Batch Size Impact on RoBERTa's Zero-Shot Cross-Lingual Transfer Performance in XTREME-R Tasks

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 batch size during intermediate-task training affect the zero-shot cross-lingual transfer performance of RoBERTa on XTREME-R tasks when evaluated using BLEU score differences across language pairs?
