Member Data Documentation

◆ forward_pdf_class

int32 forward_pdf_class

The Pdf-classes forward-pdf-class, typically 0, 1 or 2 (the same as the HMM-state index), but may be different to enable us to hardwire sharing of state, and may be equal to kNoPdf == -1 in order to specify nonemitting states (unusual).

Definition at line 100 of file hmm-topology.h.

Referenced by kaldi::GeneratePathThroughHmm(), HmmTopology::HmmState::HmmState(), and HmmTopology::HmmState::operator==().

◆ self_loop_pdf_class

int32 self_loop_pdf_class

The Pdf-classes self-loop pdf-class, similar to Pdf-classes forward-pdf-class.

They will either both be kNoPdf, or neither be kNoPdf.

Definition at line 104 of file hmm-topology.h.

Referenced by HmmTopology::HmmState::HmmState(), and HmmTopology::HmmState::operator==().

◆ transitions

std::vector<std::pair<int32, BaseFloat> > transitions

A list of transitions, indexed by what we call a 'transition-index'.

The first member of each pair is the index of the next HmmState, and the second is the default transition probability (before training).

Definition at line 109 of file hmm-topology.h.

Referenced by TransitionModel::ComputeDerived(), kaldi::GeneratePathThroughHmm(), HmmTopology::MinLength(), and HmmTopology::HmmState::operator==().
