And before you get it, you want to predict it, again, based on your past action and observation sequence.

You just condition extra on your actions.

There's an interesting alternative that you also try to predict your own actions.

Lex Fridman Podcast
#75 โ€“ Marcus Hutter: Universal Artificial Intelligence, AIXI, and AGI

If you want.

#75 โ€“ Marcus Hutter: Universal Artificial Intelligence, AIXI, and AGI

In the past or the future?

In your future actions.

Wait, let me wrap.

I think my brain is broke.

We should maybe discuss that later after I've explained the IC model.

Exactly.

The whole history from birth sort of of the agent.

#75 โ€“ Marcus Hutter: Universal Artificial Intelligence, AIXI, and AGI

And we can come back to that also why this is important here.

Often, you know, in RL, you have MDPs, macro decision processes, which are much more limiting.

#75 โ€“ Marcus Hutter: Universal Artificial Intelligence, AIXI, and AGI

OK, so now we can predict

#75 โ€“ Marcus Hutter: Universal Artificial Intelligence, AIXI, and AGI

conditioned on actions.

#75 โ€“ Marcus Hutter: Universal Artificial Intelligence, AIXI, and AGI

So even if we influence the environment, but prediction is not all we want to do, right?

Lex Fridman Podcast
#75 โ€“ Marcus Hutter: Universal Artificial Intelligence, AIXI, and AGI

We also want to act really in the world.

Lex Fridman Podcast
#75 โ€“ Marcus Hutter: Universal Artificial Intelligence, AIXI, and AGI

And the question is how to choose the actions.

#75 โ€“ Marcus Hutter: Universal Artificial Intelligence, AIXI, and AGI
