摘要:

Dempster-Shafer 证据理论已被广泛应用于不确定性下的信息融合领域。现有研究大多集中在同一识别框架内组合证据。然而,在现实场景中,训练好的算法或数据往往来自不同地区或组织,数据孤岛现象普遍存在。因此,使用不同数据源或模型生成基本概率分配可能会导致异构框架,传统融合方法对此往往产生不理想的结果。为应对这一挑战,本研究提出了一种开放世界信息融合方法,称为 Full Negation Belief Transformation (FNBT),基于 Dempster-Shafer 理论。更具体地说,引入了一个准则来判断给定的融合任务是否属于开放世界设定。然后,通过扩展框架,该方法能够容纳来自异构框架的元素。最后,采用全否定机制来转换 mass 函数,使得现有的组合规则可以应用于转换后的 mass 函数以进行此类信息融合。在理论上,所提出的方法满足三个理想性质,并进行了形式化证明:mass 函数不变性、遗传性和本质冲突消除。在经验上,FNBT 在真实世界数据集的模式分类任务中展现出卓越性能,并成功解决了 Zadeh 反例,从而验证了其实际有效性。

英文摘要:

The Dempster-Shafer theory of evidence has been widely applied in the field of information fusion under uncertainty. Most existing research focuses on combining evidence within the same frame of discernment. However, in real-world scenarios, trained algorithms or data often originate from different regions or organizations, where data silos are prevalent. As a result, using different data sources or models to generate basic probability assignments may lead to heterogeneous frames, for which traditional fusion methods often yield unsatisfactory results. To address this challenge, this study proposes an open-world information fusion method, termed Full Negation Belief Transformation (FNBT), based on the Dempster-Shafer theory. More specially, a criterion is introduced to determine whether a given fusion task belongs to the open-world setting. Then, by extending the frames, the method can accommodate elements from heterogeneous frames. Finally, a full negation mechanism is employed to transform the mass functions, so that existing combination rules can be applied to the transformed mass functions for such information fusion. Theoretically, the proposed method satisfies three desirable properties, which are formally proven: mass function invariance, heritability, and essential conflict elimination. Empirically, FNBT demonstrates superior performance in pattern classification tasks on real-world datasets and successfully resolves Zadeh's counterexample, thereby validating its practical effectiveness.
