Transformer research probes security flaws, training dynamics, and in-context learning limits

Researchers have identified vulnerabilities in the shuffling defense mechanism used to secure Transformer models during inference, demonstrating an attack that can extract model weights by aligning permuted activations. Another study delves into the spectral dynamics of Transformer training, revealing transient compression waves and persistent spectral gradients that encode different aspects of the learning process. Additionally, investigations into in-context learning show that prior examples can interfere with a model's ability to adapt to new tasks, with training curricula significantly impacting resilience, and that generalization depends on whether pre-training tasks are drawn from a union of subspaces or a single Gaussian distribution.

    On the (In-)Security of the Shuffling Defense in the Transformer Secure Inference

    For Transformer models, cryptographically secure inference ensures that the client learns only the final output, while the server learns nothing about the client's input. However, securely computing nonlinear layers remains a major efficiency bottleneck due to the substantial com…

    When Context Sticks: Studying Interference in In-Context Learning

    arXiv:2604.23371v1 Announce Type: new Abstract: This paper investigates context stickiness in in-context learning (ICL), a phenomenon where earlier examples in a prompt interfere with a transformer's ability to adapt to later tasks. Using synthetic regression tasks over linear an…
