tfidf thresholds, scores from existing retrieval functions, appearance of words as anchor text, and appearance of words in the first paragraph. Loss Function The loss function used during training and evaluation is weighted subtopic loss. When evaluating a predicted subset, the penalty for not covering a particular subtopic is proportional to the total number of documents in the candidate set which covers that subtopic. This loss
