In this video from my Machine Learning Foundations series, I’ll demonstrate matrix multiplication – the single most important and widely-used mathematical operation in machine learning. To ensure you get a solid grip on the principles of this key skill, we’ll use color diagrams, calculations by hand, interactive code demos, and an applied learning example.

There are eight subjects covered comprehensively in the ML Foundations series and this video is from the first subject, "Intro to Linear Algebra". More detail about the series and all of the associated open-source code is available at github.com/jonkrohn/ML-foundations

The next video in the series is:    • Symmetric and Identity Matrices — Topic 20...  

The playlist for the entire series is here:    • Linear Algebra for Machine Learning  

This course is a distillation of my decade-long experience working as a machine learning and deep learning scientist, including lecturing at New York University and Columbia University, and offering my deep learning curriculum at the New York City Data Science Academy.
