At some point, every aspiring data scientist has to get familiar with mathematics for machine learning. To be blunt, the more serious you are about data science, the more math you'll need to learn for machine learning. If you have a strong math background, this is likely to little issue. In my case, I've had to relearn much of the mathematics (note – I'm not done yet!) that I took at a university as my professional life had allowed my math skills to atrophy. Based on my experience teaching our bootcamp there is also a group of aspiring data scientists that fall into a category where their formal math training needs to be augmented.
