Researchers have introduced "Dr. Post-Training," a novel framework that reframes general training data as a regularizer to prevent overfitting in LLMs. This approach allows for a more flexible bias-variance tradeoff compared to traditional data selection methods. Experiments across supervised fine-tuning (SFT), reinforcement learning from human feedback (RLHF), and RLVR demonstrated that Dr. Post-Training outperforms existing methods, particularly when general and target data are misaligned.
