Struct IbmModel1 

pub struct IbmModel1 {
    pub t_fe: Array2<f64>,
    pub t_0e: Array1<f64>,
}

IBM Model 1.

Fields

t_fe: Array2<f64>

Translation probability from source word f to target word e. t_fe[(f, e)] = Pr(e|f) Shape: (|source_vocab|, |target_vocab|)

t_0e: Array1<f64>

Translation probability from null word to target word e. t_e0[e] = Pr(e|NULL) Shape: (|target_vocab|,)

Implementations

impl IbmModel1

Trait Implementations

impl Debug for IbmModel1

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Model for IbmModel1

File format

• f_size: u32
• e_size: u32
• t_fe: [f64; f_size * e_size]
• t_0e: [f64; e_size]

All values are of little endian. t_fe and t_0e are stored in row-major ascending order.

• t_fe: [(0, 0)], [(0, 1)]..., [(0, el-1)], [(1, 0)], ...
• t_0e: [0], [1], ...

fn save_to_path(&self, path: impl AsRef<Path>) -> Result<()>

Saves things into file specified as a path.
