| Challenge: | valence and arousal are functionally equivalent across social media platforms . americans display higher emotional intensity than Chinese users . |

Robust Bias Detection in MLMs and its Application to Human Trait Ratings (2025.findings-naacl)
Copied to clipboard
| Challenge: | Existing methods to assess demographic bias in MLMs ignore random variability of templates and target concepts, and neglect bias quantification. |
| Approach: | They propose a systematic statistical approach to assess bias in MLMs using mixed models to account for random effects, pseudo-perplexity weights for sentences derived from templates and quantify bias using statistical effect sizes. |
| Outcome: | The proposed method matches on bias scores in magnitude and direction with small to medium effect sizes. |
