摘要:

人脸表情识别是心理学和机器学习领域的重要研究课题,具有广泛的应用前景。尽管对人类FER进行了大量的研究,并且通过深度神经网络(DNN)使计算FER取得了相当大的进展,但在比较DNN与人类表现相当的程度方面所做的工作相对较少。在这项工作中,我们比较了识别性能和注意力模式的人类和机器在一个两个选择强迫选择FER任务。在这里,人类的注意力是通过点击数据收集的,这些数据逐渐揭示了一张脸,而模型的注意力是使用三种不同的流行技术从可解释的人工智能中获得的:CAM,GradCAM和极值扰动。在这两种情况下,性能都以正确率为单位收集。在这项任务中,我们发现人类的表现明显优于机器。在注意力模式方面,我们发现极端扰动在任务期间与人类注意力地图的整体拟合最好。

英文摘要:

Facial expression recognition (FER) is a topic attracting significant research in both psychology and machine learning with a wide range of applications. Despite a wealth of research on human FER and considerable progress in computational FER made possible by deep neural networks (DNNs), comparatively less work has been done on comparing the degree to which DNNs may be comparable to human performance. In this work, we compared the recognition performance and attention patterns of humans and machines during a two-alternative forced-choice FER task. Human attention was here gathered through click data that progressively uncovered a face, whereas model attention was obtained using three different popular techniques from explainable AI: CAM, GradCAM and Extremal Perturbation. In both cases, performance was gathered as percent correct. For this task, we found that humans outperformed machines quite significantly. In terms of attention patterns, we found that Extremal Perturbation had the best overall fit with the human attention map during the task.
