Researchers have developed Attribution-Guided Masking (AGM), a novel training technique designed to improve the generalization capabilities of pre-trained Transformer models in sentiment classification tasks. AGM addresses the performance degradation observed when models transfer to out-of-domain data by identifying and penalizing domain-specific spurious tokens during fine-tuning. This method, which does not require target-domain labels, demonstrated competitive performance in zero-shot transfer settings and offers interpretability by highlighting features that drive generalization gaps.
