The Scale Invariant Image Diffuser (S2ID) presents a novel approach to image generation that overcomes limitations of traditional diffusion architectures like UNet and DiT models, which struggle with artifacts when scaling image resolutions. S2ID leverages a unique method of treating image data as a continuous function rather than discrete pixels, allowing for the generation of clean, high-resolution images without the usual artifacts. This is achieved by using a coordinate jitter technique that generalizes the model's understanding of images, enabling it to adapt to various resolutions and aspect ratios. The model, trained on standard MNIST data, demonstrates impressive scalability and efficiency with only 6.1 million parameters, suggesting significant potential for applications in image processing and computer vision. This matters because it represents a step forward in creating more versatile and efficient image generation models that can adapt to different sizes and shapes without losing quality.

The Scale Invariant Image Diffuser (SIID) is a new diffusion model architecture designed to overcome limitations in existing models like UNet and DiT, which struggle with changes in pixel density and resolution. SIID achieves this by using a dual relative positional embedding system that allows it to maintain image composition across varying resolutions and aspect ratios, while focusing on refining rather than adding information when more pixels are introduced. Trained on 64×64 MNIST images, SIID can generate readable 1024×1024 images with minimal deformities, demonstrating its ability to scale effectively without relying on data augmentation. This matters because it introduces a more flexible and efficient approach to image generation, potentially enhancing applications in fields requiring high-resolution image synthesis.
