When Benchmarks Leak: Inference-Time Decontamination for LLMs (2026.acl-long)
Copied to clipboard
| Challenge: | a large number of large language models (LLMs) are being evaluated for their performance, but their reliability is threatened by test set contamination. |
| Approach: | They propose a framework that decontaminates large language models by applying small perturbations to the input embedding space. |
| Outcome: | The proposed framework achieves strong decontamination effectiveness while incurring minimal degradation in benign utility. |
