新的机器学习方法处理具有区间目标的专家分歧

研究人员开发了一种新颖的机器学习方法,用于处理表现出分歧或模糊性的专家标签,特别是当专家提供区间目标而不是精确值时。该方法保留了个体专家的区间,并使用具有 Cramér 距离目标的 Beta 分布混合模型来对其进行建模。它还将预测不确定性分解为组件内不确定性、组件间不确定性和模型不确定性,并通过称为分解匹配的过程将这些组件与它们各自的标签端来源对齐。在海冰浓度数据测试中,与硬标签相比,该模型实现了 31% 的平均绝对误差降低,并超越了现有的聚合、区间分布和区间回归基线。 AI

影响 这项研究为在专家数据本质上不确定或多样的情况下训练模型提供了一种更稳健的方法,有可能提高在具有主观或不精确专家标签的领域的性能。
