Deep Cross-Modal Hashing with Hashing Functions and Unified Hash Codes Jointly Learning [PDF]

open access: yesarXiv, 2019
Due to their high retrieval efficiency and low storage cost, cross-modal hashing methods have attracted considerable attention. Generally, compared with shallow cross-modal hashing methods, deep cross-modal hashing methods can achieve a more satisfactory performance by integrating feature learning and hash codes optimizing into a same framework ...

A two level minimal perfect hash function for large data sets [PDF]

open access: yes
Recently several minimal perfect hashing functions far small static word sets have been developed. However, they are limited to sets of 50 words or less. In this paper, a Two Level Minimal Perfect Hash Function for large data sets is given. It partitions

ENGINEERING COMPRESSED STATIC FUNCTIONS AND MINIMAL PERFECT HASH FUNCTIONS

open access: yes, 2018
\emph{Static functions} are data structures meant to store arbitrary mappings from finite sets to integers; that is, given universe of items $U$, a set of $n \in \mathbb{N}$ pairs $(k_i,v_i)$ where $k_i \in S \subset U, |S|=n$, and $v_i \in \{0, 1, \ldots, m-1\} , m \in \mathbb{N} $, a static function will retrieve $v_i$ given $k_i$ (usually, in ...

PtrHash: Minimal Perfect Hashing at RAM Throughput [PDF]

open access: yesarXiv
Given a set $S$ of $n$ keys, a minimal perfect hash function (MPHF) is a collision-free bijective map $\mathsf{H_{mphf}}$ from $S$ to $\{0, \dots, n-1\}$. This work presents a (minimal) perfect hash function that first prioritizes query throughput, while also allowing efficient construction for $10^9$ or more elements using 2.4 bits of memory per key.
