Revisiting the Adam-SGD Gap in LLM Pre-Training: The Role of Large Effective Learning Rates
New research explores methods to improve Large Language Model (LLM) training efficiency and effectiveness. One study challenges the necessity of a strong teacher model in knowledge distillation, finding that even smaller teachers can benefit larger students with proper loss mixing. Another paper introduces "Introspective Training" (IXT), which uses feedback-conditioned data to improve scaling and performance across all LLM training stages, leading to significant compute efficiency gains. Additionally, research on optimizers suggests that stabilizing Stochastic Gradient Descent (SGD) with clipping mechanisms can help it achieve performance comparable to adaptive optimizers like Adam in LLM pre-training.
