Description:
P2HNNS 1.0.3
Point-to-hyperplane nearest neighbours search (P2HNNS)
A Python library for efficient Point-to-hyperplane nearest neighbours search (P2HNNS) using locality sensitive hashing (LSH) approaches.
The library implements the 5 different methods described below.
Bilinear Hyperplane (BH) hashing
Embedding Hyperplane (EH) hashing
Multilinear Hyperplane (MH) hashing
Nearest Hyperplane (NH) hashing
Furthest Hyperplane (FH) hashing
The implementation is based on the original code of HuangQiang (implemented in C++) and stepping1st(implemented in Java).
The original papers proposing each method will be explicitly provided in section Resources.
Installation
The library can be installed via the pip package manager using the following command
pip install P2HNNS
Documentation
Extensive documentation for using the library is available via Read the Docs
Tests
Unit tests are written using the pytest framework for all functionalities of the library. Tests are located in the /tests directory.
