People Make Better Edits: Measuring the Efficacy of LLM-Generated Counterfactually Augmented Data for Harmful Language Detection

1 code implementation2 Nov 2023 Indira Sen, Dennis Assenmacher, Mattia Samory, Isabelle Augenstein, Wil van der Aalst, Claudia Wagner

CADs introduce minimal changes to existing training data points and flip their labels; training on them may reduce model dependency on spurious features.
