NJUxlj/Travel-Agent-based-on-Qwen2-RLHF
A travel agent based on Qwen2.5, fine-tuned by SFT + DPO/PPO/GRPO using traveling question-answer dataset, a mindmap can be output using the response. A RAG system is build upon the tuned qwen2, using Prompt-Template + Tool-Use + Chroma embedding database + LangChain
Implements multiple RAG strategies (naive, Self-RAG with adaptive retrieval tokens, and MemWalker with hierarchical memory trees and backtracking) selectable via dispatcher, plus a multi-agent tool system integrating Google Search, weather, hotel booking, and flight APIs with LLM-driven function calling. Supports end-to-end RLHF training across SFT, DPO, PPO, and GRPO with LiteLLM/Hugging Face trainers, and generates visual mindmaps from travel itineraries via Gradio frontend.
