Researchers have introduced Aurora, a new optimizer designed to improve the training of large neural networks, particularly those with rectangular matrices. Aurora addresses issues like neuron death in MLP layers that can occur with existing optimizers like Muon, especially when row normalization is applied. By incorporating leverage-awareness and maintaining orthogonality, Aurora demonstrates significant data efficiency, achieving 100x improvement on open-source internet data and outperforming larger models on general evaluations. The optimizer is presented as a drop-in replacement with minimal overhead, and its code has been open-sourced. AI
