Multilingual Pretrained Language Models (MPLMs) have shown their strong multilinguality in recent empirical cross-lingual transfer studies. In this paper, we propose the Prompts Augmented by Retrieval Crosslingually (PARC) pipeline to improve the zero-shot performance on low-resource languages (LRLs) by augmenting the context with semantically similar sentences retrieved from a high-resource language (HRL) as prompts. PARC improves the zero-shot performance on three downstream tasks (binary sentiment classification, topic categorization and natural language inference) with multilingual paralleResearch goal: How does the inclusion of low-resource African language pretraining data impact zero-shot accuracy on XTREME-R natural language inference tasks compared to high-resource language baselines?Autonomous synthesis report generated by Assignee Research.
