Hello,
I labeled them by hand.
They are in the resources file.
You don't need this part of the solution to get a good score.
It improves everything just a little.

Hi,julian.
How do you know or discover the "mass"feature (or other feature ) of nodule detection which improves everything just a little?
How to get this conclusion?
Thanks!

hi,julian.
Another simple question: when you submit the final_submission.csv to kaggle competition, do you keep as it is? Or change the "cancer" value to 1 if it is bigger than 0.5 and vice versa ?
Thanks!

Keep it as it is.
You can still submit to Kaggle and see the results.

I did local cross validation + cross validation against leaderboard.
BOTH needed to show improvements.
I tried around 50 features. Almost none gave consistent improvements.
Mainly due to the outlier-leaderboard but we did not know that at that time.

Hi, julian. Thank you for your reply!
I am newcomer to Kaggle. I find the public and private leaderboard, what is the outlier-leaderboard?
Thanks again.

Hi, julian. what are the 50 features? Are they the bottleneck features of the CNN network? Or some of the features are irrelevant with CNN network and are just calculated by some formulas ? Do you use some feature selection algorithms ? Maybe the combination of some features indicated by feature selection algorithm would improve the result even if each feature make a little effect. But I am not sure about that.
Thanks.
