How good is a shortlist found this way
{"Image DocumentName": "How good is a shortlist found this way?", "Image ImageDescription": "We have only implemented it for a million documents with 20-bit codes --- but what could possibly go wrong? A 20-D hypercube allows us to capture enough of the similarity structure of our document set. The shortlist found using binary codes actually improves the precision-recall curves of TF-IDF. Locality sensitive hashing (the fastest other method) is 50 times slower and has worse precision-recall curves.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
