Struct HardNegativeMiner 

pub struct HardNegativeMiner { /* private fields */ }

Hard negative miner for selecting informative negatives

Implementations

impl HardNegativeMiner

pub fn instance_of<V: NapiRaw>(env: Env, value: V) -> Result<bool>

impl HardNegativeMiner

pub fn into_reference( val: HardNegativeMiner, env: Env, ) -> Result<Reference<HardNegativeMiner>>

pub fn into_instance(self, env: Env) -> Result<ClassInstance<HardNegativeMiner>>

impl HardNegativeMiner

pub fn new(strategy: MiningStrategy) -> Self

Create a new hard negative miner

Arguments

• strategy - Mining strategy to use

pub fn with_margin(strategy: MiningStrategy, margin: f64) -> Self

Create with margin (for semi-hard mining)

pub fn with_temperature(strategy: MiningStrategy, temperature: f64) -> Self

Create with temperature (for distance-weighted mining)

pub fn mine( &self, anchor: Float32Array, positive: Float32Array, candidates: Vec<Float32Array>, num_negatives: u32, ) -> Vec<u32>

Mine negative indices from candidates

Arguments

• anchor - Anchor embedding
• positive - Positive example embedding
• candidates - Array of candidate embeddings
• num_negatives - Number of negatives to select

Returns

Array of indices into the candidates array
