Binary jaccard
WebI have previously implemented Jaccard search for the binary case, where the features have been reduced to a bitstring of length 1024 bits or so. I used several papers (eg, 10.1021/ci600358f, 10.1093/comjnl/bxx046, 10.1021/ci200235e) to help get the performance. ... since Jaccard similarity is so popular for a wide number of search … WebSep 20, 2024 · BINARY JACCARD SIMILARITY (LET) BINARY ASYMMETRIC SOKAL MATCH DISSIMILARITY (LET) BINARY ASYMMETRIC SOKAL MATCH SIMILARITY (LET) BINARY ASYMMETRIC DICE MATCH DISSIMILARITY (LET) BINARY ASYMMETRIC DICE MATCH SIMILARITY (LET) YULES Q (LET) YULES Y (LET) YOUDEN INDEX …
