Effectiveness of Domain-Specific Intermediate-Task Training in Zero-Shot Cross-Lingual Transfer

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 effectiveness of English intermediate-task training in zero-shot cross-lingual transfer vary when comparing the performance of intermediate tasks from the same domain (e.g., natural language inference) versus different domains (e.g., sentiment analysis) in XTREME-R?
