The V-WSP variable reduction is a MATLAB routine for calculating unsupervised variable reduction based on V-WSP algorithm. Help is provided in the wsp_reduction routine. Further info on the algorithm can be found in the following paper: D. Ballabio, V. Consonni, A. Mauri, M. Claeys-Bruno, M. Sergent, R. Todeschini. A novel variable reduction method adapted from space-filling designs. Chemometrics and Intelligent Laboratory Systems (2014), 136, 147-154. Four datasets (simulated, aphid, coffee and biodeg) are provided as example files.
Conditions and warranty
The routine is freeware and may be used (but not modified) if proper reference is given to the authors. Preferably refer to the followign papers:
