I gave a talk entitled Deep Learning using WebGL the 29th of October 2018 at the University of Pennsylvania. I was invited by Patrick Cozzi, who leads the development of Cesium and who have written various amazing books about WebGL and 3D programming. I explained to Master2 students in computer graphics how to use the GPU to do computations with WebGL, then how to code the specific computations required for deep learning. I detailed some tricks & tips of WebGL GPGPU.
