MAML++: Per-Layer & Per-Layer Per-Step learning rate transforms by DubiousCactus · Pull Request #328 · learnables/learn2learn

DubiousCactus · 2022-03-25T16:53:02Z

Description

Learning Per-Layer Per-Step Learning Rates (LSLR, MAML++). These GBML transforms can be used to reproduce this MAML++ functionality for MAML, MetaSGD and other algorithms which can be reproduced with GBML.
