Researchers have developed a new method called Duplicated Latent Residual (DLR) to improve the efficiency and quality of pre-training large language models. DLR is a training-only technique that adds a fixed structured residual to low-rank pre-training, which typically sacrifices quality for reduced parameters and computational cost. This method introduces no additional learnable parameters and can be seamlessly integrated into existing low-rank models without increasing their deployment size or computational requirements. Experiments on LLaMA models demonstrated that DLR enhances pre-training performance, particularly for models with 130 million parameters and above, and transfers effectively to downstream tasks. AI
