Diffusion Models without Classifier-free Guidance

2 code implementations17 Feb 2025 Zhicong Tang, Jianmin Bao, Dong Chen, Baining Guo

This paper presents Model-guidance (MG), a novel objective for training diffusion model that addresses and removes of the commonly used Classifier-free guidance (CFG).

Conditional Image Generation

Simplified Diffusion Schrödinger Bridge

no code implementations21 Mar 2024 Zhicong Tang, Tiankai Hang, Shuyang Gu, Dong Chen, Baining Guo

This paper introduces a novel theoretical simplification of the Diffusion Schr\"odinger Bridge (DSB) that facilitates its unification with Score-based Generative Models (SGMs), addressing the limitations of DSB in complex data generation and enabling faster convergence and enhanced performance.

Improved Vector Quantized Diffusion Models

1 code implementation31 May 2022 Zhicong Tang, Shuyang Gu, Jianmin Bao, Dong Chen, Fang Wen

When trained on ImageNet, we dramatically improve the FID score from 11. 89 to 4. 83, demonstrating the superiority of our proposed techniques.
