We also introduce a technique [] for training neural networks that are sparse throughout training from a random initialization - no luck required, all initialization “tickets” are winners.

Great paper title, with results to match. “MobileNets are efficient networks and difficult to sparsify. With RigL we can train 75% sparse MobileNets with almost no drop in accuracy.” 😱😱

What differs in this paper is how the connections are grown after pruning for the most important weights. I think this is part of a very interesting direction of research, amplifying the role of weights estimated to be important (in addition to removing the “weakest” links).

New work by Utku Evci et al. on sparse training. My contribution was helping with the RNN experiments. Fun collaborating with @utkuevci and getting involved in sparse man @erich_elsen's sweeping sparsity research programme.

Sparsity is a clear inductive bias for neural nets, but end to end training and efficient inference have always been a challenge. I know @erich_elsen has been thinking about this for a long time, and seems like they've made some real progress!

RigL trains sparse NNs from scratch; regularly drops the edges with the smallest magnitude, computes the gradients wrt virtual dense edges, and introduces new edges with the largest gradient. Escaping bad local minima by making a new descending direction.

Really cool improvements on Tim Dettmer's work; now sparse networks really can be trained from scratch using less GPU memory!

Well, we are back to the 2000 with the return of constructive-deconstructive methods. Glad to see this. Instead of finding the correct initialization they add and remove units according to the gradient.
