摘要:

理解机器学习模型的决策过程,能为任务、数据以及模型失效的背后原因提供宝贵洞见。本文提出一种方法,通过对输入图像进行逐实例稀疏化,实现本质上可解释的预测。为让稀疏化过程契合人类感知,我们在具有语义意义的像素区域空间而非像素层面学习掩码。此外,我们提出一种显式方法,可动态确定每个实例所需的稀疏程度。我们在半合成与自然图像数据集上的实证表明,该本质可解释分类器比现有最优基准能产生更有意义、更易被人类理解的预测。

英文摘要:

Understanding the decision-making process of machine learning models provides valuable insights into the task, the data, and the reasons behind a model's failures. In this work, we propose a method that performs inherently interpretable predictions through the instance-wise sparsification of input images. To align the sparsification with human perception, we learn the masking in the space of semantically meaningful pixel regions rather than on pixel-level. Additionally, we introduce an explicit way to dynamically determine the required level of sparsity for each instance. We show empirically on semi-synthetic and natural image datasets that our inherently interpretable classifier produces more meaningful, human-understandable predictions than state-of-the-art benchmarks.
