View Full Version : Weka - where to start?

02-18-2008, 12:09 PM

What exactly is weka? Or; more relevant to my requirements, can it analyse a stream of data and find patterns and/or trends? If so how do i do that, which bit of the tool etc? Experimenter? Explorer? Eh?

If so how do you start? I can find very little documentation, and there's no quick start guide. Is it the sort of tool you can just throw some data into and see what comes out?

I want to be able to get my head around what it is and what it can do... I can see it's updated fairly often, but the lack of posts in here imply to me that it's rarely used?

Hi Dan,

Weka is a workbench of machine learning/data mining algorithms + GUIs. It can be used to find predictive patterns in data (i.e. mappings between input fields and a target field of interest) and for clustering (i.e. segmenting data into "natural" groups).

Machine learning/data mining is an advanced area of analytics. It is usually not the case that a point-and-click/throw some data at the problem type of approach will yield good results. If you are new to data mining and Weka, I'd suggest taking a look at the book that was written by a professor and a senior lecturer from University of Waikato to accompany the Weka software:

Ian H. Witten and Eibe Frank. 2005. Data Mining: Practical Machine Learning Tools and Techniques. Morgan Kaufmann.


There is documentation on Weka (including its various user interfaces) available both online and included (in pdf form) in the Weka distribution when you download it. See:
