RBM emission families

HMMRBM relies on Restricted Boltzmann Machines to describe observation models. A single hidden vector per state is handled through RBMEmission, while mixtures reuse the same infrastructure with a stacked parameter representation.

API reference

HMMRBM.RBMEmissionFamily — Type

RBMEmissionFamily(rbm, l2)

Distribution family that turns hidden vectors into RBMEmission instances using the supplied RBM and regularisation coefficient.

source

HMMRBM.RBMEmission — Type

RBMEmission(rbm, hidden, l2)

Concrete emission distribution backed by an RBM and a single hidden vector. The l2 value stores the regularisation strength used during training.

source

HMMRBM.RBMMultiEmissionFamily — Type

RBMMultiEmissionFamily(rbm, l2)

Distribution family that converts stacked logits and hidden vectors into RBMMultiEmission instances.

source

HMMRBM.RBMMultiEmission — Type

RBMMultiEmission(rbm, θ, l2)

Emission distribution representing an RBM backed mixture. The stacked parameter θ contains logits and hidden vectors, while l2 records the regularisation strength.
