Do the Cabbage patch .

Did the sprinkler system go off or something? no, I checked.

The sprinkler is shooting out a stream of water onto the grass.

And now, if you have this pump, it's like a great, great sprinkler.

I thought this building had a sprinkler system.

Suppose we wanted to compute the probability of C given s and r.

And we had a little... mirror disaster.

We make a choice for Cloudy, and let's say that, again, we choose Cloudy being positive.

So we walked around the backside, to see what was going on.

In likelihood weighting, we're going to be collecting samples just like before, but we're going to add a probabilistic weight to each sample.

Now we want to make a choice for Sprinkler, but we're constrained to always choose Sprinkler being positive, so we'll make that choice.

If you're ever in Kentucky, there's, you can see a movie of the flood, and they have sprinklers in the ceiling that will sprinkle on you during the flood scenes.

In this case, let's choose Sprinkler, and we look at the rows in the table for which Cloudy, the parent, is positive, and we see we should sample with probability 10 to s and 90 a s.

Cloudy tells us if it's cloudy or not outside, and that can have an effect on whether the sprinklers are turned on, and whether it's raining.
