Prompts Slash Low-Resource Lang Contamination
๐ก80%โ5% contamination fix for rare langsโno fine-tuning needed on top LLMs.
โก 30-Second TL;DR
What Changed
Vocab contamination drops 80%โ5% for Tulu via prompts
Why It Matters
Enables zero-shot handling of ultra-low-resource languages, expanding LLM utility without data/fine-tuning.
What To Do Next
Adapt the 5-layer prompt from arxiv.org/abs/2602.15378v1 for your low-resource language tasks.
Key Points
- โขVocab contamination drops 80%โ5% for Tulu via prompts
- โข5 layers: phonology, morphology, negative Kannada constraints
- โขNo fine-tuning; works on frozen GPT-4o, Llama 3.1 70B

๐ Enhanced Key Takeaways
- โขTranslation-induced stealth contamination boosts English test accuracy by up to 11.3 percentage points without triggering standard monolingual detectors, highlighting cross-lingual leakage risks relevant to low-resource languages like Tulu[1].
- โขInference-time decontamination methods like ITD and DeconIEP reduce accuracy by 19โ23 percentage points on contaminated splits by perturbing test instances, offering an alternative to prompting for contamination mitigation[1].
- โขCoDeC detects contamination by measuring logit decreases when augmenting prompts with in-context examples from the same dataset, providing a model-agnostic score for memorized data[2].
