Criteo_x2

• Dataset description:

  This dataset employs the Criteo 1TB Click Logs for display advertising, which contains one month of click-through data with billions of data samples. Following the same setting with the AutoGroup work, we select "data 6-12" as the training set while using "day-13" for testing. To reduce label imbalance, we perform negative sub-sampling to keep the positive ratio roughly at 50%. It has 13 numerical feature fields and 26 categorical feature fields. In this setting, 13 numerical fields are converted into categorical values through bucketizing, while categorical features appearing less than 20 times are set as a default <OOV> feature.

  The dataset statistics are summarized as follows:

  Dataset Split	Total	#Train	#Validation	#Test
  Criteo_x2	99,616,043	86,883,012		12,733,031
