Nearest Neighbor

linfa-nn provides a pure Rust implementation of nearest neighbor algorithms.

The Big Picture

linfa-nn is a crate in the linfa ecosystem, an effort to create a toolkit for classical Machine Learning implemented in pure Rust, akin to Python's scikit-learn.

Nearest neighbor search (NNS), as a form of proximity search, is the optimization problem of finding the point in a given set that is closest (or most similar) to a given point. Closeness is typically expressed in terms of a dissimilarity function: the less similar the objects, the larger the function values.

Current State

linfa-nn currently provides the following implementations: - linear - balltree - KDTree
