AI为啥不懂物理世界？李飞飞、杨立昆：缺个「世界模型」，得学大脑新皮质工作

Core Insights - The future of AI may be linked to understanding the evolutionary secrets of the human brain, as highlighted by recent developments in the AI field, including Yann LeCun's plans to establish a new AI company focused on "World Models" [1] - Fei-Fei Li emphasizes the limitations of current large language models (LLMs) and advocates for the development of "Spatial Intelligence" as a crucial step towards achieving Artificial General Intelligence (AGI) [3][4] Summary by Sections World Models - "World Models" are essential for AI to understand and predict real-world scenarios, which current AI systems struggle with, such as generating realistic videos or performing household tasks [5][6] - The concept of "World Models" arises from reflections on the limitations of LLMs and the exploration of animal intelligence, suggesting that the ability to learn these models is what current AI lacks [8] Human Perception and Intelligence - Max Bennett's research identifies three key attributes of human perception that are crucial for understanding intelligence: filling-in, sequentiality, and irrepressibility [11] - The brain's ability to fill in gaps in perception and to focus on one interpretation at a time is fundamental to how humans process information [12][20][23] Generative Models - The "Helmholtz Machine" concept illustrates how generative models can learn to recognize and generate data without being explicitly told the correct answers, demonstrating the brain's inferential processes [27] - Modern generative models, including deep fakes and AI-generated art, validate Helmholtz's theories and show that the brain's neocortex operates similarly [28] Advanced Cognitive Abilities - The neocortex not only facilitates imagination and prediction but also enables complex behaviors such as planning, episodic memory, and causal reasoning, which are desired traits for future AI systems [33] - Bennett's book, "A Brief History of Intelligence," connects neuroscience with AI, outlining the evolutionary milestones of the brain and their implications for AI development [35][37]
