# Criteo_x4

+ **Dataset description:**

  The Criteo dataset is a widely-used benchmark dataset for CTR prediction, which contains about one week of click-through data for display advertising. It has 13 numerical feature fields and 26 categorical feature fields. Following the setting with the [AutoInt work](https://arxiv.org/abs/1810.11921), we randomly split the data into 8:1:1 as the training set, validation set, and test set, respectively. 

  The dataset statistics are summarized as follows:

  | Dataset Split  | Total | #Train | #Validation | #Test | 
  | :--------: | :-----: |:-----: | :----------: | :----: | 
  | Criteo_x4 |  45,840,617     |   36,672,493  |   4,584,062    |  4,584,062    |    


  - Criteo_x4_001

    In this setting, we follow the winner's solution of the Criteo challenge to discretize each integer value x to ⌊log2(x)⌋, if x > 2; and x = 1 otherwise. For all categorical fields, we replace infrequent features with a default ``<OOV>`` token by setting the threshold min_category_count=10. Note that we do not follow the exact preprocessing steps in AutoInt, because this preprocessing performs much better. We fix **embedding_dim=16** as with AutoInt.
    
  - Criteo_x4_002

    In this setting, we follow the winner's solution of the Criteo challenge to discretize each integer value x to ⌊log2(x)⌋, if x > 2; and x = 1 otherwise. For all categorical fields, we replace infrequent features with a default ``<OOV>`` token by setting the threshold min_category_count=2. We fix **embedding_dim=40** in this setting.
