Maximum gradient

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

And essentially, the apartments cover the parking.

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

So, let's see how gradient descent works.

Sixpercent grade, fast greens, breaks to the left.

And these expressions look nasty, but what it really means is we subtract an expression like this every time we do gradient descent from W1 and an expression like this every time we do gradient descent from W0, which is easy to implement, and that implements gradient descent.

The light in this case is created through where the plasmatic magnetic field of the magnetosphere of the...

In B, it's about zero.

How can we describe this mathematically?

So at any point, the gradient is a vector.

There is no burning of the fuel in the centre of the planet.

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.

What happens?

Thrun Here is a final gradient descent quiz.

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

If we didn't have the energy from thorium, we wouldn't have carbon recycling in the crust.

Except there is a slight tether here, which keeps it from going over the top of its field.

And this is a very widespread phenomena.

If I spin this pulley, the small one's going to spin much faster.

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.

In other words, the field of the magnet is near the pigeon's head.

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.

The magnets, of course, have a magnetic field around them.

The magnetite is attracted to the earth's magnetic field.

And for the first time, we, as explained earlier, gravitational fields are created through interaction of magnetic fields.

The lines of this field run between magnetic north and magnetic south at the two poles.

And that's what it is.

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.

In a very simple way, we explain Dark Matter is actually a matter where its magnetic fields are literally in balance with the magnetic field environment of the Plasma.

What do I have?

Here is a prototypical loss function and the method for interation will be called gradient descent.

It is able to move around its environment.

It's on very steep ground.

You do this until you find yourself with what's called a local minimum, where B resides.

We already know that this has a closed form solution, but just for the fun of it, let's look at gradient descent.

Now this is really an interesting project.
