Text-to-image synthesis for the Chinese language poses unique challenges due
to its large vocabulary size, and intricate character relationships. While
existing diffusion models have shown promise in generating images from textual
descriptions, they often neglect domain-specific contexts and lack robustness
in handling the Chinese language. This paper introduces PAI-Diffusion, a
comprehensive framework that addresses these limitations. PAI-Diffusion
incorporates both general and domain-specific Chinese diffusion models,
enabling the generation of contextually relevant images. It explores the
potential of using LoRA and ControlNet for fine-grained image style transfer
and image editing, empowering users with enhanced control over image
generation. Moreover, PAI-Diffusion seamlessly integrates with Alibaba Cloud's
Machine Learning Platform for AI, providing accessible and scalable solutions.
All the Chinese diffusion model checkpoints, LoRAs, and ControlNets, including
domain-specific ones, are publicly available. A user-friendly Chinese WebUI and
the diffusers-api elastic inference toolkit, also open-sourced, further
facilitate the easy deployment of PAI-Diffusion models in various environments,
making it a valuable resource for Chinese text-to-image synthesis.

We present LR-GAN: an adversarial image generation model which takes scene
structure and context into account. Unlike previous generative adversarial
networks (GANs), the proposed GAN learns to generate image background and
foregrounds separately and recursively, and stitch the foregrounds on the
background in a contextually relevant manner to produce a complete natural
image. For each foreground, the model learns to generate its appearance, shape
and pose. The whole model is unsupervised, and is trained in an end-to-end
manner with gradient descent methods. The experiments demonstrate that LR-GAN
can generate more natural images with objects that are more human recognizable
than DCGAN.

我们提出了 LR-GAN，这是一种考虑场景结构和上下文的对抗性图像生成模型，使用前景和背景分别和递归地生成，并以相关上下文方式将前景缝合在背景上，以产生完整自然图像。
