AI的生成原理或可揭示大脑认知机制，值得神经科学借鉴。
From generative AI to the brain: five takeaways
- 从生成式AI中提炼出五种可应用于脑科学的通用原理。
- 指出世界建模、注意力等机制对理解神经信息处理有启发意义。
- 适合关注脑科学与机器学习交叉研究的学者参考。
生成式AI的突破并非源于晦涩算法，而是基于清晰的生成原则，其具体实现已在众多应用中得到验证。我们建议应深入探究这些生成原则是否也存在于大脑中，从而为认知神经科学提供新视角。此外，机器学习研究提供了对神经信息处理系统的若干有趣刻画。本文讨论了五个典型案例：世界建模的局限性、思维过程的生成、注意力机制、神经网络的缩放定律以及量化，说明神经科学可能从机器学习研究中获得重要启示。
原文摘要 · Abstract (English)
The big strides seen in generative AI are not based on somewhat obscure algorithms, but due to clearly defined generative principles. The resulting concrete implementations have proven themselves in large numbers of applications. We suggest that it is imperative to thoroughly investigate which of these generative principles may be operative also in the brain, and hence relevant for cognitive neuroscience. In addition, ML research led to a range of interesting characterizations of neural information processing systems. We discuss five examples, the shortcomings of world modelling, the generation of thought processes, attention, neural scaling laws, and quantization, that illustrate how much neuroscience could potentially learn from ML research.
