Parameter Free Attention

Parameter-free attention mechanisms aim to improve the efficiency and performance of various deep learning models without increasing the number of trainable parameters. Current research focuses on integrating these mechanisms into existing architectures like transformers and convolutional neural networks for tasks such as image super-resolution, semantic segmentation, and diffusion model enhancement, often employing novel algorithms based on weighted ranking or symmetric activation functions. This approach offers significant advantages by reducing computational costs and memory requirements, leading to faster inference speeds and making advanced models more accessible for resource-constrained applications. The resulting improvements in efficiency and performance are demonstrably impactful across diverse computer vision tasks.
