Hi @stark ,
In that case, considering the context, I think it should be relevant to present both IoU (IoU(c=0) and IoU(c=1)). I’m assuming that there may be some class imbalance and also that both values have different importance. I’m not sure if there’s any standard practice but you should always try to provide the relevant insight considering the context. Personally, I would report the overall IoU in a table but in the analysis I would report both to confirm that the mean is (or not) hidding any insights.
