This article explains the principle of vector embeddings, shows how they turn words, images, audio and other data into dense numeric vectors, compares them with one‑hot encoding, describes static and contextual models, training methods, similarity metrics, and a wide range of real‑world AI applications.
AI applications rely on vector embeddings for search and recommendation, but these rich vectors expose new security and privacy threats; this article explains the main risks, attack methods, and mature MySQL strategies—including secure storage, access control, encryption, auditing, and compliance—to protect vector data.
This article explores the three stages of AI knowledge representation—vector embeddings, graph‑based structures, and the emerging hybrid approach that combines vectors, graphs, and large language models—to illustrate how modern Retrieval‑Augmented Generation systems achieve both semantic similarity and precise relational reasoning.
This article walks through the complete design and implementation of a locally deployed, enterprise‑level semantic search system using Ollama for embedding generation and Easysearch for vector retrieval, covering problem analysis, architecture decisions, pipeline configuration, bulk indexing, and hybrid query execution.
This article explains how Cursor creates Merkle‑tree hashes for change detection, uses Tree‑sitter for syntax‑aware code chunking, generates vector embeddings stored in Turbopuffer, and employs privacy‑preserving mechanisms to enable fast, secure code‑base search and autocomplete.
This tutorial explains why a personal knowledge base is essential, then walks you through installing Cherry Studio, configuring DeepSeek chat and embedding models, creating and populating the knowledge base, and finally using an AI assistant to retrieve information efficiently.
This article describes how NetEase Yanxuan has designed, trained, and deployed a unified vector representation system to power various e‑commerce search and recommendation scenarios, covering model choices, incremental learning strategies, large‑scale similarity computation, and practical lessons from real‑world deployments.
This article explains how Yanxuan built a comprehensive vector system—from product embeddings and graph models to large‑scale similarity computation—and applied it across search, recommendation, and purchase prediction tasks, highlighting practical algorithms, infrastructure, and future directions.
