#75 – Marcus Hutter: Universal Artificial Intelligence, AIXI, and AGI

It needs to prove by itself that this change of program still satisfies the original specification.

#75 – Marcus Hutter: Universal Artificial Intelligence, AIXI, and AGI

And if it does so, then it replaces the original program by the improved program.

#75 – Marcus Hutter: Universal Artificial Intelligence, AIXI, and AGI

And by definition, it does the same job, but just faster.

#75 – Marcus Hutter: Universal Artificial Intelligence, AIXI, and AGI

And then it proves over it and over it.

#75 – Marcus Hutter: Universal Artificial Intelligence, AIXI, and AGI

And it's developed in a way that

#75 – Marcus Hutter: Universal Artificial Intelligence, AIXI, and AGI

all parts of this GΓΆdel machine can self-improve, but it stays provably consistent with the original specification.

So from this perspective, it has nothing to do with ICSI, but if you would now put ICSI as the starting axioms in,

Lex Fridman Podcast
#75 – Marcus Hutter: Universal Artificial Intelligence, AIXI, and AGI

It would run ICSI, but that takes forever.

Lex Fridman Podcast
#75 – Marcus Hutter: Universal Artificial Intelligence, AIXI, and AGI

But then if it finds a provable speedup of ICSI, it would replace it by this and this and this.

#75 – Marcus Hutter: Universal Artificial Intelligence, AIXI, and AGI

And maybe eventually it comes up with a model which is still the ICSI model.

Lex Fridman Podcast
#75 – Marcus Hutter: Universal Artificial Intelligence, AIXI, and AGI

It cannot be.

Lex Fridman Podcast
#75 – Marcus Hutter: Universal Artificial Intelligence, AIXI, and AGI

I mean, just for the knowledgeable reader, ICSI is a computable.

Lex Fridman Podcast
#75 – Marcus Hutter: Universal Artificial Intelligence, AIXI, and AGI

And I can prove that.

Lex Fridman Podcast
#75 – Marcus Hutter: Universal Artificial Intelligence, AIXI, and AGI

Therefore, there cannot be a computable exact

#75 – Marcus Hutter: Universal Artificial Intelligence, AIXI, and AGI

algorithm computers, there needs to be some approximations.

Lex Fridman Podcast
#75 – Marcus Hutter: Universal Artificial Intelligence, AIXI, and AGI

And this is not dealt with the GΓΆdel machine, so you have to do something about it.

Lex Fridman Podcast
#75 – Marcus Hutter: Universal Artificial Intelligence, AIXI, and AGI

But there's the ICSI TL model, which is finitely computable, which we could put in.

Lex Fridman Podcast
#75 – Marcus Hutter: Universal Artificial Intelligence, AIXI, and AGI

Which part of ICSI is non-computable?

#75 – Marcus Hutter: Universal Artificial Intelligence, AIXI, and AGI

The Solomonov induction part.

The induction.
