How to increase Accuracy

#1

I have currently tried different values of parameter k and have standardized the values of both training and test data.
Howerver I cannot get accuracy over 79 while the leaderboard has submissions of over 80.
How to increase my accuracy?

79 is a very good accuracy with KNN. However if you still want to increase the accuracy of your submission than try deep learning models.

Hope this helped you :blush:
