I am a PhD student in UC Berkeley Vision Science, with a focus on computer vision. I am currently advised by Prof. Stella Yu. Previously I was a research intern at Sensetime. I received my B.E in Electronic Engineering from XJTU in 2018, where I worked with Prof. Jinjun Wang at Institute of Artificial Intelligence and Robotics.

A Comparison of Visual Features used by Humans and Machines to Classify Wildlife

BiorXiv 2018. [paper]

This work aims to interpret the concepts behind the convolutional neural networks (CNNs) in classifying wildlife.

Joint Embedding and Classification for SAR Target Recognition
Jiayun Wang, Patrick Virtue and Stella X. Yu.
arXiv 2017. [paper]

This work aims to address the overfitting problem in remote sensing image classification.

Point to Set Similarity Based Deep Feature Learning for Person Re-identification
Sanping Zhou, Jinjun Wang, Jiayun Wang, Yihong Gong and Nanning Zheng.
CVPR 2017. [paper] [code]

This work presents a novel metric learning method based on P2S similarity comparison for person re-identification.

Deep Ranking Model by Large Adaptive Margin Learning for Person Re-identification
Jiayun Wang, Sanping Zhou, Jinjun Wang and Qiqi Hou.
Pattern Recognition. [paper] [arxiv] [code]

This work designs a dynamically adaptive loss function to overcome the drawbacks of conventional loss functions for person re-identification.

Hierarchical Model for Long-term Video Prediction
Peter J. Wang, Zhongxia Yan and Jeffrey Zhang.
CS 280 (Computer Vision) Final Project. [demo] [report] [slides] [code]

We use a hierarchical approach for long-term video prediction, aiming at estimating high-level structure in the input frame first, then predicting how that structure grows in the future.

Two-lens Camera Trap System
Peter J. Wang, Qiuyu Zhang, Jingwen Zhu and Zhongqi Miao.
CS 294-127 (Computational Imaging) Final Project. [paper] [slides]

We designed and implemented a stereo camera system which is able to estimate the height and moving direction of the animal.

Object Recognizing Surface Organizer
Loren Jiang, Peter J. Wang, Qiuyu Zhang and Jingwen Zhu.
EECS 106A (Robotics) Final Project. [website] [code: available on request]

Our robotic system (Baxter) is able to recognize a number unique objects on the workspace and move them to their desired positions with relatively low rates of failure.
