UnverifiedThe value of K in Top-K should be determined through offline evaluation by measuring Recall@K at different K values on an annotated test set and finding the inflection point where the recall curve begins to flatten.73% similarUnverifiedThe K value for Top-K precomputation typically falls between 5 and 20, aligned with the number of suggestions displayed in the user interface, and the index size grows linearly with K.60% similarUnverifiedThe project introduces three standard retrieval evaluation metrics: Hit Rate, MRR (Mean Reciprocal Rank), and NDCG (Normalized Discounted Cumulative Gain).57% similarUnverified净 MRR 增长率 = (新增 MRR + 扩展 MRR - 流失 MRR - 收缩 MRR) / 期初 MRR57% similarUnverifiedSignTrace achieves a Mean Reciprocal Rank (MRR) of 0.9540 on the benchmark test.57% similar
