Unfortunately the discussion is above my current understanding. But by glancing at the comments I catched this:
remember that many people in machine learning are frequentist (or have not yet learned the Bayesian arts) and don’t really have any other means of tuning hyperparameters so they jump on whatever methods might be available.
Which explains why it's going to be so difficult for me to learn ML. It's like I'm forced to learn Aristotelian physics. Aaargh!
The relationship between F and B is not like the relationship between Aristotelian physics and relativity. Not at all.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
