Really pleased to see that so many good proposals have come in! And kudos to unselected applicants for taking on the challenge as well. 

And thanks to ARC for the contest. I've just spent a lot of time fumbling down (what seem to be) blind alleys, which may or may not say something about my fitness for the field, but I've also gotten my head around a few basics of modern ML in the process.

I hope the contest is achieving its goals for ARC too.
