Abstract

When approximating binary similarity using the hamming distance between short binary hashes, we show that even if the similarity is symmetric, we can have shorter and more accurate hashes by using two distinct code maps. I.e. by approximating the similarity between x and x0 as the hamming distance between f 图片.png for two distinct binary codes 图片.png rather than as the hamming distance between 图片.png
