New framework enables linear merging of billion-parameter transformers

Researchers have developed a new framework for merging large pretrained transformers, specifically those with billions of parameters. This method addresses limitations of previous approaches by optimizing interpolation paths from both model endpoints simultaneously, using a dual learning procedure to align them. The technique has demonstrated near-zero loss barriers on the WikiText dataset for medium-parameter language models and maintained high accuracy on ImageNet for Vision Transformer Large models, suggesting that resolving parameter symmetries allows for reliable linear merging of large-scale transformer architectures.
