CTR-Prediction
Click-through rate (CTR) is a very important metric for evaluating ad performance in online advertising. As a result, click prediction systems are essential and widely used for sponsored search and real-time bidding. In our dataset, we have provided 11 days’ worth of Avazu data to build and test prediction models.
ad_response_tutorial
This tutorial shows users how to evaluate advertising response using last click attribution, experiments, marketing mix models and attribution models. By applying these methods to the same (synthetic) data set, users will learn how the methods compare. We also illustrate the data manipulation that is required to prepare typical raw advertising data for analysis. Examples are worked in R and slides are provided in LaTeX.

It contains questions regarding the use of SQL, the implementation of a database solution for a certain problem, the creation of a research poster on how Big Data helps fight fraud and a bigger and more creative task revolving around acquiring data and exploring it, with visualisation and coming up with ideas on how to productively use it.
