The evaluation metric for this challenge is the Log Loss. Can you confirm the metric is : cross-entropy (loss) for the case of multi-class classification?

I also saw evaluation section of the challenge, that probabilities do not add to one: (.034 + .215 + .567) != 1

Image_ID            blast    brown    healthy
id_3zpci62t81.jpg   .034     .215      .567

@Zindi Can you confirm if we are dealing with multiclass or multilabel classification?

Thanks.

(Not Zindi, but:) The numbers in their examples are usually just to show the format. There is only ever ONE label per image (so multiclass) and you're right about the metric.
