Researchers have introduced PsiLogic, a novel optimizer designed to improve upon existing adaptive methods like Adam and AdamW. PsiLogic dynamically adjusts its update rule based on the stability of training, employing a chaos detector to enhance damping during unstable phases and fading out as training converges. This approach aims to provide an implicit warmup without manual tuning. In evaluations using the FairBench benchmark on NVIDIA H100 GPUs, PsiLogic demonstrated superior performance in three out of four tested domains, including NLP perplexity and ViT/ResNet accuracy, while maintaining comparable GPU memory usage but incurring a slight wall-clock overhead.
