本文介绍了一种自动计算贴现率的迭代方法。作为源的合取组合的一部分，折扣减少了源对融合结果的影响。与贴现有关的关键问题是：什么来源必须贴现，贴现到什么程度。我们提出了一种方法，共同解决这两个问题，通过计算率使用异议措施。分歧的来源进行评估，通过比较他们的平均质量函数。因此，与其他来源非常不同的来源（如由离群值产生的来源）被严重低估。迭代该贴现过程，以获得贴现源的合取组合与分类质量函数之间的最小距离。该方法的效率进行了评估，通过几个模拟。
An iterative method for automatic discounting rate computation is introduced in this paper. As part of a conjunctive combination of sources, discounting reduces the impact of a source on the result of the fusion. The key problems related to discounting are: what sources must be discounted and up to what degree. We propose a method that jointly tackles these two issues by computing rates using a dissent measure. The dissension of the sources is evaluated by comparing them to the average of their mass functions. Sources very different from others (like sources resulting from outliers) are thus heavily discounted. This discounting process is iterated so as to obtain a minimum distance between the conjunctive combination of the discounted sources and a categorical mass function. The efficiency of the method is evaluated through several simulations.
