Data structures often use hashing to allow fast insertion, lookup, and deletion. Hash tables or associative arrays convert a key (such as a string) into an index in an array, where the actual data resides. These data structures rely on handling collisions through methods like separate chaining ...
https://www.techtarget.com/searchdatamanagement/definition/hashinghashingBy Kinza YasarWhat is hashing? Hashing is the process of transforming any given key or a string of characters into another value. This is usually represented by a shorter, fixed-length value or key that represents and makes...
Locality-Sensitive Hashing (LSH) is a data-independent method that computes hashing functions aiming to map similar items to the same binary codes with high probability, facilitating efficient retrieval of nearby data points. AI generated definition based on: Medical Image Analysis, 2018 ...
Experimental results demonstrate that HF-2DLCHM performs well in terms of the above properties and outperforms some traditional hash functions and existing chaotic hash functions in these aspects. After the introduction, the remainder of this paper is structured as follows. Firstly, the definition of...
In this section, we give the details of the proposed Consensus hashing framework. A simple model associated with an efficient two-step optimization method is proposed for consensus hash functions learning. 4.1 Objective function With the definition of consensus measurement in hashing, we aim to find...

n --- the number of pairs in the hash table. Definition: The key density of a hash table is the ratio n/T. The loading density (or factor) of a hash table is =n/(s×b). Usually, n< Notations • 2 keys k 1 and k
Note that the data imbalance, different numbers of positive and negative neighbors, is observed in these datasets under the definition of semantic similarity. We evaluate the retrieval performance of generated bi- nary codes with three main metrics: mean average preci- sion (MAP), precision at ...
