n_onesan specifies a number of onesans. If n_onesan == 1, Onesan would run alone. If n_onesan >= 2, Onesan would fission into child processes and runs almost n_onesan times faster.

evaluator specifies the evaluation metrics for resulting classification performance. evaluator takes callable object which takes 2 arguments, true label t and prediction y. sklearn.metrics.precision_recall_fscore_support will be chosen by default.

We can specify the classifier onesan uses.
The classifier must have fit and predict method to training and validation the model.
classifier shold inherit sklearn.base.BaseEstimator.
