Papers with cross-lingual memorization
Shared Path: Unraveling Memorization in Multilingual LLMs through Language Similarities (2025.emnlp-main)
Copied to clipboard
| Challenge: | Using multilingual models, we find that treating languages in isolation obscures the true patterns of memorization. |
| Approach: | They propose a graph-based correlation metric that incorporates language similarity to analyze cross-lingual memorization. |
| Outcome: | The proposed model incorporates language similarity to analyze cross-lingual memorization in 95 languages. |

| Challenge: | Large language models (LLMs) are known to memorize and recall English text from their pretraining data, but the extent to which this ability generalizes to non-English languages or transfers across languages remains unclear. |
| Approach: | They propose a dataset of 31.5K aligned excerpts from 20 books in ten languages, including English originals, official translations and new translations in six low-resource languages. |
| Outcome: | The proposed model can recall English content in translations, but perturbations reduce performance, causing the model to fail. |
