Rashid: A Cipher-Based Framework for Exploring In-Context Language Learning
This addresses the problem of limited experimentation and assessment in ICLL research for low-resource languages, though it is incremental as it provides a simulation-based approach rather than a new learning paradigm.
The researchers tackled the challenge of studying in-context language learning (ICLL) for unseen languages by introducing Rashid, a framework that reversibly ciphers high-resource languages to create artificial unseen languages with access to existing resources, enabling comprehensive evaluation of ICLL methods and strategies across diverse tasks.
Where there is growing interest in in-context language learning (ICLL) for unseen languages with large language models, such languages usually suffer from the lack of NLP tools, data resources, and researcher expertise. This means that progress is difficult to assess, the field does not allow for cheap large-scale experimentation, and findings on ICLL are often limited to very few languages and tasks. In light of such limitations, we introduce a framework (Rashid), for studying ICLL wherein we reversibly cipher high-resource languages (HRLs) to construct truly unseen languages with access to a wide range of resources available for HRLs, unlocking previously impossible exploration of ICLL phenomena. We use our framework to assess current methods in the field with SOTA evaluation tools and manual analysis, explore the utility of potentially expensive resources in improving ICLL, and test ICLL strategies on rich downstream tasks beyond machine translation. These lines of exploration showcase the possibilities enabled by our framework, as well as providing actionable insights regarding current performance and future directions in ICLL.
