and then to look at the dynamics of gradient descent and analyze gradient descent as a continuous time process and just determine what the trajectory that gradient descent follows looks like on this particular problem I can take a few more questions while people work on this one now you have guns that generate really really nice results and train on a lot of data I think like there's the vegan work presented here let's train on 27 terabytes of video so the thing I'm wondering is nobody has looked at all these videos how can you know that Yan
