You work for an online travel agency that also sells advertising placements on its website to other companies. Your task is to build a system to predict the most relevant web banner that a user should see next based on their navigation context.

The website handles thousands of web banners, and your exploratory data analysis indicates that a user's navigation context is a valuable predictor for the next banner. You want to implement the simplest solution that meets these requirements. How should you configure the prediction pipeline?
