I have had images where you were teaching the neural network a wrong answer. You could see what it was they wanted me to recognize but it was wrong.

#12First, I’m going to teach you to fish. Go to hCaptcha’s website, then scroll to the footer. Click around on the about links. It’ll reveal their business model. This trick also works for other businesses and NGOs. Now, if we look at https://www.hcaptcha.com/labeling we can tell they make money by labeling data sets for a fee. So as a guess, there’s someone out there that needs to improve computer vision detection of t…
Yes but if you make a mistake the capcha fails, hence they are already labeled.

#13You're helping train self driving car models. https://www.ceros.com/inspire/originals/recaptcha-waymo-futu...
But why the boats then? Are there self rowing boats?

captchas mix classified and unclassified data.
Only if you get the classified data correct a users data is used to classify the unclassified data.
Also the same picture is shown to multiple people to improve confidence.

I would guess they have a system such that after a user has passed N captchas successfully, they trust its a human and start displaying them (a portion of) unlabelled captchas that will always succeed and that's when novel labelling happens.
Or something along those lines. And then you can get creative displaying same captcha to multiple users, etc...

Some are already labelled, the user doesn't know so it's in their interest to solve the captcha properly and provide good data.

Makes sense since other than the ones mentioned I received a lot of crosswalks, traffic lights and bicycles.

#20They might all be very relevant if the machine learning algorithm behind it decides that it needs more paper clips.
