LO: Compute-Efficient Meta-Generalization of Learned Optimizers
Benjamin Thérien, Charles-Ãtienne Joseph, Boris Knyazev +3
Learned optimizers (LOs) have the potential to significantly reduce the wall-clock training time of neural networks. However, they can struggle to optimize unseen tasks (meta-gener…
