Exercise

Implicit vs. explicit data

As mentioned in the video exercise, feedback used in recommendation engines can be explicit or implicit.

The dataset listening_history_df has been loaded for you. This dataset contains columns identifying the users, the songs they listen to, along with:

  • Skipped Track: A Boolean column recording whether the user skipped the song or listened to it to the end.
  • Rating: The score out of 10 the user gave the song.

In this exercise, you will explore the data and from this exploration identify which columns best reflect explicit feedback versus implicit feedback.
