What are the main application scenarios of vector databases?

Vector databases are specialized databases designed to store, index, and query high-dimensional vector data efficiently. Their main application scenarios include:

  1. Semantic Search and Recommendation Systems

    • Vector databases enable fast similarity searches for unstructured data like text, images, or audio by converting them into vector embeddings.
    • Example: An e-commerce platform uses vector search to recommend products based on user preferences by comparing product descriptions or images with user behavior vectors.
  2. Computer Vision and Image Recognition

    • Storing and retrieving image embeddings for tasks like facial recognition, object detection, or visual search.
    • Example: A security system uses vector databases to match surveillance footage with known faces by comparing facial feature vectors.
  3. Natural Language Processing (NLP)

    • Efficiently searching and retrieving text documents, chatbot responses, or knowledge graphs using semantic similarity.
    • Example: A customer support chatbot retrieves relevant answers from a knowledge base by matching user queries with stored text embeddings.
  4. Multimodal AI Applications

    • Combining text, images, and audio data in AI models by leveraging vector similarity for cross-modal retrieval.
    • Example: A virtual assistant finds relevant images or videos based on a text description by comparing embeddings across modalities.
  5. Fraud Detection and Anomaly Identification

    • Detecting unusual patterns in high-dimensional data, such as transaction behaviors or network traffic.
    • Example: A financial institution uses vector databases to identify fraudulent transactions by comparing transaction vectors with normal behavior patterns.
