Two Extractly same rules by RulefitClassifier

[Yannahhh]

Hello~

When I use the RulefitClassifier, it will return two exactly same rules but with different coef, whether the inherent structures didn't aggregate the rules? I have tried to use the Rulefit directly, and it seems that it doesn't have the similar problem~

The following image is part of my result

Hi, thanks for bringing this to our attention. Can you provide more details on the code used to produce this result?

Thanks for your reply, should I provide my data also?

features = X.columns
X = X.values
rulefit = RuleFitClassifier(random_state=2022, tree_size=3, exp_rand_tree_size=False)
rulefit.fit(X, y, feature_names=features)
preds = rulefit.predict(X)
accuracy = round(metrics.accuracy_score(y, preds), 2)
rules = rulefit.get_rules()
rules = rules[rules.coef != 0].sort_values("coef", ascending=False)

No need to provide the data — this is caused by a bug in the process of checking for duplicate rules (https://github.com/csinva/imodels/blob/master/imodels/util/extract.py#L97-L107). We will have it fixed shortly!
