With regular knn, recall@10: ``` recall latency nDoc fanout maxConn beamWidth visited 0.771 0.13 100000 0 16 100 10 0.870 0.19 100000 10 16 100 20 0.953 0.42 100000 50 16 100 60 0.971 0.67 100000 100 16 100 110 ``` I tried the similarity threshold and its way worse. ``` recall latency nDoc resultSim travSim maxConn beamWidth visited 0.889 18.87 100000 0.89000 0.89500 16 100 6714 0.889 19.69 100000 0.89000 0.89000 16 100 10332 ``` -- This is an automated message from the Apache Git Service.
