Jiacong Xu

I am a first-year PhD student in Department of Computer Science of Johns Hopkins University and supervised by Prof. Vishal Patel in VIU Lab. Before my PhD study, I worked with Dr. Adam Kortylewski and Prof. Alan L. Yuille as a research intern in CCVL. I completed my M.Sc degree in Texas A&M University and worked closely with Prof. Shankar P. Bhattacharyya and Prof. Zixiang Xiong. Before coming to U.S., I obtained my bachelor degree from University of Science & Technology of China (USTC).

Animal3D: A Comprehensive Dataset of 3D Animal Pose and Shape
Jiacong Xu, Yi Zhang, ..., Alan Yuille, Adam Kortylewski
ICCV, 2023
bibtex | github | Website

Animal3D consists of 3379 images collected from 40 mammal species, high-quality annotations of 26 keypoints, and importantly the pose and shape parameters of the SMAL model. We demonstrate that synthetic pre-training is a viable strategy to boost the model performance.

PIDNet: A Real-time Semantic Segmentation Network Inspired by PID Controllers
Jiacong Xu, Zixiang Xiong, Shankar P. Bhattacharyya
CVPR, 2023
bibtex | github | ranking

SOTA for real-time semantic segmentation. PIDNet possesses three branches to parse the detailed, context and boundary information, respectively, and employs boundary attention to guide the fusion of detailed and context branches in final stage.

Communication-Efficient Design of Learning System for Energy Demand Forecasting of Electrical Vehicles
Jiacong Xu, Riley Kilfoyle, Zixiang Xiong, Ligang Lu
APSIPA ASC, 2023
bibtex | github | Arxiv

In this paper, we propose a communication-efficient time series forecasting model combining the most recent advancements in transformer architec- tures implemented across a geographically dispersed series of EV charging stations and an efficient variant of federated learning (FL) to enable distributed training.

A PID Controller Architecture Inspired Enhancement to the PSO Algorithm
Jiacong Xu, Shankar P. Bhattacharyya
FICC, 2022, Best Student Paper
bibtex

This paper analyzes the connection between the PID controller and the PSO Algorithm and proposes two novel methods, PBSv2 and PAA, to enhance the performance of the PSO algorithm and its variants.

Efficient Tuning of PID Controllers using Swarm-based Optimization Algorithms
Jiacong Xu, Shankar P. Bhattacharyya
ICSC, 2021
bibtex

This paper proposes a approach for online or real-time tuning of PID controllers in applications such as driverless cars or robot manipulators.
