Condition-Aware Neural Network for Controlled Image Generation
CVPR 2024(2024)
摘要
We present Condition-Aware Neural Network (CAN), a new method for adding
control to image generative models. In parallel to prior conditional control
methods, CAN controls the image generation process by dynamically manipulating
the weight of the neural network. This is achieved by introducing a
condition-aware weight generation module that generates conditional weight for
convolution/linear layers based on the input condition. We test CAN on
class-conditional image generation on ImageNet and text-to-image generation on
COCO. CAN consistently delivers significant improvements for diffusion
transformer models, including DiT and UViT. In particular, CAN combined with
EfficientViT (CaT) achieves 2.78 FID on ImageNet 512x512, surpassing DiT-XL/2
while requiring 52x fewer MACs per sampling step.
