2021 The Journal of Artificial Intelligence Research  
We explore the feasibility of learning implicitly from visually unrealistic, task-relevant stimuli, which are synthesized by exciting the neurons of a trained deep neural network.  ...  This work investigates a simple yet unconventional approach for anonymized data synthesis to enable third parties to benefit from such anonymized data.  ...  We want to thank the anonymous reviewers for their valuable feedback that helped us to substantially improve this manuscript.  ...
