UnverifiedThe computational complexity of cross-encoders is O(n²); document representations cannot be precomputed and scoring must be done online pair by pair, so cross-encoders are typically only used to rerank the top-k results returned by an initial retrieval stage.63% similarUnverifiedCosine similarity is a symmetric metric where the similarity between A and B equals the similarity between B and A, making it unable to express the directional fulfillment relationship in resume-job matching.61% similarUnverified标准多头注意力中每个Token需与序列中所有其他Token计算相关性权重，计算复杂度为O(N²)60% similarVerifiedThe Hungarian algorithm has a time complexity of O(n³) and can find the globally optimal assignment in bipartite graph matching problems.58% similarUnverifiedCosine similarity only cares about vector direction and not length, with values strictly falling in the range [-1, 1].58% similar
