This is massive.

It is infinite.

Yeah.

Um, and, and so is the, uh, space of pixels, like, you know, like what can I put in an image?

I can take a picture image of anything.

Um, and so we're able to handle it.

And the same thing here where we compress from the board state, we don't represent the board state.

We compress it with a comm net.

So they have some deep.

some deep convnet that actually takes this state and converts it into a latent.

That latent compression is sufficient to do pattern matching, do some type of symmetric equivariance things.

And same thing with this and even better with JPA, which we can talk about at the end there, which is like basically taking some type of state space and doing all of our optimization in the latent space, which stable diffusion did, uh, that worked extremely well, which reduces our state space dramatically because I'm in some latent high dimensional space.

t seems to have a similar problem as before right in fact maybe even more extreme there's like infinity other variables around you right in some ways you'd think that it's this is physics newton's laws laws of motion should apply if i turn the steering wheel like this and i hit the gas i should be able to really easily model this but what is non-differentiable is that i have if i'm going into a a circle right it's like the most the biggest issue that that

we faced in when I was doing self-driving car is like, you were imposing your will onto maybe driving in India.

You're imposing your will onto the environment.

And like people just kind of adapt naturally.

Like if you were doing it in slow motion, you were going to collide.

And so that the optimal policy, if you were being strict Newtonians here would be like, don't move because anything you do, you're going to crash.

But it's not true like that.
