On the use of Extendible Hashing without hashing

Information Processing Letters, 1984
On fait un rapport sur l'usage de nombres decimaux codes en EBCDIC qui sont stockes dans la table ExHash sans randomisation anterieure. Ainsi on ne distingue pas les cles des pseudocles. Ceci prevoit donc le traitement sequentiel des enregistrements dans l'ordre de cle qui est communement utilise dans les applications de base de donnee.

Hash length prediction for video hashing

2016 IEEE International Conference on Multimedia & Expo Workshops (ICMEW), 2016
Video hashing has attracted increasing attention in the field of video searching. However, there was no technical research on the prediction of hash length, which is extremely important in mobile circumstance. In this paper, a hash length prediction method is proposed for video hashing in the case of video copy detection. The video feature is mapped to

Deep Adaptively-Enhanced Hashing With Discriminative Similarity Guidance for Unsupervised Cross-Modal Retrieval

IEEE transactions on circuits and systems for video technology (Print), 2022
Cross-modal hashing that leverages hash functions to project high-dimensional data from different modalities into the compact common hamming space, has shown immeasurable potential in cross-modal retrieval.

Nonoblivious hashing

Journal of the ACM, 1988
Nonoblivious hashing, where information gathered from unsuccessful probes is used to modify subsequent probe strategy, is introduced and used to obtain the following results for static lookup on full tables: (1) An O (1)-time worst-case ...

Supervised Discrete Hashing

Computer Vision and Pattern Recognition, 2015
Recently, learning based hashing techniques have attracted broad research interests because they can support efficient storage and retrieval for high-dimensional data such as images, videos, documents, etc. However, a major difficulty of learning to hash

Load Balancing Hashing in Geographic Hash Tables

IEEE Transactions on Parallel and Distributed Systems, 2012
In this paper, we address the problem of balancing the network traffic load when the data generated in a wireless sensor network is stored on the sensor node themselves, and accessed through querying a geographic hash table. Existing approaches allow balancing network load by changing the georouting protocol used to forward queries in the geographic ...
