Then it's worth 250,000 again.

Why are there so many wires?

In this video, we're going to put together gradient descent with our cost function, and that will give us an algorithm for

I'm very worried about the African front.

This is dummy wiring.

Especially the cable guy.

Laser cannons disconnected

This is a trip wire.

In previous videos, we talked about the gradient descent algorithm and talked about the linear regression model and the squared error cost function.

We have to figure out how to rewire the systems that we have.

Why do they do that?

Only a few hundred or thousand atoms across.

You want to be able to open it up, crack it open,

littleBits are actually pretty powerful.

I can rewire the output right here.

This is HP28. I'm on I67. I have the FBI suspect in custody along with one adult female and one child.

But, it turns out that the cost function for gradient of cost function for linear regression is always going to be a bow shaped function like this.

Well you probably imagine that the nervous system in the body is hardwired like your house.

And indeed, the popular press loves headlines like,

There's an electrical service duct right behind your drummer's riser.

We change a wire, we change John Henry.

Joey Costo.

So for example, depreciation, this was factory equipment, and it gets old as I use it, so I spread out its cost.

Now, my derivative term, d, d theta one j of theta one, when evaluated at this point, gonna look at right.

That's where the derivative is.

Have him put it on a separate line.

Must be all full of wires inside.

You'd have to worry about the amount of radiation that you were looking at.

It's much like on a jet.

Some of these cables are loose, Harry. I'm surprised you didn't notice a change in the quality of your picture.

All we gotta do is find that one little wire.

Thing's ancient. Wiring's medieval. Needs to be replaced.

Open an allagency channel with flags for immediate action on Jack Bauer.

And if you run gradient descent on a cost function like this, then gradient descent, you can show mathematically, you can find a much more direct path to the global minimum rather than taking a much more convoluted path where you're sort of trying to follow a much more complicated trajectory to get to the global minimum.
