Hi — I’m Yougen Yuan. Welcome to my personal homepage. I conduct research at the intersection of LLMs/VLLMs, Agentic RAG, speech processing, multimodal learning, and clustering. This repository contains links to my projects, papers, and contact information.

• Models: Qwen, InternVL, DeepSeek, Kimi, GLM, MiniMax
• Methods: SFT, LoRA, DPO, MPO, CoT, GRPO
• Applications: RAG, Dify

• Speech Retrieval: spoken term detection, wake-up word detection, keyword spotting
• TTS: zero-shot text-to-speech, voice conversion, end-to-end spoken interaction
• ASR: automatic speech recognition
• Audio Classification: Audio scene classification, Speech language identification

• CLIP-based frameworks: weclip, youclip
• Language–image recognition, LLM-driven multimodal representation learning

• Audio, visual, and text similarity representation
• Large-scale clustering (SinglePass, HDBSCAN variants)

• Code and demo projects related to my research
• Selected models and experiments for keyword retrieval, TTS/VC, and multimodal fusion
• Notes and resources about clustering and large-scale similarity search
