Submissions are scored on MCRMSE (mean columnwise root mean squared error):
$$
\textrm{MCRMSE} = \frac{1}{5}\sum_{j=1}^{5}\sqrt{\frac{1}{n} \sum_{i=1}^{n} (y_{ij} - \hat{y}_{ij})^2},
$$
where \\(y\\) and \\(\hat{y}\\) are the actual and predicted values, respectively.
Submission File
For each row in the dataset, the submission file should contain an identifier column (PIDN) and 5 prediction columns: Ca, P, pH, SOC, and Sand. PIDN, the sample identifier, should be copied from the first column of test data file. Ca, P, pH, SOC, and Sand are soil properties whose values you must predict.
The file should contain a header and have the following format:
PIDN,Ca,P,pH,SOC,Sand
