WebTo handle the binary constraint, in Semantic Hashing [51], the authors ﬁrst solves the relaxed problem by ignoring the binary constraints. Then, they apply thresholding on the continuous solution which results in binary codes. In Deep Hashing (DH) [47,52], the binary codes are achieved by applying the signfunction on the outputs of the last ...

WebThere are many existing encoding methods, such as Direct Encoding (DE), Histogram Encoding (HE), Unary Encoding (UE), Binary Local Hashing (BLH), etc. In this paper, use optimized unary encoding (Optimized Unary Encoding, OUE), which is an optimized scheme of binary encoding. Compared with other encoding schemes, OUE has a smaller variance. Web1.1 Locality-Sensitive Hashing for Angular Similarity For many data representations, the natural pairwise similarity is only related with the angle between the data, e.g., the normalized bag-of-words representation for documents, images, and videos, and the normalized histogram-based local features like SIFT [20]. In these cases, angular ...
