I am trying to solve the assignment on the Sérindipité article recommendation. I implemented the code as demonstrated in the module from non-personalized recommender systems. Now I am stuck.
- do we need to build a model and use the train data for calculating the 100*RMSE on the test data?
- is the sample submission meant as example of how the final result should look like or do we need use it for calculating the 100*RMSE?
Please help me to finalize this assignment.
Thanks a lot
