If I was a betting man, I’d wager the reason why they give these weirder types of challenges is because solving CAPTCHAs means you’re labelling them, which gives who ever is hosting it labelled data to train their own models against. that’s why CAPTCHAs sometimes ask ppl to spot all the zebra crossings and stuff etc - no machine can solve it yet, so ppl can do it, and by doing it and solving it, you produce a labelled dataset for autonomous cars.
- jamesy0ung 5y agoThat's how hCaptcha does it https://www.hcaptcha.com/labeling https://www.hcaptcha.com/labeling You play to get a dataset labelled and trained.
- londons_explore 5y agoExcept there are now enough labelled datasets of those things, even public freely available ones. If you wanted to increase the precision of the model further, you'd end up using very ambiguous images which wouldn't be suitable for a captcha.
- gambiting 5y agoYes, which is why every time you are given one of those captchas you deliberately pick at least one incorrect image, and it still lets you through. Back in the day when google captcha had you typing in words, it was super clear which one was generated and which one was scanned from a book or whatever - you'd always type in the scanned word completely randomly and it would still accept it.
