Module contents#

class asterism.core.lda.GibbsLDA(n_topics=5, *, doc_size=32, vocab_size=16, dt_prior=1.0, tw_prior=1.0, desc='LDA', seed=None)#

Bases: Asterism

set_fit_request(*, display_rate: bool | None | str = '$UNCHANGED$', locs: bool | None | str = '$UNCHANGED$', n_steps: bool | None | str = '$UNCHANGED$', verbosity: bool | None | str = '$UNCHANGED$', x: bool | None | str = '$UNCHANGED$') → GibbsLDA#

Configure whether metadata should be requested to be passed to the fit method.

Note that this method is only relevant when this estimator is used as a sub-estimator within a meta-estimator and metadata routing is enabled with enable_metadata_routing=True (see sklearn.set_config()). Please check the User Guide on how the routing mechanism works.

The options for each parameter are:

  • True: metadata is requested, and passed to fit if provided. The request is ignored if metadata is not provided.

  • False: metadata is not requested and the meta-estimator will not pass it to fit.

  • None: metadata is not requested, and the meta-estimator will raise an error if the user provides it.

  • str: metadata should be passed to the meta-estimator with this given alias instead of the original name.

The default (sklearn.utils.metadata_routing.UNCHANGED) retains the existing request. This allows you to change the request for some parameters and not others.

Added in version 1.3.

Parameters#

display_ratestr, True, False, or None, default=sklearn.utils.metadata_routing.UNCHANGED
