Hello @Lawrence_Moruye thanks for chearing and you did really a great work, just if this challenge was a classification one you would get a far better score in the LB, again it is clearly that this challenge need to be classification one !!

Instead of predicting the classes, I think you should try predicting the probabilities. And then, following the argmax, you mulitply the given probability by a coefficient of :

* -1 if argmax is 0

* O if argmax is 1

* 1 if argmax is 2

I think that the evaluation function (RMSE) doesn't stop us from solving this challenge as a classification problem. As long as at the end, we submit Probabilities instead of Classes/Labels.
