以主持《宇宙：时空之旅》和《星谈》等科学节目而闻名的美国天体物理学家和科学传播者。
Topics
Neil deGrasse Tyson: 本集探讨了感知的根源、人工智能的智能性以及自由能原理。他认为物理学是所有学科的基础，神经科学也不例外。他提出了许多问题，例如大脑如何理解外部世界，以及如何将大脑的工作机制应用于机器。 Chuck Nice: 他与嘉宾Karl Friston讨论了主动推理和贝叶斯推理的概念，以及它们在认知神经科学中的作用。他还对人工智能的“幻觉”现象提出了疑问。 Gary O'Reilly: 他与嘉宾讨论了人工智能的智能性，以及人类与人工智能之间的区别。他还对人工智能的道德问题提出了担忧。 Karl Friston: 他介绍了自由能原理，这是一种描述事物自我组织方式的原则和方法。他解释了主动推理和贝叶斯推理的概念，以及它们在理解大脑运作和精神疾病中的作用。他还讨论了人工智能的局限性，以及如何将自由能原理应用于构建更可持续、更节能的人工智能系统。他认为，当前的大型语言模型虽然能够生成流畅的语言，但这并不意味着它们具有真正的理解力，并且它们在能源消耗方面也存在问题。他认为，更小、更节能的生物启发式方法更可取。 Neil deGrasse Tyson: 他强调了物理学在理解大脑运作中的重要性，并对人工智能的未来发展方向提出了思考。他认为，我们正从信息时代进入智能时代，而智能时代的一个关键问题是判断当前的生成式AI是否具有代理性。他还对人工智能获得意识并对人类做出不利于人类的决定的可能性表示担忧。

Deep Dive

Chapters
The episode begins with an introduction to the concept of the brain as a simulator of reality, drawing parallels between physics and neuroscience. The discussion introduces theoretical neuroscientist Karl Friston and his work on the free energy principle.
  • Physics principles can be borrowed by neuroscientists to understand brain function.
  • Karl Friston is a leading neuroscientist known for his work on neuroimaging and the free energy principle.
  • The free energy principle is a method to describe self-organization and adaptive behavior.

Shownotes Transcript

Are we all living in a simulation inside our brains? Neil deGrasse Tyson and co-hosts Chuck Nice and Gary O’Reilly learn about the root of perception, if AI really is intelligent, and The Free Energy Principle with theoretical neuroscientist Karl Friston.
