Mathematics for Data Science – Towards Data Science

Learning the theoretical background for data science or machine learning can be a daunting experience, as it involves multiple fields of mathematics, and a long list of online resources. In this piece, my goal is to suggest resources to build the mathematical background necessary to get up and running in data science practical/research work. These suggestions are derived from my own experience in the data science field, and following up with the latest resources suggested by the community. However, if you are a beginner in machine learning and looking to get a job in industry, I don't recommend studying all the math before starting to do actual practical work, this bottom up approach is counter-productive and you'll get discouraged, as you started with the theory (dull?) before the practice (fun!). My advice is to do it the other way around (top down approach), learn how to code, learn how to use the PyData stack (Pandas, sklearn, Keras, etc..), get your hands dirty building real world projects, use libraries documentations and YouTube/Medium tutorials.
