Unsupervised Hashing with Contrastive Information Bottleneck [PDF]
Many unsupervised hashing methods are implicitly established on the idea of reconstructing the input data, which basically encourages the hashing codes to retain as much information of original data as possible.

From Image Hashing to Video Hashing [PDF]
Perceptual hashing is a technique for content identification and authentication. In this work, a frame hash based video hash construction framework is proposed. This approach reduces a video hash design to an image hash design, so that the performance of the video hash can be estimated without heavy simulation.

Performance Analysis of Sequential Cuckoo Hashing under Light of Switching Cost [PDF]
Cuckoo Hashing has been considered the state of the art since its origin. In Cuckoo Hashing, the search operation is executed sequentially in the tables, and thus, Cuckoo Hashing is Sequential Cuckoo Hashing.

We present a simple and efficient dictionary with worst case constant lookup time, equaling the theoretical performance of the classic dynamic perfect hashing scheme of Dietzfelbinger et al. (<em>Dynamic perfect hashing: Upper and lower bounds. SIAM J. Comput., 23(4):738-761, 1994</em>).

Symbolic Representation and Learning With Hyperdimensional Computing
It has been proposed that machine learning techniques can benefit from symbolic representations and reasoning systems. We describe a method in which the two can be combined in a natural and direct way by use of hyperdimensional vectors and ...

AAU-Net: Attention-Based Asymmetric U-Net for Subject-Sensitive Hashing of Remote Sensing Images
The prerequisite for the use of remote sensing images is that their security must be guaranteed. As a special subset of perceptual hashing, subject-sensitive hashing overcomes the shortcomings of the existing perceptual hashing that cannot distinguish ...

TransHash: Transformer-based Hamming Hashing for Efficient Image Retrieval [PDF]
Deep hashing has gained growing popularity in approximate nearest neighbor search for large-scale image retrieval. Until now, the deep hashing for the image retrieval community has been dominated by convolutional neural network architectures, e.g. Resnet

Algorithm of locality sensitive hashing bit selection based on feature selection
Locality sensitive hashing is one of the most popular information retrieval methods, which needs to generate long hashing bits to meet the retrieval requirement.However, a long hashing bits requires huge storage space, and contains plenty of redundant ...
