Struct TopKSampler

Source

pub struct TopKSampler {
    pub k: usize,
    pub temperature: f64,
    /* private fields */
}

Expand description

Zeroes out all logits except the top-k, then applies temperature sampling.

Fields§

§k: usize

Number of top tokens to keep.

§temperature: f64

Temperature applied after the top-k filter.

Implementations§

Source §

impl TopKSampler

Source

pub fn new(k: usize, temperature: f64, seed: u64) -> Result<Self, SamplingError>

Construct a TopKSampler.

Fails if k == 0 or temperature <= 0.0.

Source

pub fn sample(&mut self, logits: &[f64]) -> Result<SampledToken, SamplingError>

Sample one token from logits using the top-k filter.

Source

pub fn apply_top_k(logits: &[f64], k: usize) -> Vec<f64>

Return a copy of logits where all but the top-k entries are set to f64::NEG_INFINITY.
