For black-box attacks, the gap between substitute model and victim is usually large, which manifests as a weak attack performance. Motivated by observation that transferability of adversarial examples can be improved attacking diverse models simultaneously, augmentation methods simulate different using transformed images are proposed. However, existing transformations for spatial domain do not ...

We propose a novel, frequency-domain approach to the analysis of gravitational-wave ringdown signal binary black holes and identification quasinormal mode frequencies remnant. Our avoids issues spectral leakage that would normally be expected (associated with abrupt start ringdown) by modeling inspiral merger parts using flexible sum sine-Gaussian wavelets truncated at onset ringdown. Performin...
