Concept通用训练自适应学习率衰减 / UTA LRD

UTA

A closed-loop, adaptive learning rate decay scheduling method that decomposes the learning rate curve into shape and scale and adjusts it dynamically according to training state through continuous-time modeling; it is compatible with Adam-type optimizers and is plug-and-play.
