Maximum gradient

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

Draw scrollbar bevel

And essentially, the apartments cover the parking.

Swiss Alps Strait of Gibraltar crossing

And so, what after that?

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

Sixpercent grade, fast greens, breaks to the left.

This is a transversal line.

In B, it's about zero.

It's only half the length of this one.

I see the flags are moving out onto the track.

Even though it's a pedestrian crossing?

Coast to coast in five days.

Across the desert.

How can we describe this mathematically?

So at any point, the gradient is a vector.

Horizontal centered

Excuse me, how can you give him a ticket for jaywalking?

On a transatlantic flight?

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.

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.

I'd like to drive across the USA in a convertible car.

I'd like to drive across the USA in a convertible.

He crossed the street.

I'd like to drive across the USA in a convertible.

My father learned the magic, spent his time following light.

Hold on. Wait to cross.

You know how to cross the street.

We must do it again. Xanadiaschisoume To America.

And, you notice that my line changed a little bit.

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

But for now, using the algorithm you just learned, now we're using batch gradient descent, you now know how to implement gradient descent, or linear regression.

Adapt maximum gradient

How can we optimize these two terms over here?

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

( electric shaver buzzing ) International Airlines System Trans Polar Service flight number 102 for the Scandinavian cities in Europe now departing from Gate 88.

Be alert when you cross a busy street!

The road across the mountain was narrow, and what's more, it was a steep slope.

It makes sense because it's a downward sloping line, but it's not too steep.

The gradient with respect to W0 is very similar.

They crossed the Atlantic Ocean.

Did you get across the predestrian crossing?
