To all participants, it's the best time for those of us using the following features like Field_id, row_loc, col_loc and tile to contact @Zindi to remove those submissions for good leader board checking sake.
May the best model win.
Best of luck to us all.
Thanks for the headsup
I stopped preparing for this competition. Rules are too vague, and liable for inaccurate leaderboard. Good luck to all, I hope to read a summary of the winning solutions.
