Struct SkipChainCrf 

pub struct SkipChainCrf { /* private fields */ }

A skip-chain CRF holding the (shared) chain and skip-edge log-potentials.

Implementations

impl SkipChainCrf

pub fn new( cfg: SkipChainConfig, transition: Vec<f64>, skip_potential: Vec<f64>, ) -> SeqResult<Self>

Construct a skip-chain CRF, validating the potential shapes.

pub fn with_damping(self, damping: f64) -> SeqResult<Self>

Override the message-passing damping factor (must be in (0, 1]).

pub fn n_labels(&self) -> usize

Number of labels.

pub fn infer_marginals( &self, unary: &[f64], seq_len: usize, skip_edges: &[(usize, usize)], ) -> SeqResult<Vec<f64>>

Loopy sum-product BP returning per-position marginals (seq_len × n_labels, each position normalised to sum to 1).

pub fn infer_marginals_with_status( &self, unary: &[f64], seq_len: usize, skip_edges: &[(usize, usize)], ) -> SeqResult<(Vec<f64>, usize, bool)>

Loopy sum-product BP returning per-position marginals together with whether the message passing converged and the iteration count.

pub fn decode( &self, unary: &[f64], seq_len: usize, skip_edges: &[(usize, usize)], ) -> SeqResult<Vec<usize>>

Loopy max-product BP decoding, returning the best label per position.
