Chapter 9 Working with Profile Data

What even is profile data???

It’s sort of like Inception

Profile data refers to datasets that have complex hierarchcical relationships.An example would be if you’re trying to predict whether a student would pass a course. You might have demographic data on that student, but you’d probably also have data on the courses they took, absences grades etc.. There might also be a time component related to how quickly they’re finishing their degree. There are a lot of layers to this, and feature engineering can help us create better models, insofar as we understand the data’s structure.

Learning objectives:

• Be able to preprocess profile data to make adequate predictions
