Abstract:Researchers at the University of Toronto designed new algorithms to protect users’ privacy by dynamically interfering with face recognition tools. The results show that their system can reduce the proportion of face that can be detected from nearly 100% to 0.5%. On some social media platforms, every time you upload a photo or video, its […]

Recursion: The so-called recursion means that there are both transmission and regression. It is better to understand that it is a kind of “progressive” and “regular constraint” than to say that it is transmission and regression. Why do we say this? Compared with loop, recursion algorithm is more concise and clear in code structure. Recursion […]

Recently, we need to use the simple application of rectangle intersection algorithm, so we take a very simple algorithm for the novice’s reference. Why is it for the novice’s reference? Because the efficiency of this algorithm is not very high, but this algorithm only has three simple lines. The program uses two methods to judge […]

Intelligence is the ability to think rationally and control behavior. Human beings have the wisdom to think and use common sense to make decisions. Artificial intelligence is a research field of building intelligent agents, so the artificial intelligence we build in the future can think and act rationally like human beings. Turing test was proposed […]
