This paper benchmarks multilingual and monolingual LLM performance across Arabic, English, and Indic languages, examining model compression effects like pruning and quantization. Multilingual models outperform language-specific counterparts, demonstrating cross-lingual transfer. Quantization maintains accuracy while promoting efficiency, but aggressive pruning compromises performance, particularly in larger models. Why it matters: The findings highlight strategies for scalable and fair multilingual NLP, addressing hallucination and generalization errors in low-resource languages.

Researchers introduce a benchmark to evaluate the factual recall and knowledge transferability of multilingual language models across 13 languages. The study reveals that language models often fail to transfer knowledge between languages, even when they possess the correct information in one language. The benchmark and evaluation framework are released to drive future research in multilingual knowledge transfer.

MBZUAI Assistant Professor Alham Fikri Aji is presenting research at EACL 2024 on efficient NLP for low-resource languages. The study uses knowledge distillation, transferring knowledge from a larger model (ChatGPT) to a smaller one using synthetic instruction data. The goal is to achieve similar performance with less computational resources, focusing on underrepresented languages. Why it matters: This work addresses the need for more accessible and inclusive NLP technologies, especially for languages lacking extensive datasets and computational resources.

This paper explores cross-lingual transfer in Arabic language models, which are typically pretrained on Modern Standard Arabic (MSA) but expected to generalize to diverse dialects. The study uses probing on 3 NLP tasks and representational similarity analysis to assess transfer effectiveness. Results show transfer is uneven across dialects, partially linked to geographic proximity, and models trained on all dialects exhibit negative interference. Why it matters: The findings highlight challenges in cross-lingual transfer for Arabic NLP and raise questions about dialect similarity for model training.

Researchers introduce Swan, a family of Arabic-centric embedding models including Swan-Small (based on ARBERTv2) and Swan-Large (based on ArMistral). They also propose ArabicMTEB, a benchmark suite for cross-lingual, multi-dialectal Arabic text embedding performance across 8 tasks and 94 datasets. Swan-Large achieves state-of-the-art results, outperforming Multilingual-E5-large in most Arabic tasks. Why it matters: The new models and benchmarks address a critical need for high-quality Arabic language models that are both dialectally and culturally aware, enabling more effective NLP applications in the region.
