Beyond Decision Boundaries: Relational Geometry Attacks on Contrastive Embedding Manifolds

arXiv:2608. 10237v1 Announce Type: new Abstract: Contrastive learning and Siamese embedding models have become the foundation of modern verification systems, where decisions are governed not by discrete classification boundaries, but by relational geometry in embedding space.

Structural Adversarial Attacks on Relational Deep Learning under Integrity Constraints

arXiv:2607. 07089v1 Announce Type: new Abstract: Relational Deep Learning (RDL) has become a standard methodology for machine learning on relational databases: the database is encoded as a heterogeneous temporal graph in which tuples become nodes and primary-key to foreign-key (PK-FK) dependencies become typed edges, over which a graph neural network is trained for downstream prediction.

Structural Adversarial Attacks on Relational Deep Learning under Integrity Constraints

Relational Deep Learning (RDL) has become a standard methodology for machine learning on relational databases: the database is encoded as a heterogeneous temporal graph in which tuples become nodes and primary-key to foreign-key (PK-FK) dependencies become typed edges, over which a graph neural network is trained for downstream prediction. We study the adversarial robustness of this pipeline.

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

The paper introduces Manifold Anchored Bilevel Transfer (MABT), a framework that aligns adversarial attack trajectories with the intrinsic data manifold to reduce surrogate-specific overfitting. MABT employs a relaxed manifold-anchoring operator as a semantic rectifier and formulates transfer attack generation as a distributional bilevel optimization problem, learning geometry-aligned initializations that minimize expected transfer risk. A Hessian-free solver with linear-time complexity is developed to efficiently solve the resulting hierarchy, and experiments show improved transferability across 10 attackers, 28 configurations, various victim models, and defense mechanisms.

FSPGD: Rethinking Black-box Attacks on Semantic Segmentation

FSPGD introduces a feature-space black-box attack for semantic segmentation that targets intermediate representations rather than just output logits. The method uses a dual loss: an external loss to disrupt cross-model feature alignment and an internal loss to reduce consistency among same-class instances. Experiments on Pascal VOC 2012 and Cityscapes show that FSPGD outperforms existing logit-level and segmentation-specific attacks across CNN and Transformer backbones, and its adversarial examples improve robustness when used for training.
