Another well thought-out Weka course from Waikato covering further areas of data mining (association rules, clustering, text classification, cost-sensitive techniques), of Weka (experimenter & knowledge flow interfaces) and of the data mining evaluation process (ROC, learning curves).
Assessments are fiddly, with a strong applied emphasis, but not too hard.
Current session closes 15/4/16, with an 'Advanced' follow-up course scheduled for late April (per Dr Witten's forum comments)
Excellent course for learning Weka. I have used it before, but was not familiar with the many meta-methods and how to use them with filters. I hope there is a folllow on to this course.
