Performance Comparison of Domain-Specific vs. General Intermediate-Task Training for Zero-Shot Cross-Lingual Transfer in XTREME-R

Transfer learning from large language models (LLMs) has emerged as a powerful technique to enable knowledge-based fine-tuning for a number of tasks, adaptation of models for different domains and even languages. However, it remains an open question, if and when transfer learning will work, i.e. leading to positive or negative transfer. In this paper, we analyze the knowledge transfer across three natural language processing (NLP) tasks - text classification, sentimental analysis, and sentence similarity, using three LLMs - BERT, RoBERTa, and XLNet - and analyzing their performance, by fine-tun

Research goal: How does the performance of domain-specific intermediate-task training (e.g., legal or biomedical) compare to general-language intermediate-task training for zero-shot cross-lingual transfer in XTREME-R, as measured by accuracy differences on low-resource languages?
