Machine learning algorithms for data mining tasks

Concretely, if you have a learning algorithm that's not performing as well as you wanted it to, how can you figure out if your learning algorithm is suffering.

Let's consider the problem of computer vision.

One final note

So, congrats on learning about your first Machine Learning algorithm.

I'll tell you a little bit about that too in this class.

And we'll begin to talk about the main types of machine learning problems and algorithms.

Andrew teaches one of the bigger Stanford classes.

Here you can see some of the inner workings, where you can see a corridor that the vehicle attempts to go.

This fall quarter, Stanford University will be offering online for free, the Machine Learning class that I teach.

What is machine learning? In this video we will try to define what it is and also try to give you a sense of when you want to use machine learning.

Welcome to the machine learning unit.

To make sense out of the data, to extract information from the data, machine learning is the discipline to go.

Most of my spam I never see, but who knows what's going to happen with the future?

So that we can get a sense of what we can expect them to do.

So congratulations.

Peter will tell you some more about machine learning.

Octave, in which you'll be able to very quickly implement the the learning algorithms we've seen already, and the learning algorithms we'll see later in this course.

There's books written about it and courses taught about it.

In the next video, we'll start to give a more formal definition of what is machine learning.

We saw that with the training set like our training set of housing prices and we feed that to our learning algorithm.

The most common prototyping language I see people use for machine

They see about 25 meters out, so to drive really fast the robot has to see further.

Given this data set, an

look at this picture it is so obvious what this is.

It's really great about the real world as we gain more data like the world wide web or medical data sets or financial data sets.

Support vector machines, a technique from machine

But perhaps the most important invention, the most important invention is machine learning.

The question is what should you then try mixing in order to improve the learning algorithm?

Sometimes learning occurs online which means while the data is being generated and some of it is offline which means learning occurs after the data has been generated.

By now, you see the range of different learning algorithms.

And having seen lots of people do this, I think you as a machine learning researcher, or machine learning developer will be much more productive if you learn to start in prototype, to start in Octave, in some other language.

This is a reasonably commonly use you type machine learning.

And it turns out in machine

Here's the definition of what is machine learning does to Arthur Samuel.

Spectral partitioning, L1 minimization. This comes from the optimization community.

Now, we've seen probabilistic word models before.

We've seen how probability theory can represent in reason with uncertainty.

It turns out the Silicon Valley, for a lot of machine learning algorithms, what we do is first prototype our software in Octave because software in Octave makes it incredibly fast to implement these learning algorithms.

It's actually quiet amazing how far technology has come in such a short amount of time.

And taking gradient descent, and the square cost function, and putting them together. That will give us our first

This is the result of computational geometry, gesture recognition, and machine learning.

Our next guest is Vukosi Marivate, who is currently a graduate student in computer science.

So, the way, of course, how we train face detectors pause that we had images where all face had been marked out.

Those pieces of junk!
