arXiv:2606.27784v1 Announce Type: cross Abstract: The existence of adversarial attacks is often attributed to the presence of non-robust features in neural networks. While prior defenses reduce their impact via pruning, masking, or feature recalibration, we instead propose to jointly learn to amplify and attenuate these signals through a simple activation scaling mechanism. To this end, we introduce Activation Amplification and Attenuation (A3), a lightweight plug-in module that enhances adversarial robustness with minimal modifications of the activations. A3 dynamically rescales the activatio
This research addresses a fundamental vulnerability in neural networks (adversarial attacks) which is critical for the reliable deployment of AI systems, especially as AI applications grow in sensitivity and autonomy.
Improved adversarial robustness is crucial for trust and security in AI, as it directly impacts the reliability of AI systems in real-world, potentially hostile environments, and can prevent system failures or malicious manipulation.
This development proposes a new, lightweight method to enhance AI model security against adversarial attacks, moving beyond traditional pruning or masking techniques by directly manipulating activation signals.
