Re: Most of the classifiers in WEKA are not available

> We are trying to conduct a land cover classification of a WorldView-3 satellite image at the moment. When we open the WEKA interface, most of the classifiers are not available (please see the attached photo).

Each algorithm/filter defines what types of attributes and (if
applicable) class attributes they can process, its "capabilities". If
that set of capabilities does not match your dataset, then the
particular algorithm will be grayed out in the selection tree.
You can view the capabilities of an algorithm by selecting it (grayed
out only prevents you from running it), bringing up the details in the
GenericObjectEditor (left-click on the panel with the classifier) and
then clicking on the "Capabilities" button.
Details on the attribute types of your dataset you can see in the
Explorer's Preprocess tab.
