vchoice-Yc-Cats dataset
This is a variable subset choice dataset, so it consists of a collection of subset selections from varying slates of alternatives. In this dataset, the variable choice set consists of the categories of items clicked on by a user in a given browsing session on an e-commerce web site. The subset selection is the categories from which items were purchased. This dataset was derived from data for the 2015 RecSys challenge (provided by YOOCHOOSE). Some basic statistics of this dataset are:
  • number of items: 20
  • number of subset selections: 134,057
