• UM2L  This package provides an implementation of the UM2L algorithm. UM2L is a unified distance multi-metric learning approach. We implement 3 types of similarity, namely the ADS, OVS, RGS in the package.

• UMA  UMA is a package for unorganized malicious attacks detection. This package includes the MATLAB implementation of UMA, which is designed for unorganized malicious attacks detection.

• WELL This package includes the MATLAB code of the multi-label learning algorithm WELL. It tries to deal with weak label problem which is a new kind of multi-label learning problem, where only a partial label set associated with each training example is provided.

• WellSVM The package includes the MATLAB code of the algorithm WellSVM.

• WODT This package includes the Python code of Weighted Oblique Decision Trees (WODT).
