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 ...
