New method recalibrates Diffusion Transformers for analog compute-in-memory hardware

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel method to recalibrate Diffusion Transformers (DiTs) when used with analog compute-in-memory (CIM) hardware. This approach addresses how CIM's inherent nonidealities distort the classifier-free guidance (CFG) signal, which is crucial for generating high-quality images. By adjusting only the CFG scale during sampling, the method effectively restores generation quality, significantly reducing the gap in FID scores caused by CIM noise across various models like PixArt-Sigma, PixArt-alpha, and DiT-XL/2. AI

IMPACT Improves the efficiency and quality of image generation models on emerging analog hardware, potentially lowering costs and increasing accessibility.

    When Guidance Goes Off-Scale: Recalibrating Diffusion Transformers under Analog Compute-in-Memory Nonidealities

    arXiv:2608.19644v1 Announce Type: new Abstract: Diffusion Transformers (DiTs) incur high memory traffic and energy costs because sampling repeatedly evaluates large denoisers dominated by linear operations. Analog compute-in-memory (CIM) can alleviate these costs by executing lin…
