The latter formula is commonly used in industrial applications including major web search companies [5] and data science competition platforms such as Kaggle. [ 6 ] These two formulations of DCG are the same when the relevance values of documents are binary ; [ 3 ] : 320 r e l i ∈ { 0 , 1 } {\displaystyle rel_{i}\in \{0,1\}} .
