ModalImmune: Immunity Driven Unlearning via Self Destructive Training

arXiv:2602.16197v1 Announce Type: new Abstract: Multimodal systems are vulnerable to partial or complete loss of input channels at deployment, which undermines reliability in real-world settings. This paper presents ModalImmune, a training framework that enforces modality immunity by intentionally and controllably collapsing selected modality information during training so the model learns joint representations that are robust to destructive modality influence. The framework combines a spectrum-adaptive collapse regularizer, an information-gain guided controller for targeted interventions, curvature-aware gradient masking to stabilize destructive updates, and a certified Neumann-truncated hyper-gradient procedure for automatic meta-parameter adaptation. Empirical evaluation on standard multimodal benchmarks demonstrates that ModalImmune improves resilience to modality removal and corruption while retaining convergence stability and reconstruction capacity.

Executive Summary

This article introduces ModalImmune, a novel training framework that enhances multimodal system resilience to partial or complete loss of input channels. By intentionally collapsing selected modality information during training, ModalImmune enforces modality immunity and promotes robust joint representations. The framework incorporates multiple techniques, including a spectrum-adaptive collapse regularizer and a certified Neumann-truncated hyper-gradient procedure, to stabilize destructive updates and adapt meta-parameters. Empirical evaluation demonstrates improved resilience to modality removal and corruption, while maintaining convergence stability and reconstruction capacity. This work contributes to the development of more reliable multimodal systems, particularly in real-world settings where input channels may be compromised.
