WitrynaSecurity tools are an indicative example of this application of GPUs. In this paper a lightweight and efficient GPU accelerated hashing and hash lookup mechanism is presented, utilizing the CUDA General Purpose GPU (GPGPU) toolkit. The core of the system computes the digests of files using a CUDA-optimized SHA-3 hashing … Witryna1 lis 2015 · Abstract. Approximate k NN ( k -nearest neighbor) techniques using binary hash functions are among the most commonly used approaches for overcoming the prohibitive cost of performing exact k NN queries. However, the success of these techniques largely depends on their hash functions' ability to distinguish k NN items; …
Witryna10 lis 2015 · 局部敏感哈希 (Locality Sensitive Hashing，LSH)算法是我在前一段时间找工作时接触到的一种衡量文本相似度的算法。. 局部敏感哈希是近似最近邻搜索算法中最流行的一种，它有坚实的理论依据并且在高维数据空间中表现优异。. 它的主要作用就是从海量的数据中挖掘 ... In computer science, locality-sensitive hashing (LSH) is an algorithmic technique that hashes similar input items into the same "buckets" with high probability. (The number of buckets is much smaller than the universe of possible input items.) Since similar items end up in the same buckets, this technique … Zobacz więcej An LSH family $${\displaystyle {\mathcal {F}}}$$ is defined for • a metric space $${\displaystyle {\mathcal {M}}=(M,d)}$$, • a threshold $${\displaystyle R>0}$$, Zobacz więcej One of the main applications of LSH is to provide a method for efficient approximate nearest neighbor search algorithms.
