On the Effect of Bit-Level Parameter Perturbations in Machine Learning and Deep Learning Models

Read the original on arXiv Machine Learning →

The paper studies how small, targeted changes to model parameters affect classical machine learning models (HMM and SVM) versus deep learning models (MLP and LSTM). Using the Drebin Android malware dataset, it finds that classical models are brittle, with a few parameter changes dramatically altering behavior, and have limited steganographic capacity. In contrast, neural networks are parameter‑redundant, allowing many parameters to be altered with minimal impact, thus supporting higher steganographic capacity.

Revealing Hidden Vulnerabilities in Autoencoders through Gradient Signal Restoration

arXiv:2505. 03646v5 Announce Type: replace-cross Abstract: Adversarial robustness of deep autoencoders (AEs) has received less attention than that of discriminative models, although their compressed latent representations induce ill-conditioned mappings that can amplify small input perturbations and destabilize reconstructions.
