You are invited to enter the chemometrics competition. A similar competition has been a feature of the International Diffuse Reflectance Conference at Chambersburg, USA for some years.
A set of NIR spectral data is available for downloading from the ANISG website and contestants are asked to find and explain a chemometric model to robustly predict samples of the same type.
The Data
The data contains a single plant matrix FTNIR dataset containing sample_id, a spectral acquisition date, the target data (‘target_data’), the ‘set_name’ and the spectra with wavelength range from 7500 to 4000 cm-1.
The Challenge
Participants of the Panga are to build a calibration using the samples labeled as ‘calibration_set’ and predict the cases labeled as ‘test_set’ (with the ‘set_name’ column). The NIR and reference / ‘target data’ should hopefully be self explanatory to all. The date itself is also welcome to be used for modelling purposes if participants desire.
Participants will be asked to share with the conference (a couple of power point slides), the steps they took in building the calibration, and statistics of the a cross-validation of the calibration set, and prediction of the test set using their final chosen processes.
Any questions or clarifications feel free to contact Kyle at kyle.devey@hill-labs.co.nz
Happy calibration building!
