Mini Hack Machine Learning - Revealing your approach


I participated in the Mini Hack competition. It was my first competition on Analytics Vidhya and I earned a score of 0.692 with a leaderboard score of 76. However I want to know what other techniques did people use for getting a higher score.

For instance I ran a basic random forest model to find the feature importances and found out that Var1,var2 and Var3 have significant importances. Hence I created new polynomial variables from these 3 variables of degree 2 such as - var1var2,var2var3, var1**2 and so on…

Can someone please reveal their approaches.
