Hi All,

I tried using xgboost with parameter tuning. However there is no change in RMSE value while submitting the solution.

Hi Surya1987,

Could you please, recheck the submission files. Please compare the both submission files before after applying the tuning parameters. May be it is due to the same submission files.

Thank you… my leadership score is unchanged while My submission score is changing. Which means I feel I am not doing proper tuning to decrease the Leaderboard score. I have to be focused on more feature training. Correct me if I am wrong.

Hi Surya1987,

does it mean that you are having good results in internal validation but when you submit, it is not improving? If it is the case then try to find good validation set.

Yes I believe. I checked another thing. I put the Value as 1 for the Outlier sales and submitted that. Still My Leaderboard score remains the same.
