摘要:

自2021年以来,基于深度学习的图像生成经历了范式转变,其标志是基础架构突破和计算创新。本文通过梳理架构创新和实证结果,分析了从传统生成方法到先进架构的过渡,重点关注计算高效的扩散模型和视觉Transformer架构。我们研究了Stable Diffusion、DALL-E和一致性模型(consistency models)的最新进展如何重新定义了图像合成的能力和性能边界,同时应对效率和质量方面的长期挑战。我们的分析聚焦于潜在空间表示、交叉注意力机制和参数高效训练方法的演进,这些技术使得在资源受限条件下能够加速推理。在更高效的训练方法实现更快推理的同时,ControlNet和区域注意力系统等先进控制机制也同步提升了生成精度和内容定制化能力。我们探讨了增强的多模态理解和零样本生成能力正在如何重塑各行业的实际应用。我们的分析表明,尽管生成质量和计算效率已取得显著进步,但在开发适用于工业应用的资源节约型架构和可解释生成系统方面仍存在关键挑战。本文最后规划了有前景的研究方向,包括神经架构优化和可解释生成框架。

英文摘要:

Deep learning-based image generation has undergone a paradigm shift since 2021, marked by fundamental architectural breakthroughs and computational innovations. Through reviewing architectural innovations and empirical results, this paper analyzes the transition from traditional generative methods to advanced architectures, with focus on compute-efficient diffusion models and vision transformer architectures. We examine how recent developments in Stable Diffusion, DALL-E, and consistency models have redefined the capabilities and performance boundaries of image synthesis, while addressing persistent challenges in efficiency and quality. Our analysis focuses on the evolution of latent space representations, cross-attention mechanisms, and parameter-efficient training methodologies that enable accelerated inference under resource constraints. While more efficient training methods enable faster inference, advanced control mechanisms like ControlNet and regional attention systems have simultaneously improved generation precision and content customization. We investigate how enhanced multi-modal understanding and zero-shot generation capabilities are reshaping practical applications across industries. Our analysis demonstrates that despite remarkable advances in generation quality and computational efficiency, critical challenges remain in developing resource-conscious architectures and interpretable generation systems for industrial applications. The paper concludes by mapping promising research directions, including neural architecture optimization and explainable generation frameworks.
