arXiv:2604.10098v2 Announce Type: replace Abstract: As the foundational architecture of modern machine learning, Transformers have driven remarkable progress across diverse AI domains. Despite their transformative impact, a persistent challenge across various Transformers is Attention Sink (AS), in which a disproportionate amount of attention is focused on a small subset of specific yet uninformative tokens. AS complicates interpretability, significantly affecting the training and inference dynamics, and exacerbates issues such as hallucinations. In recent years, substantial research has been
The proliferation of Transformer-based models across diverse AI applications necessitates deeper understanding and mitigation of their inherent limitations, like Attention Sink, as the technology matures.
Attention Sink significantly impacts the interpretability, training efficiency, inference dynamics, and reliability of large AI models, directly affecting their commercial deployment and trustworthiness.
Increased focus on understanding and mitigating Attention Sink will lead to more robust, efficient, and reliable Transformer architectures, improving the performance and reducing the failure modes of AI systems.
