Optimizing Visual Generative Models via Distribution-wise Rewards

ICML 2026poster

Conventional reinforcement learning strategies for visual generation typically employ sample-wise reward functions, yet this practice frequently results in reward hacking that degrades image diversity and introduces visual anomalies. To address these limitations, we present a novel framework that fi…

PromptEnhancer: Taming Your Rewriter for Text-to-Image Generation via Fine-Grained Reward

CVPR 2026

Recent text-to-image (T2I) diffusion models have achieved impressive progress in generating high-fidelity images, yet they often fail to faithfully follow complex user prompts, especially in attribute binding, negation, and compositional reasoning. To address this limitation, we propose PromptEnhanc

Understanding vs. Generation: Navigating Optimization Dilemma in Multimodal Models

ICLR 2026poster

Current research in multimodal models faces a key challenge where enhancing generative capabilities often comes at the expense of understanding, and vice versa. We analyzed this trade-off and identify the primary cause might be the potential conflict between generation and understanding, which creat…

Aesthetic Post-Training Diffusion Models from Generic Preferences with Step-by-step Preference Optimization

CVPR 2025poster

Generating visually appealing images is fundamental to modern text-to-image generation models. A potential solution to better aesthetics is direct preference optimization (DPO), which has been applied to diffusion models to improve general image quality including prompt alignment and aesthetics. Pop…

InstructDiffusion: A Generalist Modeling Interface for Vision Tasks

CVPR 2024poster

We present InstructDiffusion a unified and generic framework for aligning computer vision tasks with human instructions. Unlike existing approaches that integrate prior knowledge and pre-define the output space (e.g. categories and coordinates) for each vision task we cast diverse vision tasks into…

Efficient Diffusion Training via Min-SNR Weighting Strategy

ICCV 2023poster

Denoising diffusion models have been a mainstream approach for image generation, however, training these models often suffers from slow convergence. In this paper, we discovered that the slow convergence is partly due to conflicting optimization directions between timesteps. To address this issue, w…

Paint by Example: Exemplar-Based Image Editing With Diffusion Models

CVPR 2023poster

Language-guided image editing has achieved great success recently. In this paper, we investigate exemplar-guided image editing for more precise control. We achieve this goal by leveraging self-supervised training to disentangle and re-organize the source image and the exemplar. However, the naive ap…

RODIN: A Generative Model for Sculpting 3D Digital Avatars Using Diffusion

CVPR 2023highlight

This paper presents a 3D diffusion model that automatically generates 3D digital avatars represented as neural radiance fields (NeRFs). A significant challenge for 3D diffusion is that the memory and processing costs are prohibitive for producing high-quality results with rich details. To tackle thi…

StyleSwin: Transformer-Based GAN for High-Resolution Image Generation

CVPR 2022poster

Despite the tantalizing success in a broad of vision tasks, transformers have not yet demonstrated on-par ability as ConvNets in high-resolution image generative modeling. In this paper, we seek to explore using pure transformers to build a generative adversarial network for high-resolution image sy…

Vector Quantized Diffusion Model for Text-to-Image Synthesis

CVPR 2022oral

We present the vector quantized diffusion (VQ-Diffusion) model for text-to-image generation. This method is based on a vector quantized variational autoencoder (VQ-VAE) whose latent space is modeled by a conditional variant of the recently developed Denoising Diffusion Probabilistic Model (DDPM). We…
