The evaluation metric for this competition is the mean squared error (MSE). The MSE is defined as:
\[ MSE = \sum_{i=1}^n (Z_i-Z^{\star}_i)^2 \]
where Z_i is the actual value, unknown and hosted here, Z_i* is the predicted value and i is the index.
The MSE measures the accuracy of the prediction. The lower the better!
Submission Format
submission files should contain two columns: the index of the predicted site and the predicted cobalt concentration
