When and Why Does Bias Mitigation Work? (2023.findings-emnlp)

| Challenge: | Neural models exploit shallow surface features to perform language understanding tasks, rather than learning the deeper language understanding and reasoning skills that practitioners desire. |
| Approach: | They propose to use model debiasing techniques to pressure models away from spurious features and to use them to learn useful representations instead. |
| Outcome: | The proposed methods increase models' reliance on hidden biases instead of learning robust features that help them solve a task. |
Identifying and Mitigating Social Bias Knowledge in Language Models (2025.findings-naacl)

| Challenge: | Existing methods for debiasing may generate incorrect or nonsensical predictions but leave aside individual commonsense facts, resulting in modified knowledge that elicits unreasonable or undesired predictions. |
| Approach: | They propose a framework that identifies encoding locations of biases within language models and then applies the Fairness-Stamp (FAST) they also propose 'BiaScope' to evaluate the retention of commonsense knowledge and generalization across paraphrased social biase. |
| Outcome: | The proposed framework surpasses state-of-the-art baselines with superior debiasing performance while not compromising the overall model capability for knowledge retention and prediction. |

| Challenge: | Debiasing methods in NLP models focus on isolating information related to a sensitive attribute (e.g., gender or race) but instead argue that a favorable debiaser should use sensitive information ‘fairly,’ with explanations, rather than blindly eliminating it. |
| Approach: | They propose that a favorable debiasing method should use sensitive information ‘fairly,’ with explanations, rather than blindly eliminating it. |
