Struct hnsw::Params

pub struct Params { /* fields omitted */ }

Methods

impl Params

pub fn new() -> Self

pub fn ef_construction(self, ef_construction: usize) -> Self

This is refered to as efConstruction in the paper. This is equivalent to the ef parameter passed to nearest, but it is the ef used when inserting elements. The higher this is, the more likely the nearest neighbors in each graph level will be correct, leading to a higher recall rate and speed when calling nearest. This parameter greatly affects the speed of insertion into the HNSW.

This parameter is probably the only one that in important to tweak.

Defaults to 400 (overkill for most tasks, but only lower after profiling).
