RAISE: Requirement-Adaptive Evolutionary Refinement for Training-Free Text-to-Image Alignment

CVPR 2026

Recent text-to-image (T2I) diffusion models achieve remarkable realism, yet faithful prompt-image alignment remains challenging, particularly for complex prompts with multiple objects, relations, and fine-grained attributes. Existing training-free inference-time scaling methods rely on fixed iterati

Qua2SeDiMo: Quantifiable Quantization Sensitivity of Diffusion Models

AAAI 2025technical

Diffusion Models (DM) have democratized AI image generation through an iterative denoising process. Quantization is a major technique to alleviate the inference cost and reduce the size of DM denoiser networks. However, as denoisers evolve from variants of convolutional U-Nets toward newer Transform…

Re-ttention: Ultra Sparse Visual Generation via Attention Statistical Reshape

NeurIPS 2025poster

Diffusion Transformers (DiT) have become the de-facto model for generating high-quality visual content like videos and images. A huge bottleneck is the attention mechanism where complexity scales quadratically with resolution and video length. One logical way to lessen this burden is sparse attentio…
