ModelInterface

class liesel.goose.ModelInterface(*args, **kwargs)

Bases: Protocol

Defines a standardized way for Goose to communicate with a statistical model.

This means predominantly, to update the model state and to compute the log-probability.

Methods

extract_position(position_keys, model_state)	Extracts the position from the model state given a sequence of position keys.
log_prob(model_state)	Computes the unnormalized log-probability given the model state.
update_state(position, model_state)	Updates the model state with the values in the position.
