FR2ViT: Finetuning-free Token Reduction for Dense Prediction Through a Refinement-Reactivation Architecture

ICASSP 2025accepted

Token reduction is an efficient method for accelerating vision transformers. Techniques like token pruning and merging progressively decrease the number of active tokens to reduce the computation cost. However, when applied to dense prediction tasks, these techniques crudely cache low-level features…

PAI-Diffusion: Constructing and Serving a Family of Open Chinese Diffusion Models for Text-to-image Synthesis on the Cloud

ACL 2024system demonstrations

Text-to-image synthesis for the Chinese language poses unique challenges due to its large vocabulary size, and intricate character relationships. While existing diffusion models have shown promise in generating images from textual descriptions, they often neglect domain-specific contexts and lack ro…

Learn-to-Decompose: Cascaded Decomposition Network for Cross-Domain Few-Shot Facial Expression Recognition

ECCV 2022poster

"Most existing compound facial expression recognition (FER) methods rely on large-scale labeled compound expression data for training. However, collecting such data is labor-intensive and time-consuming. In this paper, we address the compound FER task in the cross-domain few-shot learning (FSL) sett…

When Facial Expression Recognition Meets Few-Shot Learning: A Joint and Alternate Learning Framework

AAAI 2022technical

Human emotions involve basic and compound facial expressions. However, current research on facial expression recognition (FER) mainly focuses on basic expressions, and thus fails to address the diversity of human emotions in practical scenarios. Meanwhile, existing work on compound FER relies heavil…
