Hora 是一个近似最近邻搜索算法 (wiki) 库****Hora 完全基于 Rust🦀 实现，事实证明，Rust 确实非常非常快，完全可以媲美 C++ ，且Hora使用 SIMD进行了加速，速度非常快⚡️⚡️⚡️，具体速度可以参考下面的 benchmark.Hora ，日语为 「ほら」，读法像 [hōlə] ，意思是 Wow, You see! , Look at that! 。 这个名字的灵感来自日本著名歌曲 「小さな恋のうた」 。github： https://github.com/hora-search/hora****主页： https://horasearch.com/****Python 库： https://github.com/hora-search/horapy****Javascript 库： https://github.com/hora-search/hora-wasm**Hora 定位上是Rust实现的 ANN 算法库，希望能基于 Rust 本身的优势，能够提供多个安全的语言库，且能部署在任何地方。目前已经能在Linux**, macOS 和 Windows以及WebAssembly部署，未来还会支持Android和IOS以及 嵌入式设备*** ### Demo 这是 Hora 的在线演示（可以在这里找到它，强烈推荐试试速度！！ https://horasearch.com/)👩 Face-Match [online demo], have a try!🍷 Dream wine comments search [online demo], have a try!### benchmarkHora 非常快，bench （与 Faiss 和 Annoy 相比）### Features- Performant ⚡️ - SIMD-Accelerated (packed_simd) - Stable algorithm implementation - Multiple threads design- Supports Multiple Languages ☄️ - Python - Javascript - Java - Go (WIP) - Ruby (WIP) - Swift (WIP) - R (WIP) - Julia (WIP) - Can also be used as a service- Supports Multiple Indexes 🚀 - Hierarchical Navigable Small World Graph Index (HNSWIndex) (details) - Satellite System Graph (SSGIndex) (details) - Product Quantization Inverted File(PQIVFIndex) (details) - Random Projection Tree(RPTIndex) (LSH, WIP) - BruteForce (BruteForceIndex) (naive implementation with SIMD)- Portable 💼 - Supports WebAssembly - Supports Windows, Linux and OS X - Supports IOS and Android (WIP) - Supports no_std (WIP, partial) - No heavy dependencies, such as BLAS- Reliability 🔒 - Rust compiler secures all code - Memory managed by Rust for all language libraries such as Python's - Broad testing coverage- Supports Multiple Distances 🧮 - Dot Product Distance - - Euclidean Distance - - Manhattan Distance - - Cosine Similarity - - Productive ⭐ - Well documented - Elegant, simple and easy to learn API
