提出无权重价值决策框架,用模糊推理降低偏见,提升公平性。
Unweighted ranking for value-based decision making with uncertainty

- 去除主观权重,用模糊域定义评分函数优化决策
- 新方法Rankzzy在大规模问题中计算成本更低,排名性能更强
- 适合需要公平、可解释决策的智能系统应用
随着智能系统在社会中承担自主决策任务,其与人类价值观的对齐成为关键挑战。本文提出模糊无权重价值决策框架(FUW-VBDM),让代理在量化与定性标准间结合,生成以人为本的决策。通过移除先验权重,并引入针对评分函数的模糊决策域,将任何价值决策问题泛化为在权重域中寻找可行解的优化过程。为此,我们提出可定制的无权重排序方法Rankzzy,融合模糊推理以量化不确定性。数学上证明了Rankzzy在任意可接受配置下的稳定性。案例研究显示,在采用毕达哥拉斯平均聚合时,该方法在大规模价值决策问题中显著降低计算开销,且排名表现优于现有方法。
原文摘要 · Abstract (English)
As intelligent systems are increasingly implemented in our society to make autonomous decisions, their commitment to human values raises serious concerns. Their alignment with human values remains a critical challenge because it can jeopardise the integrity and security of citizens. For this reason, an innovative human-centred and values-driven approach to decision making is required. In this work, we introduce the Fuzzy-Unweighted Value-Based Decision Making (FUW-VBDM) framework, where agents incorporate both quantitative and qualitative criteria to generate human-centred decisions. We also address the normative bias introduced by stakeholders with arbitrary weights by removing prior weights and introducing a fuzzy domain of decision variables defined for a score function. This concept allows us to generalise any VBDM problem as the search for feasible solutions when optimising the score in the weight domain. To provide a solution to FUW-VBDM, we present Rankzzy, a customizable unweighted ranking method that integrates fuzzy-based reasoning to quantify uncertainty. We mathematically prove the consistency of the Rankzzy for any admissible configuration selected by stakeholders. We show the applicability of our method through an illustrative case study, which we also use as a running example. The evaluation conducted indicates a reduced computational cost in large-scale value-based decision-making problems and a strong rank performance regarding existing approaches when employing the aggregation via Pythagorean means.
