In the last chapter, we learned about the predictive analytics process; we also learned about some of the fundamental definitions and the main libraries in the Python data ecosystem. In this chapter, we will start getting our hands on a couple of datasets and delve deeper into the first and second phases of the predictive analytics process: Problem understanding and definition and Data collection and preparation.
In the first part of this chapter, we talk about some of the most important considerations when defining and understanding the problem: having enough context and domain knowledge about the problem, and defining what is being predicted and the data that we have to work with. This phase also includes proposing a solution; we talk about some of the main topics to consider.
We put this idea into practice in the second part of the...
