Class 4 is now available

The six lessons for Class 4 are now available on the course website:

 

https://weka.waikato.ac.nz/

 

This class introduces some more advanced methods and techniques. The topics are:

• 4.1: Classification boundaries
• 4.2: Linear regression
• 4.3: Classification by regression
• 4.4: Logistic regression
• 4.5: Support vector machines
• 4.6: Ensemble learning

The last three are high-performance contemporary algorithms. I aim to give you a conceptual understanding of what they do and how they work, but not the gory details. You have to learn to live and work in a world where you don't understand everything. You will see some mathematics in Lessons 4.2, 4.3 and 4.5. But don't worry: I'll explain it, and anyway you don't have to fully understand the math. 

 

Next week is the last. And it's short: Class 5 has only 4 lessons, not the usual 6. And it's more relaxed: no math at all.

 

It's great to see so many people helping each other on the course forum. Please keep it up -- we greatly value your assistance.

 

By the way, we've just published a blog post about the music that accompanies the course.

 

We'll soon put out a short (optional) video to discuss a few issues that have arisen in Class 3.
