Your Turn

In this chapter, you’ve only touched the tip of the machine learning iceberg. (If “traditional” science is to be trusted, two-thirds of a typical iceberg is hidden underwater.) However, you have sufficiently powerful tools and knowledge for supervised and unsupervised data processing. You can set up both descriptive (regression and classification) and predictive data science experiments, somewhat assess their validity, and make non-trivial conclusions.

Congratulations! You are almost a data scientist now. (But you still need to complete the remaining projects.)
