I am getting 98% accuracy in this test. However, there are many students in the leader board who got 99% accuracy. How can i improve my score?
How to improve score?
Since this is part of leaderboard challenge, you need to do this yourself. This is the only way to motivate an individual to learn more. Otherwise every student would simply ask the way as you did for the solution directly, which will not involve any learning. So try out various things hypertune the parameters, do the feature engineering and try to achieve more, 98% is itself a very good accuracy.
Hope this cleared your doubt.
