Investigating the significance of adversarial attacks and their relation to interpretability for radar-based human activity recognition systems

作者:

Highlights:

• We analyze adversarial threats for human action recognition using radar data.

• We expose the vulnerability of radar-based models to adversarial inputs.

• We present adversarial padding attack to be used on data with a temporal dimension.

• We show the possibility of changing prediction without perturbing activity frames

• We aim at linking adversarial vulnerability and prediction interpretability.
