Struct IdfWeights

Source

pub struct IdfWeights { /* private fields */ }

Expand description

Pre-computed IDF weights indexed by token_id

Stored as a flat Vec<f32> for O(1) lookup by token_id. For mBERT’s 105K vocab this uses ~420KB of memory.

Implementations§

Source §

impl IdfWeights

Source

pub fn get(&self, token_id: u32) -> f32

Get the IDF weight for a token_id

Returns 1.0 for out-of-range token_ids (neutral weight).
