Abstract:
Reinforcement Learning (RL) is increasingly pivotal in refining the capabilities of Large Language Models (LLMs) beyond their foundational training. This talk delves into the application of RL specifically within LLMs. We will begin by briefly covering LLM fundamentals—such as encoding, the Transformer architecture, pre-training, and instruction fine-tuning—which pave the way for RL integration. The core of the presentation will focus on RL modeling in this context, discussing key training scenarios like enhancing specific task abilities, employing Reinforcement Learning from Human Feedback (RLHF) for value alignment, and developing LLM-based agents. We will also explore the critical design of reward functions and introduce prominent RL algorithms, examining how these methods shape LLM behavior and performance.
