本文介绍了embComp,这是一种用于比较两个嵌入的新方法,这些嵌入捕获了对象之间的相似性,例如Word和文档嵌入。我们调查了比较这些嵌入空间有用的场景。从这些场景中,我们派生出常见的任务,引入支持这些任务的可视化分析方法,并将它们组合到一个全面的系统中。EmbComp的核心功能之一是总览可视化,它基于度量对象周围局部结构差异的指标。通过对嵌入的这些局部指标进行总结,提供了异同的全局概述。局部视图允许比较所选对象周围的局部结构,并将此局部信息与全局视图相关联。EmbCompa集成并连接所有这些组件,支持一系列分析工作流,帮助了解嵌入空间之间的异同。我们通过在几个用例中应用我们的方法来评估我们的方法,包括通过词向量嵌入理解语料库差异,以及理解生成嵌入的算法差异。
This article introducesembComp, a novel approach for comparing two embeddings that capture the similarity between objects, such as word and document embeddings. We survey scenarios where comparing these embedding spaces is useful. From those scenarios, we derive common tasks, introduce visual analysis methods that support these tasks, and combine them into a comprehensive system. One ofembComp’s central features are overview visualizations that are based on metrics for measuring differences in the local structure around objects. Summarizing these local metrics over the embeddings provides global overviews of similarities and differences. Detail views allow comparison of the local structure around selected objects and relating this local information to the global views. Integrating and connecting all of these components,embCompsupports a range of analysis workflows that help understand similarities and differences between embedding spaces. We assess our approach by applying it in several use cases, including understanding corpora differences via word vector embeddings, and understanding algorithmic differences in generating embeddings.
