Such methods learn hashing functions based on kernel matrixes or manifold structures and can embed the intrinsic structure in a high-dimensional space and nonlinearly map feature vectors into binary codes (Kulis and Grauman, 2012; Liu et al., 2012; Shen et al., 2015c). 4.2.3 Methodology ...
In this post, we will list out few problems that can be solved elegantly using hashing, with a significant economy of time and space. std::set, std::map, std::unordered_set, std::unordered_map in C++ HashMap, HashSet, TreeMap in Java Dictionary, Set in Python We recommend getting yo...
Also known as a hash map, the hash table is an advanced data structure that employs an associative array for storing and retrieving data via key-value pairs. The hash function processes the key to produce an index within the hash table. The system then stores the value associated with that ...
(BN)layer before each activation layer to prevent the gradient from vanishing and improve the training speed;secondly,we use Divide-and-Encode Module to map image features to approximate hash codes;finally,we adopt center loss to optimize training.Extensive experimental results on four large-scale ...
Ahashfunction can be used to map data of arbitrary size to fixed-size values. i.e.anylength ofplaintextwill result in thesamelengthhashvalue. Ahashfunction isone-way, it cannot be reversed or "un-hashed". Thehashvalueisalwaysthe same for a given string of plaintext. ...

The idea behind the string hashing is the following: we map each string into an integer and compare those instead of the strings. Doing this allows us to reduce the execution time of the string comparison to O(1) .For the conversion, we need a so-called hash function. The ...
Why is siphash even in std if HashMap has moved to libcollections? Contributor brson commented May 19, 2014 I agree with @alexcrichton that moving this hashing function into std is a step backwards (sideways maybe). Member alexcrichton commented Jun 2, 2014 Closing due to inactivity. I ...
However, there are large amounts of parameters to be trained in deep learning, and few examples are applied in online hashing at present. Among them, Online Self-Organizing Hashing [47] obtains hash codes by the Self-Organizing Map (SOM) algorithm, but SOMs with multi-layers structures have...
