Webture representation into a hash code, i.e. a short binary string that can act as an index to directly access el-ements in a database, e.g. (Salakhutdinov & Hinton, 2007; Weiss et al., 2009; Kulis & Darrell, 2009). 1.2. Metric Learning Approximate nearest neighbor search in general, and hashing-based approaches in particular, provide a Webreserving Hashing is to not only preserve the neighborhood relationships, but also preserve the neighborhood rankings. As shown in Fig. 1(c), TPH ensures that H(q1) and H(q2) are neighbors of H(p), and H(q1) is still a nearer neighbor of H(p) in Hamming space. Our method can be considered as a tight version of neighborhood-preserving and a loose
