1: Big data has a wide range and has nothing to do with machine learning algorithms. In fact, the requirements for mathematics are very low. What is really useful for big data is keen insight, and the mathematical foundation should be there. That's for sure. If it's not good, it's fine. If you study with peace of mind, you can supplement it in time, and you won't need too much mathematical knowledge than probability theory and mathematical statistics.
2. What is certain is that you can learn big data if you are not good at math. The more mathematical knowledge, the more helpful it is to learn big data. But this does not mean that people who are not good at math can't learn big data. Friends who are not good at math, when learning big data, just focus on the math knowledge used, don't worry too much!
3: Learning big data is not difficult! Poor mathematics cannot be a difficulty in learning big data. The most important thing is to choose a big data training class that suits you. Many zero-based big data students in Beida Jade Bird can learn to find a good job after five months of study!
