um the next thing was Donald Hoffman I by Donald Hoffman's first part of the theory which is typically the world looks nothing like what we experience it as that is obviously the case and the uh second half I don't follow it's a uh

depends on in which way you look at uh what he writes and and spells out so the second part to me is the thing that computers are an inadequate representation of what our brains are doing our brains are not computers they are something else and I think this uh

results from a misunderstanding of what a computer is there so he's driving the intuition here that the computer is a digital von Neumann machine similar to a PC and our brain is not organized in the same way as our personal computers are our brains are self-organizing systems

there are oscillators and they use very different ways of translating the information between the different parts and achieving coherence and so on then our digital computers are but this doesn't mean that they cannot be described as Turing machines the Turing machine is too general for

that thing basically you're looking at a finite state machine that can be used to compute representations and execute control functions and the brain is clearly in that category and what we can show mathematically is that these the different instances of that category are equivalent to each other which means

there are mappings you can take a digital computer and create a simulation of the brain a virtual brain in that digital computer that behaves in the same way in principle and also in principle vice versa so you can create a simulation of a digital computer in a brain

but it's this is much much more difficult because our brain is largely indeterministic so it's hard to get enough determinism from the brain to keep a model of a large digital computer stable in it and so we can only run relatively small

digital computers in our brain but using external tools for instance if you are allowed to use pen and paper we can use our analog or our chaotic and indeterministic brains to run pretty large simulations of digital computers but externalizing the memory and determinism

도널드 호프만의 이론과 뇌에 대한 컴퓨터 유추의 한계

호프만의 이론에 따르면 세상은 경험하는 대로 나타나지 않습니다.

연사는 호프만 이론의 두 번째 부분이 더 이해하기 어렵다고 생각합니다.

연사는 뇌와 디지털 컴퓨터의 차이가 컴퓨터 아키텍처에 대한 오해에서 비롯된 것이라고 주장합니다.

두뇌는 일반적인 컴퓨터와 달리 오실레이터와 다양한 정보 변환 방법을 갖춘 자기 조직화 시스템입니다.

두뇌와 튜링 머신: 수학적 동등성과 시뮬레이션

두뇌는 튜링 머신으로 설명할 수 있는데, 이는 두뇌가 제어 기능을 계산하고 실행할 수 있다는 의미입니다.

디지털 컴퓨터에서 뇌를 시뮬레이션할 수도 있고 그 반대로 시뮬레이션할 수도 있습니다.

뇌의 불확정적인 특성으로 인해 뇌의 대형 디지털 컴퓨터를 시뮬레이션하는 것은 어렵습니다.

펜과 종이와 같은 외부 도구는 두뇌를 사용하여 디지털 컴퓨터의 대규모 시뮬레이션을 실행하는 데 도움이 됩니다.
