North Coast Synthesis Ltd.

Your machine learning seminar

Welcome to Matthew Explains, the community where practitioners and enthusiasts explore machine learning, computer science, and mathematics in a fun and understanding-focused environment; facilitated by Matthew Skala, PhD, and North Coast Synthesis, Ltd.

Matthew Explains is not a course that goes through a textbook without applications, nor a collection of tutorials that give steps to follow without understanding. Many of our participants may be software engineers, but software engineering is not the main focus here. Instead, Matthew Explains is a computer science seminar. It's your chance to explore the latest research results, and interesting older work, in machine learning, mathematics, and computer science more generally. This is what you sign up for if you want to become confident that you actually understand how the technology works. This is material, and an experience, that you can't find on YouTube or in other sources that cater to the lowest common denominator. This is a private community for explorers.

We usually hold one session each week focused on a scientific paper of interest, with a downloadable and streamable video presentation and a discussion area for asking questions. Downloads, links to the original papers, slides, and transcripts are all provided, as well as convenience features like RSS feeds and email notifications. Your account also opens the archive of past sessions.
