| Challenge: | Existing methods for uncertainty estimation are inadequate for safety-critical applications. |
| Approach: | They propose a method that uses the distances from neighbors and the ratio of labels in neighbors to estimate uncertainty. |
| Outcome: | The proposed method outperforms baseline and density-based methods in calibration and uncertainty metrics. |

| Challenge: | Existing methods for text classification tasks are inherently ambiguous and can cause errors. |
| Approach: | They propose a method that combines epistemic and aleatoric uncertainty to estimate toxicity detection errors. |
| Outcome: | The proposed method outperforms existing methods for toxicity detection and other ambiguous text classification tasks. |
