Abstract

There has recently been a surge of work in explanatory artificial\nintelligence (XAI). This research area tackles the important problem that\ncomplex machines and algorithms often cannot provide insights into their\nbehavior and thought processes. XAI allows users and parts of the internal\nsystem to be more transparent, providing explanations of their decisions in\nsome level of detail. These explanations are important to ensure algorithmic\nfairness, identify potential bias/problems in the training data, and to ensure\nthat the algorithms perform as expected. However, explanations produced by\nthese systems is neither standardized nor systematically assessed. In an effort\nto create best practices and identify open challenges, we provide our\ndefinition of explainability and show how it can be used to classify existing\nliterature. We discuss why current approaches to explanatory methods especially\nfor deep neural networks are insufficient. Finally, based on our survey, we\nconclude with suggested future research directions for explanatory artificial\nintelligence.\n
