SDM: A Powerful Tool for Evaluating Model Robustness
The paper introduces Sequential Difference Maximization (SDM), a new gradient-based attack method for evaluating model robustness. It addresses the limitations of previous methods by reconstructing the objective for adversarial example generation. Experimental results show that SDM outperforms state-of-the-art techniques in both attack performance and cost-effectiveness.
- ▪SDM is designed to maximize the difference between non-ground-truth label probability upper bound and ground-truth label probability.
- ▪The method employs a three-layer optimization framework consisting of cycle, stage, and step.
- ▪SDM utilizes a negative probability loss function and a Directional Probability Difference Ratio loss function during its optimization stages.
