Can you help me beat people using Python to make predictions?

Hello, 

I participated firm's challenge. I currently got an F1 score of 0.74. The highest is 0.78.

If I remove the yellow highlighted below, my score dropped to 0.73.  

If you have time, do you mind looking at my workflow?

Any advice would be greatly appreciated. 

Trigger warning: big data is coming up!

I believe I am the only one who uses Alteryx.  

Can you help me beat people using Python to make predictions?

Thank you very much for your help.
