Blackbox Attacks via Surrogate Ensemble Search
TLDR: Optimizing a weighted loss function over surrogate ensemble provides highly successful and query efficient blackbox (targeted and untargeted) attacks.GAMA: Generative Adversarial Multi-Object Scene Attacks
TLDR: A joint vision/language model (such as CLIP) provides image and text embeddings. The generative model learns to generate perturbed images that are close to image embedding and far from the text embedding of the clean images.
