Struct Bleu 

pub struct Bleu { /* private fields */ }

BLEU 评测器(默认 BLEU-4)。

Implementations

impl Bleu

pub fn new() -> Self

pub fn with_max_n(self, n: usize) -> Self

使用 BLEU-n(默认 4)

pub fn with_char_level(self, v: bool) -> Self

字符级分词:中文等无空格语言按字符切(否则整句成一个 token,BLEU 失效)

pub fn with_smoothing(self, v: bool) -> Self

开启平滑:某阶 n-gram 无匹配时给小值而非整体归零,短句不被一刀切

Trait Implementations

impl Default for Bleu

fn default() -> Self

Returns the “default value” for a type.

impl Evaluator for Bleu

fn eval<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, _input: &'life1 str, prediction: &'life2 str, reference: &'life3 str, ) -> Pin<Box<dyn Future<Output = Result<Score, EvalError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

对单条预测打分
