[ANN] EmissionModels.jl: emission models for HiddenMarkovModels.jl

I’m happy to announce the first registered release of EmissionModels.jl! HiddenMarkovModels.jl is deliberately agnostic about the observation model: anything implementing rand, logdensityof, and fit! can serve as an emission model; a model specifying how observations are generated conditional on a latent state. EmissionModels.jl provides ready-to-use implementations for models that satisfy at least one of two criteria: Models commonly paired with HMMs, such as penalized generalized linear mo...
