In this homework, you only need to upload your best test score. Since Kaggle requires at least two data rows, one for public and one for private data, you need to enter the same score twice. An example "result.csv" is shown below: Id Predicted d3_battle_pubic 20 d3_battle_private 20 Please enter your game score ( 20 in this example) into the two cells. However, we use Absolute Error (AE) as metric, and set the target as 100. So if you get a score 20 at "D3_battle.wad", you will get AE 80 on the leaderboad. Lower AE means better model. Kaggle will automatically convert your game score into AE. So the bottom line is: Please Enter Your Game Score Directly! . Additionally, you also need to submit a report to NTUT i-school.
