How To Install python3-pynndescent on Debian 12
Introduction
In this tutorial we learn how to install python3-pynndescent on Debian 12.
What is python3-pynndescent
python3-pynndescent is:
PyNNDescent is a Python nearest neighbor descent for approximate nearest neighbors. It provides a Python implementation of Nearest Neighbor Descent for k-neighbor-graph construction and approximate nearest neighbor search, as per the paper:
Dong, Wei, Charikar Moses, and Kai Li. “Efficient k-nearest neighbor graph construction for generic similarity measures.” Proceedings of the 20th international conference on World wide web. ACM, 2011.
This library supplements that approach with the use of random projection trees for initialisation. This can be particularly useful for the metrics that are amenable to such approaches (euclidean, minkowski, angular, cosine, etc.). Graph diversification is also performed, pruning the longest edges of any triangles in the graph.
Currently this library targets relatively high accuracy (80%-100% accuracy rate) approximate nearest neighbor searches.
