Evaluating Saliency Map Explanations for Convolutional Neural Networks: A User Study

Alqaraawi, Ahmed, Schuessler, Martin, Weiß, Philipp et al.

Understand

Convolutional neural networks (CNNs) offer great machine learning performance over a range of applications, but their operation is hard to interpret, even for experts.

  • Various explanation algorithms have been proposed to address this issue, yet limited research effort has been reported concerning their user evaluation.
  • In this paper, we report on an online between-group user study designed to evaluate the performance of "saliency maps" - a popular explanation algorithm for image classification applications of CNNs.
  • Our results indicate that saliency maps produced by the LRP algorithm helped participants to learn about some specific image features the system is sensitive to.
