: This is a nice online book that covers linear algebra from a data
science perspective. Sections 1 and 2 are particularly relevant to this
week’s material.
- My favorite math videos of all time are 3blue1brown, and he has a
great linear algebra series: www.3blue1brown.com/?lesson=dot-products&topic=linear-algebra
the first four and the one on dot product would be great. He visualizes
the material mostly through the geometric interpretation (a matrix is a
linear transformation of space).
