The evaluation metric for this competition is Weighted Accuracy estimated as follows : 

$$
Acc_w = \frac{\sum_i w_i \cdot \mathbb{1}(y_i = \hat{y}_i)}{\sum_i w_i}, \quad \text{where } w_i =
\begin{cases} 
0.4, & \text{if } y_i = 1 \text{ (cyclonic)} \\
0.4, & \text{if } y_i = 2 \text{ (anti-cyclonic)} \\
0.2, & \text{if } y_i = 0 \text{ (no eddy)}
\end{cases}
$$


This metric will concern all three classes, as so you will be evaluated regarding three values : 
$$ Acc_{cyclonic}, Acc_{anti-cyclonic}, Acc_{no-eddies} $$

## Submission File
For each ID in the test set, you must predict the eddy type: 0 for no eddy, 1 for cyclonic eddy and 2 for anticyclonic eddy. The file should contain a header and have the following format:

    ID,PREDICTED
    0_0_0,0
    0_0_1,1
    0_0_2,1
    ...
    42_0_1, 2
    etc.
