class liesel.goose.GibbsKernel(position_keys, transition_fn, identifier='')[source]#

Bases: ModelMixin, Kernel[Any, DefaultTransitionInfo, DefaultTuningInfo], ReprMixin

A Gibbs kernel implementing the Kernel protocol.

Methods

`end_epoch`(prng_key, kernel_state, ...)	Currently does nothing.
`end_warmup`(prng_key, kernel_state, ...)	Currently does nothing.
`init_state`(prng_key, model_state)	Initializes an (empty) kernel state.
`start_epoch`(prng_key, kernel_state, ...)	Currently does nothing.
`transition`(prng_key, kernel_state, ...)	Performs an MCMC transition.
`tune`(prng_key, kernel_state, model_state, epoch)	Currently does nothing.

Attributes

`error_book`	Maps error codes to error messages.
`identifier`	An identifier for the kernel object that is set by the EngineBuilder if it is an empty string.
`needs_history`	Is set to true if the kernel expects the history for tuning.
`position_keys`	Keys for which the kernel handles the transition.
