Readable code; COBOL is easy to follow
From 2 comments
I was taken with how readable it is, personally. I'd say "like python but next level" but I know at least that much history.
klyrs on HNThis is really cool! It's great to see a simple but nontrivial program to get a feel for how a language like this works. Reading through and knowing no COBOL, it looks like this…

I think the perceptron algorithm does not include a sigmoid, just a stepwise activation. https://en.wikipedia.org/wiki/Perceptron

Code is not idiomatic COBOL

yeah, please don't take this code like is good COBOL code, haha, I learned it just for this experiment.

Questions
What do the COBOL data declarations like PIC S99V9999 mean
From 1 comment
When classifying it's often a good idea to feed the prediction into a sigmoid-function. I have never seen cobol code before, only heard about it so thanks for posting some. What…
