This so-called hash code (or simply hash) can then be used as a way to narrow down our search when looking for the item in the map. Generally, these hash codes are used to generate an index, at which the value is stored.

WebApr 14, 2024 · How it works. A one-way hash function starts with a group of characters, called a key, which you then map onto a hash, or hash value, which is a certain length. Modern hashes are 128 bits or more; however, the hash value will be shorter than the original string of characters. The hash value is sometimes called a message digest. WebHashing has been widely researched to solve the large-scale approximate nearest neighbor search problem owing to its time and storage superiority. In recent years, a number of online hashing methods have emerged, which can update the hash functions to adapt to the new stream data and realize dynamic retrieval. However, existing online hashing methods …
