Hello I was inquiring about Public score, I have significantly worked on my model and I have reduced my RMSE from 667 to 323 and my public score increased to 433, am asking am I on the right track I need to work on improving my RMSE By reducing it further to increase my rank?
RMSE is a measure of error, as your error decreases, your rank on the leaderboard increases.
