Informal Starter Notebook and Video Tutorial

Informal starter notebook and video tutorial: https://www.youtube.com/watch?v=mvYLovp5isw
Extra tips:
1) I'm sorry :D
2) Think about data augmentation - is a satellite image of a road still valid upside down?
3) TTA is your friend
4) Save messing about with ensembles until you've improved everything else. Or better yet don't bother wasting compute - you can get a decent score with a single model trained for a few minutes
5) Have fun, share knowledge, enjoy the weekend <3
THANKS JOHN FOR THE TIPS AND THE NICE SAXOPHONE MELODY! :-)
Another competition and we have another great John tutorial. You are doing a tremendous job, as always.
@Amy asked me to share the actual notebook, so here you go: https://colab.research.google.com/drive/1AZCefzVBEsbNON3on7xezJvAdOQUxIwL?usp=sharing
It should score about 0.9 on the LB with plenty of room for improvement. Once again happy Friday everyone :)
