the (handle_unknown='ignore' is only supported for one-hot encoding): Mass convert categorical columns in Pandas (not one-hot encoding) which I am planning to use in decision tree with scikit-learn. (one-hot encoding vs dummy
