I saw this topic in my Youtube feed (YTers are fast). Looking for a bit more info for laypeople found this[0].

Yes. This is a general improvement in a long time of the residual design in deep neural networks and it also improves on training LLMs with hyper-connections (HC) at a large scale when compared with the standard HC architecture.

So far they tested this on training 27B models with a tiny overhead and has less "exploding" signals when compared to the other approaches and the baseline. Would be interesting to see results from >100B+ parameter models.

This should be recommended reading for those interested in micro-design changes from the days of residual networks (ResNet) to Manifold-Constrained Hyper Connections (mHC).

Instead of just adding more GPUs + Money + Parameters + Data at the problem.
