Mathematics and Statistics References:

- Introduction to Statistical Learning with Applications in R, entire text is available online, along with data sets and R code. Designed for a broader audience than Elements of Statistical Learning, but covers much the same topics . There is a MOOC for this(see below).
- Elements of Statistical Learning. Many of the same authors as above, also connected to the MOOC below, has associated R packages.
- Shape of Data, blog about the geometry and topology of data sets, providing a lot of geometric intuition for data science work.
- Advanced Data Analysis from an Elementary Point of View, a draft of a text on data analysis that assumes familiarity with stats, probability, linear algebra, calculus (uses R).
- Nice introductory and big-picture material on “Algebraic Perspective on Deep Learning” — tensor networks, algebraic descriptions of probabilistic models

Machine Learning References

- Distill is a new journal with visual easy-to-read articles about machine learning topics.
- Short science publishes summaries and reviews of research articles, mostly about machine learning and related fields.
- Nice visuals introducing machine learning from r2d3
