ZaliQL:一个基于SQL的大数据因果推理框架

ZaliQL: A SQL-Based Framework for Drawing Causal Inference from Big Data

University of Washington(华盛顿大学)

Babak Salimi, Dan Suciu

摘要:

从观测数据中进行因果推断是统计学和计算机科学中积极研究和发展的课题。为此开发了许多工具包,这些工具包依赖于统计软件。然而,这些工具包不能扩展到大型数据集。在本文中,我们描述了一套技术表示因果推理任务的观察数据在SQL中。该套件支持最先进的因果推理方法,并在数据库引擎中大规模运行。此外,我们介绍了几种优化技术,显着加快因果推理,无论是在在线和离线设置。我们通过真实数据集的实验来评估我们的技术的质量和性能。

英文摘要:

Causal inference from observational data is a subject of active research and development in statistics and computer science. Many toolkits have been developed for this purpose that depends on statistical software. However, these toolkits do not scale to large datasets. In this paper we describe a suite of techniques for expressing causal inference tasks from observational data in SQL. This suite supports the state-of-the-art methods for causal inference and run at scale within a database engine. In addition, we introduce several optimization techniques that significantly speedup causal inference, both in the online and offline setting. We evaluate the quality and performance of our techniques by experiments of real datasets.
