ucam::hifst::SparseWeightVectorLatticesTask< Data, Arc > Class Template Reference

Creates lattices using tropical tuple weight semiring – each arc containing separate feature weight contributions. Note that the semiring is tropical under dot product of all these features with its scales. More...

Detailed Description

template<class Data, class Arc>
class ucam::hifst::SparseWeightVectorLatticesTask< Data, Arc >

Creates lattices using tropical tuple weight semiring – each arc containing separate feature weight contributions. Note that the semiring is tropical under dot product of all these features with its scales.

Member Function Documentation

template<class Data , class Arc >

bool ucam::hifst::SparseWeightVectorLatticesTask< Data, Arc >::run ( Data &  d )

inlinevirtual

Implements virtual method from ucam::util::TaskInterface.

Remarks

Takes an alignment lattice, maps to tuplearc32 and composes it with the grammar flower lattice. After projecting on the words (thus deleting rules), we have a word lattice containing independent feature contributions to weight in each arc.

Parameters

d	Data object

Implements ucam::util::TaskInterface< Data >.
