Abstract
For prescriptive analytics applications, data science teams need to design, build and maintain complex machine learning pipelines. In this talk, we demonstrate how such pipelines can be implemented in a robust, scalable and extensible manner using Python, Luigi, PySpark and scikit-learn.
Description
Data science teams working on real-world prescriptive analytics applications face the challenge to design, build and maintain considerably complex machine learning pipelines on a daily basis. Such pipelines include parsing data from multiple data sources, extracting relevant predictive features, executing training, validation, prediction steps and finally optimizing actions to meet desired business outcome so that they can be shared and visualized to business users. In this talk, we demonstrate how such pipelines can be implemented end-to-end in a robust, scalable and extensible manner using Python, Luigi, PySpark and scikit-learn. We will share our lessons learned from using this framework in a real-world demand forecasting use case.
