Involving knowledge points monotonic vector Title The unbalanced number of an integer array arr of length n with indexes starting from 0 is defined as the number of indexes in the array sarr = sorted(arr) that satisfy the following conditions: 0 1 Here, sorted(arr) represents the array obtained by sorting the array arr. Given an […]

Elasticsearch: Multilingual vector search using the E5 embedding model
By JOSH DEVINS In this article, we will introduce multilingual vector search. We will use the Microsoft E5 multilingual embedding model, which has state-of-the-art performance in zero-shot and multilingual settings. We’ll cover how multilingual embedding works in general and how to use E5 with Elasticsearch. For more about multilingual search, read “Elasticsearch: Multilingual Semantic Search” […]
Add watermarks to WebGIS tile maps (vector tiles, raster tiles)
Watermark technology Watermark can provide strong evidence of the ownership of products receiving copyright information, and can monitor the spread of protected data, authenticate and control illegal copies, etc. It is also needed in today’s popular online maps Watermark technology protects map data. This article will introduce how to add watermarks to tile maps, including […]
Vector related functions and their implementation
Vector’s constructor We select the most commonly used ones for related introduction and implementation. vector(const allocator_type & amp; alloc=allocator_type()); The simplest vector default constructor, the formal parameter is a template reference variable, which can be any type of variable, such as int, char and other built-in types, or it can be a custom type. It […]

OpenCV+OpenCvSharp implements image feature vector extraction and similarity calculation
The image feature vector is a mathematical representation used to describe the content of the image. It can reflect the color, texture, shape and other information of the image. Image feature vectors can be used to do many things, such as image retrieval, classification, recognition, etc. This article will introduce the extraction of image feature […]
C++—data structure—array (vector)
vector container Basic concepts of vector Function: The vector data structure is very similar to an array, also known as a single-ended array The difference between vector and ordinary array: The difference is that arrays are static spaces, while vectors can be expanded dynamically Dynamic expansion: Instead of connecting the new space to the original […]
