The AVID taxonomy is intended to serve as a common foundation for data science/AI engineering, product, and policy teams to manage potential risks at different stages of a developing an AI system. In spirit, this taxonomy is analogous to MITRE ATT&CK for cybersecurity vulnerabilities, and MITRE ATLAS for adversarial attacks on ML systems.

At a high level, the AVID taxonomy consists of two views, intended to facilitate the work of two different user personas.

  • Effect view: for the auditor persona that aims to assess risks for a ML system of components of it.
  • Lifecycle view: for the developer persona that aims to build an end-to-end ML system while being cognizant of potential risks.

Based on case-specific needs, people involved with building a ML system may need to operate as either of the above personas.

Effect (SEP) view

The domains, categories, and subcategories in this view provide a ‘risk surface’ for the AI artifact being evaluated, may it be a dataset, model, or the whole system. This view contains three top-level domains:

Each domain is divided into a number of categories and subcategories, each of which is assigned a unique identifier. Figure 1 presents a holistic view of this AVID taxonomy matrix. See the individual pages for Security, Ethics, Performance for more details.

Lifecycle view

The stages in this view represent high-level sequential steps of a typical ML workflow. Following the widely-used Cross-industry standard process for data mining (CRISP-DM) framework, we designate six stages in this view.

L01Business Understanding
L02Data Understanding
L03Data Preparation
L04Model Development

Figure 2 reconciles the two different views of the AVID taxonomy. We conceptually represent the potential space of risks in three dimensions, consisting of the risk domain—S, E, or P—a specific vuln pertains to; the (sub)category within a chosen domain; and the development lifecycle stage of a vuln. The SEP and lifecycle views are simply two different sections of this three-dimensional space.
