Final prediction on countries different from A,B,C

Thinking in a generalization of the model - will the model be tested with a different country on the final prediction test, like for example country “D”? or can we focus on 3 different (A,B,C) countries?

Good question,

Predictions for each country will be scored separately and averaged together. On our end, it doesn’t matter if your approach uses one generalized model to make the predictions or a separate model for each country–it’s up to you! As long the predictions conform to the submission format specified in the problem description, we can compute your score.

Good luck!
