Scikit-learn tools for machine learning architectures

Now we're going to present two very important scikit-learn classes that can help the machine learning engineer to create complex processing structures, including all the steps needed to generate the desired outcomes from the raw datasets.

Pipelines

Scikit-learn provides a flexible mechanism for creating pipelines made up of subsequent processing steps. This is possible thanks to a standard interface implemented by the majority of classes; therefore, most of the components (both data processors/transformers and classifiers/clustering tools) can be exchanged seamlessly. The Pipeline class accepts a single steps parameter, which is a list of tuples in the form (name of...
