Indian Languages in Focus: New Benchmark IndicMMLU-Pro Tests Language Models

The Indian languages, spoken by over 1.5 billion people on the Indian subcontinent, present a particular challenge for natural language processing (NLP) research due to their rich cultural diversity, linguistic differences, and complex structures. A new benchmark called IndicMMLU-Pro aims to comprehensively evaluate the performance of large language models (LLMs) in these languages.

IndicMMLU-Pro is based on the established MMLU Pro (Massive Multitask Language Understanding) framework and covers nine major Indian languages: Hindi, Bengali, Gujarati, Marathi, Kannada, Punjabi, Tamil, Telugu, and Urdu. The benchmark encompasses a wide range of tasks in language understanding, logical reasoning, and text generation and was specifically designed to capture the nuances of Indian languages.

The development of powerful language models for Indian languages is of great importance. Applications such as machine translation, text summarization, chatbots, and voice assistants can simplify the daily lives of millions of people and improve access to information and education.

The creators of IndicMMLU-Pro place particular emphasis on high-quality data and evaluation. IndicTrans2, an advanced translation system, was used to create the dataset. Quality assurance was carried out through back-translation and the application of various validation metrics such as chrF++, BLEU, METEOR, TER, and SacreBLEU. These metrics ensure that the translations are accurate and faithful to the original text.

Initial tests with established multilingual models like GPT-4o, IndicBERT, MuRIL, and XLM-RoBERTa show that there are still significant performance differences. The results of IndicMMLU-Pro provide valuable insights into the strengths and weaknesses of current models and help to identify areas where further research and development is necessary.

IndicMMLU-Pro offers researchers and developers a standardized evaluation framework to push the boundaries of AI for Indian languages and promote the development of more accurate, efficient, and culturally sensitive models. The benchmark aims to help close the gap in NLP research for Indian languages and drive the development of innovative applications for these languages.

Mindverse, a German company specializing in AI-powered content creation, image generation, and research, is following these developments with great interest. As a provider of customized AI solutions, including chatbots, voicebots, AI search engines, and knowledge systems, Mindverse recognizes the potential of benchmarks like IndicMMLU-Pro to advance the development and optimization of language models for various languages. The results of this research can help improve the performance and accuracy of AI systems and unlock new application possibilities.
