WebOverall, our decoding algorithm has two hyper-parameters: the match length n and the copy length k, which control how aggressively we trigger and apply the copy mechanism. 2.3 Application Scenarios Our decoding algorithm can be beneﬁcially applied to any scenarios where the generation outputs have signiﬁcant overlaps with reference documents. WebAug 6, 2024 · In my other post, I describe my algorithm as follows: My idea to solve this was that you should start with the person who has the fewest compatibilities, and match them with the person that they're connected to that has the fewest compatibilities. For example, since Joe is only connected with Jill, you should match them first.
