File descriptions
train.csv
- The training set consists of a portion of Criteo's traffic over a period of 7 days. Each row corresponds to a display ad served by Criteo. Positive (clicked) and negatives (non-clicked) examples have both been subsampled at different rates in order to reduce the dataset size. The examples are chronologically ordered.
test.csv
- The test set is computed in the same way as the training set but for events on the day following the training period.
random_submission.csv
- A sample submission file in the correct format.
