Taobao and Tmall Group (Xianyu) — Algorithm Research Intern (LLM/RL for pricing & social intelligence, benchmarks and offline evaluation)
RLHFInterned at Taobao and Tmall Group (Xianyu) applying LLM post-training and reinforcement learning techniques to improve real-world pricing and social intelligence systems. For pricing, you explored LLM-based reasoning over product similarities and introduced reinforcement learning to incorporate pricing knowledge, then deployed the solution for A/B testing. For negotiation/social intelligence, you built an agent and developed an internal benchmark, then iterated strategy and dialogue using hierarchical reinforcement learning to improve offline performance. • Explored LLM-based intelligent pricing strategy with reinforcement learning • Designed an internal benchmark for agent iteration and evaluation • Applied hierarchical reinforcement learning to optimize strategy and dialogue • Deployed pricing solution for A/B testing and achieved revenue gains
