Classification

Earlier, we talked about emails, spam classification as an example of a classification problem.

Here are some examples of classification problems.

lot of those assets?

Our example so far was one of classification.

linear regression for classification problems.

For classification, we know that

This is assets, of course.

We're going to consider two types of classification problems.

The second type of classification problem we'll consider will be multiclass classification problem where we may have k distinct classes.

So assets.

Total assets.

Our assets go down by 50 because I had 1,000 of assets before.

That we could create a classification of the mental illnesses.

This is one of its assets.

This was 26 billion of assets.

And maybe the assets let me just think of a good round number the assets are 10 million in assets.

That assets, A for assets, is equal to

Its assets, I divided it between 3 billion of other assets and 2 billion of CDOs.

And let's say when you liquidate the assets, there's only 8 million of assets.

So your assets will not have really changed, the absolute value of the assets.

So the total assets were 5 billion in assets.

Let's say out of this 10 million of assets, let's say that 9 million are operating assets.

Today we'll talk about classification versus regression.

So I have 1,000 of assets so essentially I'm writing down my assets by 500.

These are the assets of the company.

So it had 10 million of assets.

We control assets of over 50 billion.

That's its assets.

Other current assets.

So its assets.

These are assets.

So these are the assets of a company and it was able to generate these assets.

So what are our total assets? 4 billion plus 4 billion, it's 8 billion of assets.

Tagging is a cooperative infrastructure answer to classification.

Regression problems are fundamentally different from classification problems.

Let's say we're using the tumor classification example.

So, how do we develop a classification algorithm?

The closest classification it matches is a virus.

In HarvardYenching, it's a classification for Asian literature.

Let's just sell off all of the assets.

So expenses reduce the value of your assets.

So they stay in possession of the assets.

So they have 18 million of current assets.

So now we have 2 billion of assets.
