Researchers have developed a new post-training pruning technique called DiT-Pruning specifically for Diffusion Transformers (DiTs), which are known for their high computational demands in image generation. Traditional pruning methods are ineffective for DiTs due to their unique architecture and weight distribution. DiT-Pruning introduces customized saliency criteria that balance weight and activation contributions, along with a clustering-aware granularity to better allocate sparse weights. Experiments show this method effectively preserves image quality, even at high sparsity levels, outperforming existing techniques. AI
IMPACT This new pruning technique could significantly reduce the computational cost and resource requirements for diffusion models, making advanced image generation more accessible.
