DICE: Distilling Classifier-Free Guidance into Text Embeddings

AAAI 2026technical

Text-to-image diffusion models are capable of generating high-quality images, but suboptimal pre-trained text representations often result in these images failing to align closely with the given text prompts. Classifier-free guidance (CFG) is a popular and effective technique for improving text-imag

Coming Out of the Dark: Human Pose Estimation in Low-light Conditions

IJCAI 2025

Human pose estimation in low-light conditions is vital for applications such as surveillance and autonomous systems, yet the severe visual distortions hinder both manual annotation and estimation precision. Existing approaches typically rely on additional reference information to mitigate these issu

Fast ODE-based Sampling for Diffusion Models in Around 5 Steps

CVPR 2024highlight

Sampling from diffusion models can be treated as solving the corresponding ordinary differential equations (ODEs) with the aim of obtaining an accurate solution with as few number of function evaluations (NFE) as possible. Recently various fast samplers utilizing higher-order ODE solvers have emerge…

On the Trajectory Regularity of ODE-based Diffusion Sampling

ICML 2024poster

Diffusion-based generative models use stochastic differential equations (SDEs) and their equivalent ordinary differential equations (ODEs) to establish a smooth connection between a complex data distribution and a tractable prior distribution. In this paper, we identify several intriguing trajectory…

Simple and Fast Distillation of Diffusion Models

NeurIPS 2024poster

Diffusion-based generative models have demonstrated their powerful performance across various tasks, but this comes at a cost of the slow sampling speed. To achieve both efficient and high-quality synthesis, various distillation-based accelerated sampling methods have been developed recently. Howeve…

Cross-Layer Distillation with Semantic Calibration

AAAI 2021technical

Recently proposed knowledge distillation approaches based on feature-map transfer validate that intermediate layers of a teacher model can serve as effective targets for training a student model to obtain better generalization ability. Existing studies mainly focus on particular representation forms…

Distilling Holistic Knowledge With Graph Neural Networks

ICCV 2021poster

Knowledge Distillation (KD) aims at transferring knowledge from a larger well-optimized teacher network to a smaller learnable student network. Existing KD methods have mainly considered two types of knowledge, namely the individual knowledge and the relational knowledge. However, these two types of…
