I am currently a researcher at Huawei Noah's Ark Lab (Hong Kong). I obtained my Ph.D. degree from
CSE Department,
HKUST,
advised by Prof. Shueng-Han Gary Chan. I interned at Snap Research working on efficient text-to-image models, with
Jian Ren and
Anil Kag. I also interned at
MSRA,
working with Fangyun Wei on multimodal large language models (MLLM).
I received my B.Eng. in Electrical Engineering from Edison Experimental Class,
Zhejiang University.
My research topics include Efficient Foundation Models and Multi-modal Modeling.

CVPR, 2025 project /
pdf
We propose SnapGen, the first text-to-image model (379M) that can synthesize high-resolution images (1024x1024) on mobile devices in 1.4s, and achieve 0.66 on GenEval metric.
AsCAN: Asymmetric Convolution-Attention Networks for Efficient Recognition and Generation
Anil Kag, Huseyin Coskun, Jierun Chen, Junli Cao, Willi Menapace, Aliaksandr Siarohin, Sergey Tulyakov, Jian Ren
NeurIPs, 2024 project /
pdf
We introduce AsCAN, a hybrid neural network with asymmetric convolutional and transformer blocks, offering superior performance and efficiency across image recognition and generation tasks.
Revisiting Referring Expression Comprehension Evaluation in the Era of Large Multimodal Models Jierun Chen*, Fangyun Wei*, Jinjing Zhao, Sizhe Song, Bohuai Wu, Zhuoxuan Peng, S.-H. Gary Chan, Hongyang Zhang
Preprint, 2024 pdf /

dataset
We clean the widely-adopted RefCOCO,+,g benchmarks and introduce Ref-L4, a New REC benchmark in the LMM Era.
StableKD: Breaking Inter-block Optimization Entanglement for Stable Knowledge Distillation
Shiu-hong Kao*, Jierun Chen*, S.-H. Gary Chan
Preprint, 2023 pdf
We propose StableKD, a simple and efficient Knowledge Distillation framework that attains higher accuracy using fewer training epochs and less data.
Run, Don't Walk: Chasing Higher FLOPS for Faster Neural Networks Jierun Chen, Shiu-hong Kao, Hao He, Weipeng Zhuo, Song Wen, Chul-Ho Lee, S.-H. Gary Chan
CVPR, 2023 pdf /
code
We propose a simple yet fast and effective partial convolution (PConv),
as well as a latency-efficient family of architectures called FasterNet.
TVConv: Efficient Translation Variant Convolution for Layout-Aware Visual Processing Jierun Chen, Tianlang He, Weipeng Zhuo, Li Ma, Sangtae Ha, S.-H. Gary Chan
CVPR, 2022 pdf /
video /
code
TVConv works more computation-efficient than regular convolution when dealing with layout-specific
tasks, e.g., face recognition.
Joint Demosaicking and Denoising in the Wild: The Case of Training Under Ground Truth Uncertainty Jierun Chen, Song Wen, S.-H. Gary Chan
AAAI, 2021 pdf /
video
We consider the ground truth uncertainty for joint demosaicking and denoising in the wild, which provides better restoration result and interpretability.
Target-agnostic Source-free Domain Adaptation for Regression Tasks
Tianlang He, Zhiqiu Xia, Jierun Chen, Haoliang Li, S.-H. Gary Chan
ICDE, 2024 pdf
We propose TASFAR, a novel target-agnostic source-free domain adaptation method for regression tasks.
We propose CP-NeRF to enable training a one-for-all NeRF across diverse scenes.
FIS-ONE: Floor Identification System with One Label for Crowdsourced RF Signals
Weipeng Zhuo, Ka Ho Chiu, Jierun Chen, Ziqi Zhao, S.-H. Gary Chan, Sangtae Ha, Chul-Ho Lee
ICDCS, 2023 pdf /
code
We design a floor identification system for crowdsourced RF signals in a building using only one labeled data sample
from the bottom floor.
Semi-supervised Learning with Network Embedding on Ambient RF Signals for Geofencing Services
Weipeng Zhuo, Ka Ho Chiu, Jierun Chen, Jiajie Tan, Edmund Sumpena, Sangtae Ha, S.-H. Gary Chan, Chul-Ho Lee
ICDE, 2023 pdf /
code
We develop a practical geofencing system, solely based on ambient radio frequency (RF) signals,
to enable applications like elderly care, dementia antiwandering, pandemic control, etc.
