IMB-Mulan

The Mulan Framework with Multi-Label Resampling Algorithms

The Imbalanceness Mulan (IMB-Mulan) is an extension to the well-known Mulan framework (https://github.com/tsoumakas/mulan) with implementations of resampling algorithms previously proposed in the literature.

Resampling Algorithms

The following resampling algorithms were implemented in the IMB-Mulan framework:

  • Label Powerset Random Oversampling (LPROS)
  • Label Powerset Random Undersampling (LPRUS)
  • Multi-Label Random Oversampling (MLROS)
  • Multi-Label Random Undersampling (MLROS)
  • Best First Oversampling (MLBFO)
  • Multi-Label edited Nearest Neighbor (MLeNN)
  • Multi-Label Synthetic Minority Oversampling (MLSMOTE)
  • Multi-Label Resampling by Decoupling Highly Imbalanced Labels (REMEDIAL)
  • Multi-Label Resampling by Decoupling Highly Imbalanced Labels with Hybridization (REMEDIAL-HWR)
  • Multi-Label Tomek Link (MLTL)

Examples of use

The package "mulan.resampling.examples" contains codes samples explaining how to use all resampling algorithms implemented. The following code gives a brief explanation concerning the LPROS resampling algorithms.

//Creating the original dataset
MultiLabelInstances originalTrainingSet = new MultiLabelInstances(arffFilename, xmlFilename);
//Instantiate the LPROS algorithms
LPROS lpros = new LPROS(originalTrainingSet, xmlFilename);
//Resample the original training set
MultiLabelInstances resampledTrainingSet = lpros.resample();
