This live stream continues my series on neural networks: Matrix class improvements and the “feed forward” algorithm. I also attempt a coding challenge on image stippling / dithering.

21:11 – Improving Matrix class
55:45 – Feed Forward Neural Networks Pt.1
1:40:15 – Feed Forward Neural Networks Pt.2
