It is very important to decide what to do about the slope of the roof.

Maximum gradient

Now, they tell us what the slope of this line is.

We've also got sharpshooters securing rooftop positions.

It sends out that at local optimum your derivative would be equal to zero.

And essentially, the apartments cover the parking.

If its lower, throw up onto the roof (Japanese teeth custom)

Black roof.

On the roof! On the roof!

The roof!

He's on the roof.

And the very last one is a billboard.

So at any point, the gradient is a vector.

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

In the attic!

Sixpercent grade, fast greens, breaks to the left.

We talked about the gradient magnitude kernel, which was defined over a square root of the squares of the image gradients.

That's where the derivative is.

And it turns out there are sometimes other versions of gradient descent that are not batch versions but instead do not look at the entire traning set but look at small subsets of the training sets at the time, and we'll talk about those versions later in this course as well.

In B, it's about zero.

He's on the roof, Alan.

Up on the roof?

There goes the roof... it's all over.

100 for roofing.

I'm in the attic.

I'm up in the attic.

learning people, we're not always created has given me some algorithms.

How can we describe this mathematically?

Tom is in the attic.

So if you apply the rule over here, if you were to start at A as your W zero, then your gradient is negative.

He is on the roof.

Did you open the top?

This is what it looks like today.

Where's the top?

Luo, get on the roof.

The roof of the house is red.

The roof of my house is red.

You wake up tomorrow in a building with four floors, ten rooms.

What we're going to do is apply gradient descent to minimize our squared error cost function.

Tom is on the roof.

All the power comes from the sun.

The attics are dreadful!

Attic space. He must have been hiding.

Good idea. Good call. On the roof.
