摘要:

在本文中,我们开发了一种度量标准,旨在评估和排名BraTS 2019不确定性量化子挑战中脑肿瘤子组织分割任务的不确定性度量。该指标旨在:(1)奖励不确定性度量,其中高置信度被分配给正确的断言,而不正确的断言被分配低置信度,以及(2)惩罚具有较高百分比的不自信正确断言的度量。在这里,基于在BraTS 2019数据集上评估的许多流行的不确定性度量,探索了该度量的组成部分的工作原理。

英文摘要:

In this paper, we develop a metric designed to assess and rank uncertainty measures for the task of brain tumour sub-tissue segmentation in the BraTS 2019 sub-challenge on uncertainty quantification. The metric is designed to: (1) reward uncertainty measures where high confidence is assigned to correct assertions, and where incorrect assertions are assigned low confidence and (2) penalize measures that have higher percentages of under-confident correct assertions. Here, the workings of the components of the metric are explored based on a number of popular uncertainty measures evaluated on the BraTS 2019 dataset.
