让自回归图像生成模型实现精细控制,且无需大量训练。
CAR: Controllable Autoregressive Modeling for Visual Generation
- 将控制信号逐步融入多尺度潜变量,每步生成时注入引导信息。
- 在多种控制条件下表现优异,图像质量超越已有方法。
- 仅需少量训练资源即可实现强泛化,适合快速部署使用。
可控生成已成为视觉生成模型的重要方向。当前视觉生成主要依赖扩散模型和自回归模型:扩散模型(如ControlNet、T2I-Adapter)具备先进控制能力,而自回归模型虽生成质量高、可扩展性强,但在可控性与灵活性方面研究不足。本文提出一种名为CAR(Controllable AutoRegressive Modeling)的新型即插即用框架,将条件控制整合进多尺度潜变量建模中,使预训练的自回归模型能高效实现可控生成。CAR通过逐步细化并捕捉控制表示,并在每一步自回归生成中注入,引导图像生成过程。实验表明,该方法在多种条件输入下均具备优秀可控性,且生成图像质量优于现有方法。此外,CAR仅需极少训练资源即可实现良好泛化性能,显著低于预训练模型所需开销。据我们所知,这是首个针对预训练自回归视觉生成模型的控制框架。
原文摘要 · Abstract (English)
Controllable generation, which enables fine-grained control over generated outputs, has emerged as a critical focus in visual generative models. Currently, there are two primary technical approaches in visual generation: diffusion models and autoregressive models. Diffusion models, as exemplified by ControlNet and T2I-Adapter, offer advanced control mechanisms, whereas autoregressive models, despite showcasing impressive generative quality and scalability, remain underexplored in terms of controllability and flexibility. In this study, we introduce Controllable AutoRegressive Modeling (CAR), a novel, plug-and-play framework that integrates conditional control into multi-scale latent variable modeling, enabling efficient control generation within a pre-trained visual autoregressive model. CAR progressively refines and captures control representations, which are injected into each autoregressive step of the pre-trained model to guide the generation process. Our approach demonstrates excellent controllability across various types of conditions and delivers higher image quality compared to previous methods. Additionally, CAR achieves robust generalization with significantly fewer training resources compared to those required for pre-training the model. To the best of our knowledge, we are the first to propose a control framework for pre-trained autoregressive visual generation models.
