Instances

Binary Model

mkModel :: FeatSel -> [(Xs, Ys)] -> Model

Construct model from a dataset given a feature selection function.

fromSet :: Set Feat -> Model

Construct model from a feature set. All values will be set to 1 in log domain.

fromMap :: Map Feat LogFloat -> Model

Construct model from a (feature -> value) map.

toMap :: Model -> Map Feat LogFloat

Convert model to a (feature -> value) map.

Potential

phi :: Model -> Feat -> LogFloat

Potential assigned to the feature -- exponential of the corresonding parameter.

index :: Model -> Feat -> Maybe FeatIx

Index of a feature.

onWord :: Model -> Xs -> Int -> CbIx -> LogFloat

Observation potential on a given position and a given label (identified by index).

onTransition :: Model -> Xs -> Int -> CbIx -> CbIx -> CbIx -> LogFloat

Transition potential on a given position and a given labels (identified by indexes).
