I'm far from expert on algorave so please correct me if I'm wrong, never been to one either just seen videos. But from what I gather they use Python to code, someone mentioned earlier about autechre et al. It's basically very similar to what they were doing, autchre used max/msp which is just a more visual version but still basically objective programming. It's more impressive though, and when it comes down to it in a live setting that makes it more enjoyable I imagine.
Deep learning and music or any art is an interesting area, kind of beyond the defined parameters of algorithmic generative music and into something that makes have to ask ourselves some difficult questions in the future perhaps
