Domain-Specific Intermediate Task Training for Cross-Lingual Transfer in Low-Resource Languages

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: What is the impact of domain-specific intermediate task training (e.g., biomedical or legal tasks) on cross-lingual transfer performance for low-resource languages in XTREME?
