AI总结:

MATA通过多智能体框架和小语言模型工具,提升表格问答的可靠性与灵活性,实验显示其在不同LLM上均取得最佳准确率和高效推理。

摘要:

近期大语言模型(LLMs)的进步显著提升了表格理解任务如表格问答(TableQA),但确保可靠性、可扩展性和效率仍面临挑战,尤其是在资源受限或隐私敏感环境中。本文介绍了MATA,一个基于多智能体的TableQA框架,利用多个互补的推理路径和由小语言模型构建的工具集。MATA通过多样化的推理风格为给定表格和问题生成候选答案,然后借助这些工具进行优化或选择最优答案。此外,它还集成了一个算法以最小化昂贵的LLM代理调用,从而提高整体效率。MATA在小型开源模型上表现强劲,并能轻松适应各种LLM类型。在两个难度不同的基准测试中,使用十种不同LLM的大量实验表明,MATA在准确率和高效推理方面均达到最新水平,同时避免了过度的LLM推理。我们的结果表明,精心编排多个推理路径能够实现可扩展且可靠的TableQA。代码可在https://github.com/AIDASLab/MATA上获取。

英文摘要:

Recent advances in Large Language Models (LLMs) have significantly improved table understanding tasks such as Table Question Answering (TableQA), yet challenges remain in ensuring reliability, scalability, and efficiency, especially in resource-constrained or privacy-sensitive environments. In this paper, we introduce MATA, a multi-agent TableQA framework that leverages multiple complementary reasoning paths and a set of tools built with small language models. MATA generates candidate answers through diverse reasoning styles for a given table and question, then refines or selects the optimal answer with the help of these tools. Furthermore, it incorporates an algorithm designed to minimize expensive LLM agent calls, enhancing overall efficiency. MATA maintains strong performance with small, open-source models and adapts easily across various LLM types. Extensive experiments on two benchmarks of varying difficulty with ten different LLMs demonstrate that MATA achieves state-of-the-art accuracy and highly efficient reasoning while avoiding excessive LLM inference. Our results highlight that careful orchestration of multiple reasoning pathways yields scalable and reliable TableQA. The code is available at https://github.com/AIDASLab/MATA.
