	 		       version June 25, 2010
------------------------------------------------------------------------------------------

The package includes the MATLAB code of the multi-label learning algorithm WELL, which solves the multi-label problem under weak label assumption [1].

Note that to solve the QP optimization problem we use Mosek optimization tool which can be downloaded from "http://www.mosek.com/".



For WELL, you can call the "call_WELL" function to run the transductive algorithm.

You will find an example of using this code in the example directory. The example data is Yeast. You can call function "main" to run it.
