Action Rules API

# Import Module
from action_rules import ActionRules

# Get Data
transactions = {'Sex': ['M', 'F', 'M', 'M', 'F', 'M', 'F'],
                'Age': ['Y', 'Y', 'O', 'Y', 'Y', 'O', 'Y'],

                'Survived': [1, 1, 0, 0, 1, 1, 0],
                }

# Print rules
# Example: [(Age: O) ∧ (Sex: M) ∧ (Embarked: S → C)] ⇒ [Survived: 0 → 1], support of undesired part: 1, confidence of undesired part: 1.0, support of desired part: 1, confidence of desired part: 1.0, uplift: 1.0
for action_rule in action_rules.get_rules().get_ar_notation():
    print(action_rule)
# Print rules (pretty notation)
# Example: If attribute 'Age' is 'O', attribute 'Sex' is 'M', attribute 'Embarked' value 'S' is changed to 'C', then 'Survived' value '0' is changed to '1 with uplift: 1.0.
for action_rule in action_rules.get_rules().get_pretty_ar_notation():
    print(action_rule)
# JSON export
print(action_rules.get_rules().get_export_notation())
