class pm4py.algo.transformation.ocel.features.events_objects.algorithm.Parameters(value)[source]

Bases: enum.Enum

An enumeration.

ENABLE_ALL_EO_FEATURES = 'enable_all_eo_features'
ENABLE_EVENT_POINTWISE_FEATURES = 'enable_event_pointwise_features'
ENABLE_PREFIX_FEATURES = 'enable_prefix_features'
pm4py.algo.transformation.ocel.features.events_objects.algorithm.apply(ocel: pm4py.objects.ocel.obj.OCEL, parameters: Optional[Dict[Any, Any]] = None)[source]

Extract features that are related to the different combinations of events and objects of the OCEL.

Parameters
  • ocel – Object-centric event log

  • parameters

    Parameters of the algorithm, including:
    • Parameters.ENABLE_ALL_EO_FEATURES => enables all the belowmentioned features

    • Parameters.ENABLE_EVENT_POINTWISE_FEATURES => enables the calculation of pointwise features for the events

    • Parameters.ENABLE_PREFIX_FEATURES => enables the prefix features

Returns

  • data – Values of the features

  • feature_names – Names of the features

class pm4py.algo.transformation.ocel.features.events_objects.prefix_features.Parameters(value)[source]

Bases: enum.Enum

An enumeration.

ENABLE_ALL_PREFIX_FEATURES = 'enable_all_prefix_features'
ENABLE_PREFIX_LENGTH = 'enable_prefix_length'
ENABLE_PREFIX_ONE_HOT_ENCODING = 'enable_prefix_1h_encoding'
ENABLE_PREFIX_TIMEDIFF = 'enable_prefix_timediff'
pm4py.algo.transformation.ocel.features.events_objects.prefix_features.apply(exploded_ocel: pm4py.objects.ocel.obj.OCEL, parameters: Optional[Dict[Any, Any]] = None)[source]

Gets some features out of the exploded OCEL which are based on the prefix of the event (for the current object)

Parameters
  • exploded_ocel – Exploded object-centric event log

  • parameters

    Parameters of the algorithm, including:
    • Parameters.ENABLE_ALL_PREFIX_FEATURES => enables the calculation of all the belowmentioned features

    • Parameters.ENABLE_PREFIX_LENGTH => adds the prefix length as a feature

    • Parameters.ENABLE_PREFIX_TIMEDIFF => adds the difference between the current event timestamp and the

      first event related to the current object.

    • Parameters.ENABLE_PREFIX_ONE_HOT_ENCODING => one-hot-encodes the activities of the prefix.

Returns

  • data – Values of the features

  • feature_names – Names of the features
