Evaluation Criteria
You must get a Mean Absolute Error ( MAE ) score of at most 6.500 on the private holdout test-dataset to get full credit. If your MAE score is over the simple baseline, which can be found on the leaderboard, then you will get zero credit. If your MAE score is between the simple baseline and the full credit threshold, then you will be awarded points linearly proportional to your deviation from the full credit threshold. For example, if your MAE is halfway between the simple baseline and full credit threshold, then you will get half credit. Extra points will be awarded to the highest performing students, using the following scoring mechanism:

$$\text{Extra credit amount} = 5\Big(1-\frac{\text{Your Rank}-1}{\text{Total number of valid submissions}}\Big)\cdot\mathbf{1}[\text{Your score}<6.0]$$
