Codes for reproducing our paper "Unsupervised Feature Selection via Graph Regularized Nonnegative CP Decomposition". Specifically,
- Run the file "tensorFShandler_guan_penaltyD.m" for reproducing the results of CPUFS on the ORL dataset, and
- Run the file "tensorFShandler_chen_penaltyD.m" for reproducing the results of CPUFSnn on the same dataset.
Required packages:
- MATLAB Tensor Toolbox (downloadable from here),
- MATLAB Statistics and Machine Learning Toolbox (built-in), and
- MATLAB Parallel Computing Toolbox (built-in but non-mandatory (but one needs to change "parfor" to simple "for")).
Hope this helps. 😁
