270 spectra in a CAL set with known concentration of a contaminant
276 spectra in a TEST set to be predicted
The goals:
Obtain the smallest RMSEP
Obtain the higher rate of good classifications;
not contaminated vs contaminated
Send the results including 2 vectors:
1. the quantification
2. the classification: 1 = contaminated 0 = clean
Send the xls file by November 30 to [email protected]
Add a DOC or PPT file with a summary of your approach
