Numerical Understanding and Processing Skills NUPA

Number understanding and processing ability (NUPA) is a new evaluation metric proposed by Zhang Muhan's team at Peking University in December 2024. It aims to independently evaluate the performance of large language models (LLMs) in the digital field. This method focuses specifically on the ability of large models to process digital information, separating it from mathematical or common sense reasoning tasks to provide a more sophisticated and comprehensive evaluation framework.Number Cookbook: Number Understanding of Language Models and How to Improve It".

NUPA is characterized by independence, multi-dimensional assessment, and scalability.

• Independence means that NUPA evaluates digital processing capabilities separately, avoiding confusion with other tasks, making the evaluation results more accurate and able to truly reflect the performance of large models in the digital field.
• The multi-dimensional evaluation shows that NUPA not only focuses on simple numerical operations, but also covers the understanding and operation of complex data structures, such as long sequence digital operations, combination of multiple operators, and data structure analysis.
• Scalability means that NUPA is designed to be flexible and can be adjusted and optimized according to different application scenarios and requirements, making it suitable not only for academic research but also for practical applications.

The introduction of NUPA provides researchers with a clearer perspective to understand the capabilities and limitations of large models in processing digital information, and also provides a clear direction for the optimization and improvement of models. The introduction of this evaluation method will help promote research progress in related fields and promote the widespread use of large models in practical applications. The research of Zhang Muhan's team has brought new perspectives and tools to the development and application of large model technology by independently evaluating the digital processing capabilities of large models.
