Anchoring Adversarial Trajectories to Data Manifolds: A Bilevel Transfer Optimization Framework

Manifold Anchored Bilevel Transfer (MABT), a unified framework that anchors adversarial trajectories to the shared semantic subspace, is proposed, and a Hessian-free solver with linear-time complexity is developed to handle the resulting hierarchy.

Learning with Bilevel-Minimax Optimization for Efficient and Reliable Transfer Attacks

This work proposes BMAT (Bilevel-Minimax Adversarial Transfer), an integrated bottom-up solver that combines a Soft Weight Modulator and an Implicit Gradient Approximator to enable ternary coupling among initialization, surrogate adaptation, and perturbation optimization.
