I remember reading about this on Twitter because of a reply from h2o.ai account. https://twitter.com/ppleskov/status/1215983188876709888?s=19 The person was originally employed at h2o.ai and as a consequence of this was fired. Not sure if that was completely appropriate. Wasn't this a personal participation? Or are there "company teams" on Kaggle ?

...he said, and then refreshed HN.
Propose HN: 'Countless' experiment – hiding all karmic integers : https://news.ycombinator.com/item?id=19745267 Perhaps someday we'll get a week without them.

No chance. HN’s goal is to have every effective programmer in the world checking it at least once a week. Anything that gets in the way of that is de facto bad. (I’d love to be surprised, though.) You can get the same effect with a Tampermonkey script I wrote: https://news.ycombinator.com/item?id=14456200 It even scrambles the karma count in your profile, so there’s no opportunity for karma to affect you.

#45> The goal was to create an algorithm that could predict how quickly a pet would be adopted based on its profile details, from its photo to its breed, sex, size, age, and whether it had been vaccinated or not. > These predictions would be used to optimize and tweak future critters' profiles so that they are adopted as soon as possible. Sorry but, how is this useful? You can't just change the age of an animal to make…
I'm not sure how this website manages "inventory", but they might have similar problems.

#46Am I missing something? It seems like "adoption speed" really isn't something you want to over optimize. The whole point is to match abandoned animals with suitable homes. Adoption speed seems secondary to post adoption measures of adopter satisfaction and adoptee welfare.

Also what you are writing are extremely sparse and weak signals compared to adoption speed.

Everything in moderation, right? Including games we play for imaginary Karma. I must say, though, I generally like the way HN does it. It isn't nearly as in your face and I don't find that motivates my behavior very much.
