your discussion of precision and recall opened up a new way of thinking about accuracy to me. Kind of a weird way to learn the concept I imagine but highly appreciated nontheless

Thanks for the great post!
Could you share the code you use to calculate and plot of:
- Precision/Recall vs. Threshold plot
- Density vs. Prob inconsistent plot (with JS Divergence on top)
Thank you.

Also, I am curious if this is a typo:
Like ROC-AUC, a perfect classifier has PR-AUC = 1.0 while a random classifier has PR-AUC = 0.0
Why random classifier would have PR-AUC 0.0 instead of 0.5?

Added the code for classification metrics here
Why random classifier would have PR-AUC 0.0 instead of 0.5?
Doh, thanks for catching this. Not sure what I was thinking. It should read "a random classifier would have PR-AUC = proportion of positive labels". Thanks for catching it. Corrected!
