I submitted entries for the two classification problems — “Catalysis” and “Gatineau” — in the Evaluating Predictive Uncertainty Challenge. My entry for Catalysis was the best one; my entry for Gatineau was the third best, behind two similar entries by Nitesh Chawla. The Catalysis dataset was later revealed to be about predicting a property of yeast proteins from expression levels of the genes encoding them. The nature of the Gatineau dataset has not been revealed, for proprietary reasons. The two datasets are similar in number of input variables that are available for predicting the binary outcome (617 for Catalysis, 1092 for Gatineau). They differ substantially in the number of cases available for training (1173 for Catalysis, 5176 for Gatineau) and in the fractions of cases that are in the two classes (43%/57% for Catalysis, 9%/91% for Gatineau).
