To binarize each of them, one could pass column names and LabelBinarizer transformer class Added elapsed time information for each feature. For example: In some situations the columns are not known before hand and we would like to dynamically select them during the fit operation. strategy = 'most_frequent' can be used only with quantitative feature, not with qualitative. This code fills in a series with the most frequent category: sklearn.impute.SimpleImputer instead of Imputer can easily resolve this, which can handle categorical variable. Lets start with an example. To use mean values for numeric columns and the most frequent value for non-numeric columns you could do something like this. imputing missing values, dealing with categorical and numerical features) that could be saved by Sklearn-Pandas.

So you don't need to use pandas.DataFrame, you can just use DataFrame instead. @cmcgrath1982 You will also require Cython >=0.23 in order to build the development version. Details: First, (from the book Hands-On Machine Learning with Scikit-Learn and TensorFlow) you can have subpipelines for numerical and string/categorical features, where each subpipeline's first transformer is a selector that takes a list of column names (and the full_pipeline.fit_transform() takes a pandas DataFrame): You can then combine these sub pipelines with sklearn.pipeline.FeatureUnion, for example: Now, in the num_pipeline you can simply use sklearn.preprocessing.Imputer(), but in the cat_pipline, you can use CategoricalImputer() from the sklearn_pandas package. These are usually helpful when using gen_features. This blog post will help you to preprocess your data just in few minutes using Sklearn-Pandas package.
