TopK Copy is a cross-attention guided copy mechanism for entity extraction where only the Top-k important attention heads are used for computing copy distributions. The motivation is that that attention heads may not equally important, and that some heads can be pruned out with a marginal decrease in overall performance. Attention probabilities produced by insignificant attention heads may be noisy. Thus, computing copy distributions without these heads could improve the model’s ability to infer the importance of each token in the input document.

Components: the archive holds no method-to-method composition, so PwC's Components table cannot be rebuilt; the Papers list carries no Results column for the same reason (the archive does not join its leaderboard rows to method tags).
