There are various adversarial attacks on neural networks. Many previous studies have reported that neural networks are vulnerable to those adversarial attacks. In the perspective of safety, we have to evaluate a model's robustness against those attacks. However, it is not simple to determine whether a model is robust to adversarial attacks since there exist multiple properties for a model. Mostly, we have measured robustness with accuracy against those attacks so far. In a recent study, it was shown that this measurement methodology is not sufficient to capture all the robustness properties. In this paper, we present a simple new metric that captures sparsity, a robustness property against L-infinity sparse attacks. Through several experiments we show that there is necessity to use diverse metric to evaluate a model's robustness and our new metric works well.
