Mathematics for Machine Learning Specialization: Formula Sheet

This is a formula sheet for "Coursera Mathematics for Machine Learning Specialization", a sequence of 3 courses on the prerequisite mathematics for applications in data science and machine learning. The specialization deals with representing data in a linear algebra context and manipulation of these objects mathematically. Summarizing the properties of data sets and mapping them onto lower-dimensional spaces with principal component analysis. Finally, solving optimization problems and using this skill to train models for describing data such as simple neural networks.
