Subjective Crowd Disagreements for Subjective Data: Uncovering Meaningful CrowdOpinion with Population-level Learning (2023.acl-long)
Copied to clipboard
| Challenge: | Annotator disagreements are resolved before learning takes place, but researchers question the performance of a system when annotators disagree. |
| Approach: | They propose a method that uses language features and label distributions to pool similar items into larger labels. |
| Outcome: | The proposed method is based on five publicly available datasets with varying levels of disagreements on social media and in the wild using a dataset from Facebook. |
Unlearning vs. Obfuscation: Are We Truly Removing Knowledge? (2025.emnlp-main)
Copied to clipboard
| Challenge: | Recent methods often rely on obfuscation by injecting incorrect or irrelevant information to suppress knowledge, leaving models vulnerable to probing. |
| Approach: | They propose a method that flattens the model predictive distribution over automatically generated multiple-choice questions, effectively removing knowledge about target individuals. |
| Outcome: | The proposed method achieves unlearning with over 90% refusal rate and a higher uncertainty than obfuscation on probing questions. |
VL-Calibration: Decoupled Confidence Calibration for Large Vision-Language Models Reasoning (2026.acl-long)
Copied to clipboard
| Challenge: | Existing verbalized confidence calibration methods for large vision language models optimize a single holistic confidence score using binary answer-level correctness. |
| Approach: | They propose a reinforcement learning framework that explicitly decouples confidence into visual and reasoning confidence. |
| Outcome: | Experiments show that the proposed framework decouples confidence into visual and reasoning confidence while suppressing ungrounded hallucinations while preserving valid perception. |
