In this chapter, we covered the basics of Spark ML Pipeline and its components. We saw how to train models on input DataFrame and how to evaluate their performance using standard metrics and measures while running them through spark ML pipeline APIs. We explored how to apply some of the techniques like transformers and estimators. Finally, we investigated the pipeline API by applying different algorithms on the StumbleUpon dataset from Kaggle.
Machine Learning is the rising star in the industry. It has certainly addressed many business problems and use cases. We hope that our readers will find new and innovative ways to make these approaches more powerful and extend the journey to understand the principles that hold learning and intelligence.
