Concept-Based Explanations to Test for False Causal Relationships Learned by Abusive Language Classifiers

Isar Nejadgholi, Svetlana Kiritchenko, Kathleen C. Fraser +1

Classifiers tend to learn a false causal relationship between an over-represented concept and a label, which can result in over-reliance on the concept and compromised classificati…
