    pub neighbor_hits: usize,
    pub normalized_score: f32,
}

Expand description

Deterministic CPU-only hubness scoring over a set of dense embeddings.

Hubness is the tendency of a small number of vectors to appear in the k-nearest-neighbour lists of many other vectors in high-dimensional spaces. This module computes a lightweight hub score for each item given a flat slice of (id, embedding) pairs. Per-item hubness score.

Fields§

§item_id: String§neighbor_hits: usize

How many times this item appeared in another item’s top-k neighbour list.

§normalized_score: f32

neighbor_hits / max_possible_hits where max_possible_hits = n - 1. Zero when there are fewer than two items.
