Synopsis

Documentation

smc :: MonadDistribution m => SMCConfig m -> Sequential (Population m) a -> Population m a Source #

Sequential importance resampling. Basically an SMC template that takes a custom resampler.

smcPush :: MonadMeasure m => SMCConfig m -> Sequential (Population m) a -> Population m a Source #

Sequential Monte Carlo with multinomial resampling at each timestep. Weights are normalized at each timestep and the total weight is pushed as a score into the transformed monad.
