Pipelinecan be used to chain multiple estimators into one. This is useful as there is often a fixed sequence of steps in processing the data, for example feature selection, normalization and classification.Pipelineserves multiple purposes here: Convenience and encapsulation You only have to callfitan...
这种类型的预处理器可以用管道(Pipeline)集成为一个工作流。 这样就可以用单个对象表示一个简单的多项式回归器,如下所示:>>> from sklearn.preprocessing import PolynomialFeatures >>> from sklearn.linear_model import LinearRegression >>> from sklearn.pipeline import Pipeline >>> import numpy as np >>>...

I have created an MLPRegressor that functions as an auto-encoder: clf = MLPRegressor(hidden_layer_sizes = [100,50,100], verbose=True, activation='logistic') pipeline = Pipeline([ ('scaler', StandardScaler()), ('clf', clf) ]) pipeline.fit...
it can be used in a streaming (partial fit) or parallel pipeline as there is no state computed during fit. There are also a couple of cons (vs using a CountVectorizer with an in-memory vocabulary): there is no way to compute the inverse transform (from feature indices to string feature...
