Cautious Weight Decay

Researchers introduced Cautious Weight Decay (CWD), a modification that applies weight decay selectively based on parameter signs, improving optimization without altering the original objective function. This technique enhances performance in language model pre-training and image classification tasks across various scales, offering content creators an easy-to-implement method to boost accuracy with existing optimizers like AdamW.
