论文摘要
机器学习(ML)公平研究倾向于主要集中于通常不透明算法或模型和/或其即时输入和输出的基于数学上的干预措施。这种过度简化的数学模型抽象了ML模型的构思,开发和最终部署的基本社会环境。由于公平本身是一个具有社会构建的概念,它源自该社会背景以及模型投入和模型本身,因此缺乏对社会背景的深入理解很容易破坏对ML公平的追求。在本文中,我们概述了改善社会背景的理解,标识和表示的三个新工具。首先,我们提出了一个基于复杂的自适应系统(CAS)的模型和社会环境的定义,这将帮助研究人员和产品开发人员扩大ML公平工作的抽象边界,以包括社会背景。其次,我们引入协作因果理论形成(CCTF),是建立社会技术框架的关键能力,该框架结合了各种心理模型和相关的因果理论,以建模基于ML的产品的问题和解决方案空间。最后,我们将基于社区的系统动态(CBSD)确定为在ML产品开发过程的所有阶段实践CCTF的强大,透明和严格的方法。最后,我们讨论了这些系统如何理解社会技术系统所嵌入的社会背景的理论方法可以改善基于公平和包容的ML产品的开发。
Machine learning (ML) fairness research tends to focus primarily on mathematically-based interventions on often opaque algorithms or models and/or their immediate inputs and outputs. Such oversimplified mathematical models abstract away the underlying societal context where ML models are conceived, developed, and ultimately deployed. As fairness itself is a socially constructed concept that originates from that societal context along with the model inputs and the models themselves, a lack of an in-depth understanding of societal context can easily undermine the pursuit of ML fairness. In this paper, we outline three new tools to improve the comprehension, identification and representation of societal context. First, we propose a complex adaptive systems (CAS) based model and definition of societal context that will help researchers and product developers to expand the abstraction boundary of ML fairness work to include societal context. Second, we introduce collaborative causal theory formation (CCTF) as a key capability for establishing a sociotechnical frame that incorporates diverse mental models and associated causal theories in modeling the problem and solution space for ML-based products. Finally, we identify community based system dynamics (CBSD) as a powerful, transparent and rigorous approach for practicing CCTF during all phases of the ML product development process. We conclude with a discussion of how these systems theoretic approaches to understand the societal context within which sociotechnical systems are embedded can improve the development of fair and inclusive ML-based products.
