Struct RankHead

Source

pub struct RankHead { /* private fields */ }

Expand description

The classification head a reranker checkpoint carries on top of the encoder.

Implementations§

Source §

impl RankHead

Source

pub fn n_cls_out(&self) -> usize

How many floats Self::apply returns.

Source

pub fn labels(&self) -> &[String]

{arch}.classifier.output_labels, in output order. Empty for a single-output head that named none.

Source

pub fn apply(&self, pooled: &[f32]) -> Vec<f32>

Every output of the head, for pooled — which must already be the CLS row, not the whole hidden-state matrix.

Source

pub fn score(&self, pooled: &[f32]) -> f32

The single relevance score /v1/rerank reports: output 0, which is what upstream’s send_rerank sends (res->score = embd[0]).
