Better as Generators Than Classifiers: Leveraging LLMs and Synthetic Data for Low-Resource Multilingual Classification
This research investigates the optimal role of Large Language Models (LLMs) in low-resource multilingual classification. It finds that LLMs are more effective as generators of synthetic data for training smaller, efficient models than as direct classifiers, especially in low-resource settings. Smaller models, trained with synthetic data, frequently outperform larger generative LLMs, offering significant performance gains and computational cost reductions.
Executive Impact & Key Findings
This paper redefines the role of Large Language Models (LLMs) in multilingual classification, advocating for their use as powerful data generators rather than direct classifiers. By leveraging state-of-the-art LLMs to create synthetic datasets, we show that smaller, more computationally efficient models can be trained to match or even exceed the performance of the generative LLM, particularly in low-resource languages and less-represented tasks. This data-driven distillation approach yields significant performance gains (e.g., up to 40% in low-resource intent classification) and drastically reduces GPU hours, offering a scalable and cost-effective pathway to deploy advanced NLP solutions globally.

Model Efficiency & Distillation
The study demonstrates that LLMs can act as 'teachers,' generating synthetic data to distill their capabilities into smaller, more efficient models. This approach not only matches but often surpasses the performance of the large generator LLM, particularly in scenarios with limited human-labelled data. This is crucial for optimizing computational resources while maintaining high classification accuracy.
Low-Resource NLP
A key focus is on multilingual classification in low-resource languages (e.g., Azerbaijani, Slovenian, Welsh). The findings highlight that synthetic data generation is particularly impactful here, enabling smaller models to achieve substantial performance improvements (up to 40% in intent classification) where human-labelled data is scarce, effectively democratizing advanced NLP capabilities.
Synthetic Data Generation
The research systematically evaluates the effectiveness of LLM-generated synthetic samples for various training paradigms: fine-tuning, in-context learning, and instruction-tuning. While synthetic data proves highly beneficial, especially for less represented tasks, the study also notes its limitations compared to human data in diversity and informativeness, leading to performance plateaus with larger synthetic datasets and higher sensitivity to hyperparameters.

Case Study: English Sarcasm Detection (Niche, High-Resource Task)
For specialized tasks like sarcasm detection, synthetic samples deliver substantial benefits even in high-resource languages. Fine-tuning smaller models with synthetic data consistently outperforms the large generator LLM by 12% F1 macro score. Instruction-tuning shows even greater gains, up to 30% F1, though with higher variance. This highlights the value of synthetic data in improving performance on complicated, niche tasks, regardless of language resource level.
