Data Poisoning Attack: This involves inputting antagonistic training data into the classifier. The most common type of attack we observe is model skew. Attackers pollute training data in this way, making classifiers tilt to their preferences when classifying good data and bad data. The second attack we have observed in practice is feedback weaponization, which attempts to abuse the feedback mechanism to manipulate the system to misclassify good content as abuse (e.g. Competitor's content or part of retaliatory attacks).

We know that computers can be used for work, study, entertainment, etc. In addition to the necessary computer hardware, software is also needed. Usually, we call a computer with only hardware but no software "bare metal", which cannot do any meaningful work. At present, software can be divided into two categories according to its use: system software and application software. System software is a program designed for computer systems to efficiently use and manage computer software and hardware resources and support the operation of application software. Such as operating systems, programming languages and language processing programs, network system software, system service programs, etc. Among them, Windows operating system is what we often use. Application software is a variety of programs that are user-oriented and written to solve practical problems. It can be written by users themselves or purchased. For example, office XP, Photoshop, Red Alert and so on, which we often use.

At present, the biggest criticism of deliberate practice is that Erickson's evidence of deliberate practice mostly comes from activities with lower "cognitive complexity", such as chess, piano, basketball, taxi driving and spelling, but it has limited effect on activities with higher "cognitive complexity", such as sales and management. How to become an excellent sales or CEO through deliberate practice, and where to start? How? Practice what? The difference between learning activities with high cognitive complexity and low cognitive complexity is largely manifested in the amount and proportion of tacit knowledge. Tacit knowledge needs to be found in situations.
