arXiv:2604.12277v2 Announce Type: replace Abstract: Pretrained text encoders are prone to shortcut learning, relying on token-label correlations that fail once the distribution shifts in deployment. Existing shortcut mitigation methods mainly operate at training time and assume access to training data, training dynamics, or shortcut annotations, which are hardly available during deployment, where only the converged model remains. We show that this model alone suffices to mitigate shortcuts during deployment: a biased model internalizes a signal of its learned shortcuts that can be captured via
As AI models become more pervasive, addressing their inherent biases and 'shortcut' learning without retraining is critical for reliable deployment across diverse real-world scenarios.
This research provides a method to enhance the robustness and trustworthiness of deployed AI models, directly impacting their real-world efficacy and safety, especially in critical applications.
AI models can now potentially mitigate problematic 'shortcuts' post-training and during deployment, removing a significant barrier to their widespread and safe adoption in dynamic environments.

Reduced incidence of AI failures due to unintended correlations in deployed models.
Increased trust and faster adoption of AI in sensitive applications where reliability is paramount.
Potentially democratizes advanced AI deployment by making models more adaptable with less specialized post-deployment intervention.
