Can Language Models Learn Embeddings of Propositional Logic Assertions? (2024.lrec-main)
Copied to clipboard
| Challenge: | Existing methods for automating reasoning can no longer be used for natural language tasks. |
| Approach: | They propose to use transformer-based language models to reason about knowledge expressed in natural language rather than using LMs to perform reasoning directly. |
| Outcome: | The proposed approach is feasible to some extent, but lacks robustness. |
There’s No Such Thing as Simple Reasoning for LLMs (2025.findings-acl)
Copied to clipboard
| Challenge: | Existing work has focused on relatively complex “many-hop” reasoning problems. |
| Approach: | They analyse the performance of fine-tuned LLMs on simple reasoning problems . they find the models remain highly brittle, being susceptible to seemingly innocent perturbations . |
| Outcome: | The proposed models fail on simple reasoning problems, but are highly brittle . they are susceptible to seemingly innocent perturbations, such as adding duplicates to the set of premises and shuffling the order in which the premises are presented. |
