How does it work? You submit your classifier to some server and it is run against what? The data set that determines your final score - hopefully not.
See my comment & links at the bottom of this page. For some reason HN always puts my comments near the bottom, even when they're getting many upvotes. (I'm guessing that HN has a comment-editing penalty from editing my comments too many times, but I'm not sure, or maybe it's from times I must have insulted the mods here.)
Edit:
I constantly get "submitting too fast", so I'll reply here.
Thanks for the info kefka. Yeah, I'll happily agree with that linked comment, that the childish crude moderation techniques used here have been hurting a once great community. It was the exact same scenario for me as for that guy. Seems I got rank-banned immediately after confronting dang about the trends of excessive downvoting and increasing side-project criticizing on HN.
I think it's because you don't have many upvoted comments in total (maybe?). I upvoted you here, though.)
A mod did that to you. See this: https://news.ycombinator.com/item?id=9165780
