Performance Comparison of XLM-R and mBERT on XTREME-R with Sequential vs. Simultaneous Fine-Tuning for Morphologically Complex

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 performance of XLM-R and mBERT on the XTREME-R benchmark compare when using sequential versus simultaneous fine-tuning on typologically distant language pairs, specifically for morphologically complex languages like Turkish and Yoruba?
