Struct NgramStats 

pub struct NgramStats {
    pub trigrams: HashMap<(String, String, String), (u32, u32)>,
    pub quadgrams: HashMap<(String, String, String, String), (u32, u32)>,
}

N-gram 統計（3-gram, 4-gram パターン学習）

Fields

trigrams: HashMap<(String, String, String), (u32, u32)>

3-gram: (a1, a2, a3) → (success_count, failure_count)

quadgrams: HashMap<(String, String, String, String), (u32, u32)>

4-gram: (a1, a2, a3, a4) → (success_count, failure_count)

Implementations

impl NgramStats

pub fn trigram_success_rate(&self, a1: &str, a2: &str, a3: &str) -> f64

3-gram の成功率を計算

pub fn quadgram_success_rate( &self, a1: &str, a2: &str, a3: &str, a4: &str, ) -> f64

4-gram の成功率を計算

pub fn trigram_value(&self, a1: &str, a2: &str, a3: &str) -> f64

3-gram の価値スコア [-1, 1]
