Performance Optimization Techniques

Learn about HNSW, a popular indexing method used in vector databases for efficient search.

We'll cover the following
  • The challenge of searching through large datasets
  • Indexing for faster searches
    • Hierarchical navigable small world (HNSW) graph
      • Navigable small world graph (NSW)
        • Building NSW graphs
        • Performing ANN search with NSW graphs
      • Skip lists
        • Search operation in a skip list
        • Insert operation in a skip list
        • Delete operation in a skip list
        • Benefits of skip lists
    • Integrating multi-level navigation from skip lists into NSW
  • Challenges of high-dimensional data
  • Data compression and dimensionality reduction
    • Product quantization (PQ)
    • Principal component analysis (PCA)
