class pm4py.algo.transformation.log_to_features.algorithm.Variants

Bases: enum.Enum

An enumeration.

Extracts the features from a log object

Parameters:

• log – Event log

• variant – Variant of the feature extraction to use: - Variants.EVENT_BASED => (default) extracts, for each trace, a list of numerical vectors containing for each

  event the corresponding features

  • Variants.TRACE_BASED => extracts for each trace a single numerical vector containing the features

    of the trace

Returns:

• data – Data to provide for decision tree learning
• feature_names – Names of the features, in order
