Are LLMs classical or nonmonotonic reasoners? Lessons from generics (2024.acl-short)
Copied to clipboard
| Challenge: | Recent research on nonmonotonic reasoning has provided evidence of impressive performance and flexible adaptation to machine generated or human critique. |
| Approach: | They propose to use generics to explain why birds fly and exceptions such as penguins don't fly to maintain stable beliefs on truth conditions of generics. |
| Outcome: | The proposed task features generics, such as ‘Birds fly’, and exceptions, ‘Penguins don’t fly’. |

| Challenge: | Existing methods to distinguish causally related words from spurious correlations are limited by the number of causally correlated words in a sentence. |
| Approach: | They propose to use probabilistic probability of necessity and probability of sufficiency to identify causal relationships rather than spurious correlations between words and class labels. |
| Outcome: | The proposed method is based on a contrastive learning approach name CPNS and is validated on public datasets. |
