Abstract

The synthesis of high-quality images has become a cornerstone of advancements in generative modeling, with diffusion models emerging as a prominent method due to their ability to produce detailed and realistic visuals. However, achieving high fidelity often demands extensive computational resources and prolonged training durations, posing significant challenges in balancing model complexity with training efficiency. Traditional methods struggle to optimize both quality and efficiency, leaving room for innovation in design and implementation. To address this challenge, a novel diffusion-based framework is proposed that incorporates a hybrid noise scheduling mechanism and adaptive model scaling. The method uses an optimized U-Net architecture augmented with attention mechanisms to ensure high-resolution feature capture while reducing computational overhead. Furthermore, a diffusion-based training approach gradually increases model complexity, enabling faster convergence and improved efficiency. Experimental results demonstrate the efficacy of the proposed framework. On the CelebA-HQ dataset, it achieves a Fréchet Inception Distance (FID) score of 5.2, outperforming state-of-art diffusion models with a 15% reduction in training time. When tested on the CIFAR-10 dataset, the framework produces an FID score of 2.8, marking a significant improvement over existing benchmarks. These results highlight the model’s ability to maintain high image quality while substantially reducing computational costs, making it feasible for resource-constrained environments. The proposed approach bridges the gap between computational efficiency and image synthesis quality, paving the way for broader applications in industries such as gaming, design, and content generation, where high-quality visuals are critical.
