As a result, I recommend Weka for beginners because they can concentrate on the process of machine learning rather than the underlying theory, deep mathematical foundation, or programming aspects, which can be learned afterwards.

Is Weka any good?

Pros: Weka was the first tool I had used for Data Mining. It's a good tool with all the bare minimum functionalities for any student. It provides as a great source of learning and exploration. ... The machine learning algorithms that can be implemented with this software are also very easy to understand.

Is Weka widely used?

The WEKA website describes it uses as “…a specialist in a particular field is able to use ML to derive useful knowledge from databases that are far too large to be analysed by hand. WEKA's users are ML researchers and industrial scientists, but it is also widely used for teaching.”
