Binarizer transforms continuous values to two states (0 or 1). It would be nice to generalize this to an arbitrary number of states K. This preprocessor would produce a scipy sparse matrix of shape (n_samples, K * n_features) using the one-of-K encoding. The K thresholds could be chosen uniformly between the min and max of each feature or using the K-quantiles. For example, using uniformly chosen
