Researchers have developed a novel method called SVDtrunc for compressing Diffusion Transformers (DiTs), a popular architecture for text-to-image generation. Unlike previous approaches that could lead to performance degradation, SVDtrunc uses a two-step process involving block-level rank allocation and truncated singular value decomposition. This method allows for significant parameter reduction, retaining near-full performance even at 68% compression and remaining competitive at 57%. The technique has demonstrated superior results across multiple benchmarks, outperforming existing methods and complementing other efficiency improvements like diffusion step reduction. AI
