About this paper
Alexey Buzovkin, Evgeny Shilov
This research from Alexey Buzovkin and Evgeny Shilov accelerates diffusion model inference by replacing the computationally intensive VAE decoder with lightweight, custom-trained alternatives. The proposed TAE-192 and EfficientViT-based decoders achieve up to 3x speedup and significantly reduce memory usage for both image and video generation, making diffusion models more accessible for resource-constrained environments.
Key insights
- Lightweight decoders based on Taming Transformers (TAE-192) and EfficientViT can significantly accelerate diffusion model inference while preserving reasonable visual quality.
- Incorporating temporal attention mechanisms into decoders is crucial for maintaining temporal coherence in video generation, preventing flickering artifacts.
- A clear trade-off exists between computational efficiency (speed, memory) and reconstruction quality (FID scores), allowing choice based on application needs.
