Super excited about this new work from @annhuang42.bsky.social! We developed a method for identifying different solutions to a task in neural networks of all types by walking along the flat directions of the loss landscape. Doing so revealed a ton of hidden solutions nearby in weight space!

Our new method, Hessian Null Space Continuation (HNC)! Around any trained network there is a large connected set of weights that compute nearly the same function. HNC walks through this set along flat directions of the Hessian. 1/3

Really exciting work from @annhuang42.bsky.social that was a lot of fun to be a part of! Recent work has revived the interest in finding “diverse solutions” - i.e. DNNs that perform similarly on the same task but do so with very different internal representations 1/3
