dataset - Letor数据集格式

Question

我刚刚发现了用于学习排序问题的 Letor 数据集。我想知道最后两列“inc”和“prob”在 train/test/vali 集中代表什么？谢谢

Answer 1

请引用Introducing LETOR 4.0 Datasets在第 2 页:如文章中所述:

Blockquote Each row is a query-document pair. The first column is relevance label of this pair, the second column is query id, the following columns are features, and the end of the row is comment about the pair, including id of the document. The larger the relevance label, the more relevant the query-document pair
