核心知识框架

多模态融合(Week 3–4) 早期融合(特征拼接)、晚期融合(决策融合)、张量融合(TFN)、低秩多模态融合(LMF)、CLIP 对比学习。核心问题:如何在不同模态数据异质性下有效对齐表示。

大型多模态模型(Week 5) 从专用视觉-语言模型到统一多模态模型,涵盖预训练策略和 instruction tuning。

多模态推理(Week 9) 可解释推理:链式思考在多模态场景下的扩展、推理与感知的边界。

智能体(Week 12) 从工具调用到多步规划,代理系统在多模态输入环境下的构建。

自进化 AI(Week 14) 自我改进机制在多模态场景的应用,与 CS329A 的”测试时算力制造训练数据”论点高度呼应。

适合谁

  • 想系统学多模态 AI 理论(不只是用工具)的研究者和工程师
  • 需要从融合、对齐、生成到推理完整知识图的人
  • 想了解跨领域应用(制造、城市、交通)的从业者

Paul Liang 本人是 MultiBench 多模态基准的作者,这门课是他把自己的研究体系整理成教学材料的结果,比很多”调包课”有更扎实的理论深度。

Core Knowledge Framework

Multimodal Fusion (Weeks 3–4): Early fusion (feature concatenation), late fusion (decision fusion), tensor fusion (TFN), low-rank multimodal fusion (LMF), CLIP contrastive learning. The core challenge: aligning representations across modalities with different data distributions.

Large Multimodal Models (Week 5): From specialized vision-language models to unified multimodal models, covering pretraining strategies and instruction tuning.

Multimodal Reasoning (Week 9): Chain-of-thought in multimodal settings, the boundary between reasoning and perception.

Agents (Week 12): From tool-calling to multi-step planning in multimodal input environments.

Self-evolving AI (Week 14): Self-improvement mechanisms for multimodal settings — closely aligned with the CS329A thesis that “test-time compute manufactures training data.”

Who It’s For

  • Researchers and engineers who want to systematically study multimodal AI theory (not just use tools)
  • Anyone who needs a complete knowledge map from fusion and alignment through generation and reasoning to agents
  • Practitioners interested in cross-domain applications (manufacturing, urban planning, transportation)

Paul Liang is the author of MultiBench, the multimodal AI benchmark. This course is his research system organized as teaching material — with more theoretical depth than most “API-calling” AI courses.
