So it's 0 times 1, minus 1 times 1.

The Bag of Words representation is the following.

2 times negative 1.

So 1 plus 1 plus 1 plus 1 plus 1 plus 1 (let's see... that's 1, 2, 3, 4, 5, 6) plus 1 plus 1 is equal to 8.

And over here, we have nine things with a mass of one kilogram, which we could write as 1 1 1 1 1 1 1 1 1.

So the first expression is 0 and the second one is going to be 0 as well.

This map is going to produce the same result as the previous one.

1 1

1 1

I'll label it negative 1 comma negative 1.

So it's 0 times 1, which is 0.

And if we wanted to write this down as a repeated addition, well this is literally 8 ones.

Suppose we have a distribution over those cells such as this one

Let me put commas here so it doesn't look like eleven.

What's 1 2 minus 3 2?

So what's the pattern as we take the derivatives?

So we cross out row 3, column 2.

So we're going to do (1 2) first, and then subtract 3 and then subtract 4.

So I say, 80 plus 81 plus 87 plus 88.

1, 1, minus 2.

Well I get 1! This right here is 1

Then with sigma squared it's 2.

that's most of it. Here.

Choose one of the following as the correction factor.

In particular, let's start with the variance.

In the example I've chosen here are the measurements of 5., 6., 7., 9., and 10.

The answer is 2 if we multiply the data point the first expression and the second expression get 1 1 which is 1, 0, and 1 again that adds up to 2.

If you divide that by a thousand, a picometer, so a picometer is one thousand billionth of a meter, or you could say a trillionth of a meter.

And so what is that?

What is b? b is minus 1, right?

1 2 to the zero, plus 1 2, plus what's 1 2 squared?

What numbers do I have left?

So I'm gonna run out of space I'm sure.

That's not too hard.

So you cross out that row, that column.

Bravo, echo, one, one.

Some people think that instead of starting by adding 1 1, you should start with 0 and 1.

One serie, or serus, or serum? Just like the singular of sheep should be shoop.

And in this situation, this would get you, well, one half, well, 1 times one half is just one half, times one half is 1 4th, times one half is 1 8th, times one half is 1 over 16.

The ancient Egyptians used unit fractions.

And you use the same logic each to these.

Let's go through it together.

I find that amazing.

So let's just write them down in order again.

Carry the one.
