Summary

In this chapter, we learned how to use Featuretools. As part of your journey as a data scientist, you will come to realize that building features is a very tedious process and involves a lot of effort and time. However, we have seen that by using Featuretools, the generation of new features is very efficient and we get a very exhaustive set of potential features that we can try on our model.

In this chapter, we approached the feature engineering step from a domain/business perspective. We identified some critical business factors and built a domain story by connecting these business factors.

We also learned about some of the critical building blocks for automated feature engineering, such as entities and entity sets. We used the domain story we formulated to create the entities and set the relationships between the parent entity and the child entities.

Once the entity set was defined, we were exposed to the basic operations for feature tools, such as aggregation and...
