Hi to all,
Thank you again for all who participated in the ISIC 2018 challenge - we were finally able to publish our comparison to human raters where you can see how you performed with your official submissions: https://www.thelancet.com/journals/lanonc/article/PIIS1470-2045(19)30333-X/fulltext
tldr: the majority of you outperformed human experts on the target task 
(sorry for the paywall, for some reason we were not allowed to purchase open-access; we are working on a more accessible solution with a pre-print version)
