LESA: Learnable Stage-Aware Predictors for Diffusion Model Acceleration
TL;DR
Diffusion models, used for generating images, often require significant computational resources, leading to slow performance. LESA, or Learnable Stage-Aware Predictors, was developed to accelerate these models by predicting the necessary computation stages.
✦ Why It Matters
Engineers can use LESA to significantly speed up image generation processes in diffusion models without sacrificing quality.
Key Takeaways
- Explore the LESA framework for improved diffusion model performance.
- Utilize multi-expert architectures for better noise-level handling.
- Leverage KAN for accurate temporal feature mapping.
- Achieve significant speedups with minimal quality loss.
How It Works
LESA employs a two-stage training process that utilizes a Kolmogorov-Arnold Network (KAN) to learn the complex temporal dynamics of the diffusion process. By integrating a multi-stage, multi-expert architecture, it assigns specialized predictors to different noise levels, allowing for more precise feature forecasting and improved consistency with standard denoising methods.
