It would be interesting if you posted solutions that led you to reduce the MSE to 333333 rather than the 0 MSE one because it doesn’t provide much value for beginners. I understand that the goal of this solution is to pinpoint weaknesses of some competitions that can be “hacked” (several kaggle competitions had this) which is good for beginners but I think it would be even better to include a ML solution too.
Anyways, I was looking forward to seeing your solutions since you slayed everything and thank you for providing them, I am sure they are full of insights for aspiring AIcrew.
Have a nice day
