Computational Efficiency of Sequential vs. Simultaneous Fine-Tuning for Cross-Lingual Euphemism Detection on XTREME-R

Euphemisms are culturally variable and often ambiguous, posing challenges for language models, especially in low-resource settings. This paper investigates how cross-lingual transfer via sequential fine-tuning affects euphemism detection across five languages: English, Spanish, Chinese, Turkish, and Yoruba. We compare sequential fine-tuning with monolingual and simultaneous fine-tuning using XLM-R and mBERT, analyzing how performance is shaped by language pairings, typological features, and pretraining coverage. Results show that sequential fine-tuning with a high-resource L1 improves L2 perfo Research goal: How does the computational efficiency (inference time and memory usage) of sequential fine-tuning compare to simultaneous fine-tuning for cross-lingual euphemism detection on XTREME-R when scaling to larger language sets?
