As we talked about, a hash work lies at the core of a hashing algorithm. The hash value is calculated after the data is partitioned into different blocks. This is on the grounds that a hash function takes in in

,xn}⊂Rd×n (denoted as the blue points in Fig. 7). For the image xi⊂Rd×1, its feature space can be split by a set of hashing functions H={h1,h2,…hK}⊂Rd×K, and each hashing function encodes xi into one bit of binary code hk(xi). Therefore, the corresponding K ...

To compensate this drawback, learning-based approaches propose to explore local data structure and/or supervised information for boosting hashing performance. However, due to the construction of Laplacian matrix, existing methods usually suffer from the unaffordable training cost. In this paper, we ...
