摘要:

AI-Powered Database(AI-DB)是一种新型的关系数据库系统,它使用自监督神经网络,数据库嵌入,来支持关系表上的语义SQL查询。在本文中,我们描述了一个数据库内可解释性基础设施的架构和实现,旨在为AI-DB支持的语义SQL查询的排名结果提供简单,透明和相关的见解。我们引入了一种新的基于同现的可解释性方法来捕获关系实体之间的关系,并描述了一种空间高效的概率草图实现来存储和处理同现计数。我们的方法提供了查询不可知(全球)和查询特定(本地)的可解释性。实验评估表明,我们的数据库中的概率方法提供了相同的可解释性质量的精确的空间效率低下的方法,同时提供可扩展和空间效率的运行时行为(高达8倍的空间节省),没有任何用户干预。

英文摘要:

AI-Powered database (AI-DB) is a novel relational database system that uses a self-supervised neural network, database embedding, to enable semantic SQL queries on relational tables. In this paper, we describe an architecture and implementation of in-database interpretability infrastructure designed to provide simple, transparent, and relatable insights into ranked results of semantic SQL queries supported by AI-DB. We introduce a new co-occurrence based interpretability approach to capture relationships between relational entities and describe a space-efficient probabilistic Sketch implementation to store and process co-occurrence counts. Our approach provides both query-agnostic (global) and query-specific (local) interpretabilities. Experimental evaluation demonstrate that our in-database probabilistic approach provides the same interpretability quality as the precise space-inefficient approach, while providing scalable and space efficient runtime behavior (up to 8X space savings), without any user intervention.
