Researchers have developed Style-Debiased DPO (SD-DPO), a novel method for updating large language models (LLMs) with new knowledge. This approach focuses on improving the accuracy of knowledge retrieval by using synthetic preference data, where the model's own incorrect responses are paired with correct ones. SD-DPO specifically addresses the issue of LLMs suppressing factually correct information that differs only in style from the desired output. Experiments show that SD-DPO is significantly more efficient than continued pretraining for knowledge updating and achieves high accuracy on benchmarks like QuALITY and AToKE. AI
