Evaluation Metric

Hi Zindi,
Please look at the testing data, there are no negative values to evaluate on, FN will always be equal to zero (0) !
The evaluation metric is not sufficient. If i submit a solution with all 1 (all boundaries) recall is 1 as there are no false negatives....
@zindi team please rectify the problem.
