Locality-sensitive hashing using Cosine Distance - 2024
Locality Sensitive Hashing (LSH) is an algorithm for searching near neighbors in high dimensional spaces. The core idea is to hash similar items into the same bucket. We will walk through the process of applying LSH for Cosine Similarity, with the help of the following plots from Benjamin Van Durme & Ashwin … Meer weergeven Let’s start with a simple example, assume that we partition each color into two categories: 1. not-so-red vs red 2. not-so-green vs green 3. not-so-blue vs blue 2 segmentation of RGBRGBcolors All the pixels are … Meer weergeven Now we extract a signature for every picture, the next job is to find how to measure the similarities between the signatures. Euclidean Distance dist(A,B)dist(A,B) and Cosine Similarity cosθcosθ. … Meer weergeven In order to find the nearest neighbors for a given picture, we can calculate the hamming distance in naive loops. The naive method … Meer weergeven As we apply kk random planes to the whole dataset, each data point generates a kk-bit vector, we call such vector as a sketch. Figure 1.
