Features

Hierarchical Proximity Graphs - Utilizes Hierarchical Navigable Small World graphs to achieve logarithmic search complexity through coarse-to-fine navigation.
Vector Indexing - Implements a high-performance indexing engine specifically designed for high-dimensional vector data and similarity search.
Vector Similarity Search - Implements algorithms and data structures for performing similarity search on high-dimensional vector embeddings.
Approximate Nearest Neighbor Search - Utilizes Hierarchical Navigable Small World graphs to trade absolute precision for significantly faster proximity lookups.
Graph - Constructs hierarchical proximity graphs by configuring link density to balance memory usage and retrieval recall.
Vector Indexing Engines - Acts as a high-performance engine for organizing vectors to enable rapid proximity queries and distance calculations.
HNSW Indexes - Provides a high-performance implementation of Hierarchical Navigable Small World (HNSW) indexes for approximate nearest neighbor search.
Incremental Vector Sync - Supports incremental index management by adding or removing elements without requiring a full rebuild.
Nearest Neighbor Searches - Implements algorithms for finding the closest vectors in high-dimensional space based on distance calculations.
Vector Distance Metrics - Provides the mathematical framework for implementing specialized similarity functions between high-dimensional vectors.
Customizable Distance Metrics - Allows the definition of custom similarity functions to adapt distance calculations to specific data requirements.
Greedy Graph Search - Implements greedy search traversal to efficiently navigate the graph layers toward the closest vector.
Header-only Libraries - Distributed as a header-only C++ library to enable compiler inlining and simplify integration.
Search Index Deletions - Allows for the removal of specific data points from the search index via unique identifiers.
Incremental Indexing Engines - Supports adding and updating vectors within the index without necessitating a full rebuild of the graph structure.
Index Persistence Utilities - Enables saving and loading the current index state to binary files for persistence across sessions.
Search Index Management - Includes tools for managing the index lifecycle, including marking elements as deleted to reclaim memory.
Dynamic Index Updating - Provides mechanisms to update index content and replace elements to ensure the dataset remains current.
Vector Databases - Provides the core indexing and retrieval layer necessary for building high-performance vector databases.
Multi-threaded Execution - Distributes independent search and indexing requests across multiple CPU cores to increase throughput.
Template-Based Metrics - Uses C++ template polymorphism to inject custom similarity functions without the overhead of virtual function calls.
AI & Machine Learning - Fast approximate nearest neighbors library
Machine Learning - Fast approximate nearest neighbor search library.
