Add new meta classifiers #209

Closed alessiobernardo closed 3 years ago

alessiobernardo commented 4 years ago

The aim of the request is to add 6 new meta classifier introduced in [1]. They are: OnlineAdaC2, OnlineBoosting, OnlineCSB2, OnlineRUSBoost, OnlineSMOTEBagging and OnlineUnderOverBagging.

I also added two other techniques called RebalanceStream [2] and CSMOTE [3].

Thanks for the pull request!

As all classifiers are for imbalanced data, please put them into a new folder "imbalanced" inside "meta", to make this clear.

Please include only java files in the pull request. Please use clear names for the classifiers, for example "OnlineBoosting.java" is too generic.

Thanks!

Hi Albert!

I added the imbalanced folder and I changed the OnlineBoosting algorithm name in OnlineAdaBoost.

Thank you!

abifet commented 3 years ago

Thanks Alessio! Can you remove all the files that are not .java in the pull request? Can you add unit tests for the new classifiers?

Thanks, Albert

Sure! I did it!
