Coupling Large Language Models with Logic Programming for Robust and General Reasoning from Text (2023.findings-acl)
Copied to clipboard
| Challenge: | Large language models (LLMs) are robust and general, but their reasoning ability is not at a level to compete with the best models trained for specific natural language reasoning problems. |
| Approach: | They propose to use large language models as a few-shot semantic parser to convert natural language sentences into a logical form that serves as input for answer set programs. |
| Outcome: | The proposed model can handle multiple question-answering tasks without requiring retraining for each new task. |
COSMIC: Generalized Refusal Direction Identification in LLM Activations (2025.findings-acl)
Copied to clipboard
| Challenge: | Existing methods depend on predefined refusal templates detectable in output tokens or manual review. |
| Approach: | They propose a framework that optimally identifies steering directions and target layers using cosine similarity, entirely independent of output text. |
| Outcome: | The proposed framework achieves comparable steering effectiveness without any prior knowledge or assumptions of a model’s refusal behavior such as the use of certain refusal tokens. |
