Reading of 'The Matrix Calculus you need for Deep Learning'

I found these videos from TWIML covering the same topics

Part 1: https://www.youtube.com/watch?v=pQ5HT8LylZs&t=4s
Part 2: https://www.youtube.com/watch?v=rWRb8K-hcTo

I’ve only watched part of Part 1 but it seems to be useful…

Best regards,
Butch
