Strike (with) a Pose: Neural Networks Are Easily Fooled by Strange Poses of Familiar Objects

Alcorn, Michael A., Li, Qi, Gong, Zhitao et al.

Understand

Despite excellent performance on stationary test sets, deep neural networks (DNNs) can fail to generalize to out-of-distribution (OoD) inputs, including natural, non-adversarial ones, which are common in real-world settings.

  • In this paper, we present a framework for discovering DNN failures that harnesses 3D renderers and 3D models.
  • That is, we estimate the parameters of a 3D renderer that cause a target DNN to misbehave in response to the rendered image.
  • Using our framework and a self-assembled dataset of 3D objects, we investigate the vulnerability of DNNs to OoD poses of well-known objects in ImageNet.
