Core Innovation
This paper identifies Test-Time Training as a linear-complexity attention architecture structurally compatible with Softmax attention, allowing direct weight inheritance from pretrained models. It introduces key instance normalization and a locality enhancement module to align representational properties, enabling effective fine-tuning and acceleration of large vision Transformers.
Why It Matters
Transformer models face quadratic complexity bottlenecks that limit scalability and increase inference costs. This solution reduces computational overhead by linearizing attention mechanisms, enabling faster and more efficient deployment of large pretrained models like Stable Diffusion. It supports scalable, cost-effective AI workflows in industries relying on high-quality generative models.
