We've all been stumped by those "Captcha" puzzles. They started with single words, then pairs of words, then single images, and now, panels of images. Sometimes, it's really hard to know what the answer is. The square that contains one tiny pixel of a traffic light, is that part of the traffic light or not?
It's human versus machine. Does the machine think that pixel is part of the traffic light or not? If you get it wrong, you will be punished by another set of nine images. If you fail multiple times, you will simply be locked out of the website you wanted to visit. Woe be you!
Imagine this. We are trying to prove to a machine that we are not machines! These Captcha puzzles are explicitly designed to keep bots away. The machine will decide whether you are a human being or not.
I explain this, and a lot more in my new Fung with Data video. This journey will take you through data science, big data, machine learning, deep learning, self-driving cars, and more. These things are all inter-connected with Captchas.
