Abstract
En 中文
• We propose SyncQ-DiT, a temporal anomaly-aware PTQ framework for DiTs. • ARC synchronizes timestep-varying anomaly channels for precise low-bit scaling. • ATG clusters timesteps by anomaly distributions to reduce calibration cost. • RGQ reorders channels to minimize intra-group variance in group quantization. • SyncQ-DiT achieves state-of-the-art W4A4 PTQ performance on DiT and PixArt.
