treating that as the pie that you'll train in your loss function.

So we have the R of did we win or lose?

We have the pie of what was the end result of this whole expensive process.

And then at test time, we are going to do these 24,000 steps.

Every single...

every single move to pick the arg max that satisfies both exploration and exploitation.

Everyone was very excited about AlphaGo.

And at the time in what was this, 2017?

2016.

Everyone's very excited about this.

And the important thing to pick up is that we did 800 MCTS simulations and to cover 361 possible actions on average.

So that gives us about two samples roughly on an expectation for every single action.

So here you need like 2 million of them for a similar depth.

For a similar depth.

And then that's still, to do a depth of 30, I would still have to do this times 30.

This would be 60 million invocations of the model.

So that better be a small model, right?

That's a lot.

So yeah.

Yeah, so exactly, to do one action.
