After some internal discussions, we have decided to keep their submissions as they are now, since all kagglers deserve the right to compete as they wish, whether they will eventually win the competition or not. Also, since the top 2 on the leaderboard are no longer marked as out of the competition, we think it doesn't look as discouraging for new entrants as before. \r\n\r\n[/quote]\r\n\r\nThank you for your answer Wendy, though sorry to say, but it is actually not an answer at all and definitely not a correct mitigation.\r\n\r\n[/quote]\r\nI understand admins can have difficulties of removing competitors from the leaderboard before the deadline, since it may also discourage people. I just did my part of encouraging more people, by publishing my code skeleton for feature engineering plus grid search with xgboost. It can help many new comers getting into this competition. Xgboost has nice interface with scikit-learn and it has pip installation (install gcc firstly please), but no many people know it.\r\n\r\n[/quote]\r\n\r\nYou're absolutely right phunter and makes more sense of focusing to the main object.\r\nThough recall that it was 23 days ago, and we got no answer then at all.",

I believe most people here are not competing for the prize money: people who compete on Kaggle are great data scientists and they can easily make these money from their daily jobs. However, exploiting data leakage for winning is in the grey area: surely it would be a winning solution, but this winning solution would have no use for physics or to the Kaggle community (except a reminder for preventing future about data leakage). Having such winning solution may not help building individual's reputation in the data science community.\r\n\r\nExploiting the correlation as feedback to the training is not a hard secret, and I can post my experimental script using correlation anytime so everyone can jump to top 10.

I never was that kind of guy, who was ever afraid to tell his opinion or who was afraid to ask someone's help to integrate into my own knowledge fearing from other one's negative opinion (or downvotes). I always look forward and the time will tell unmercifully."
