Qiucheng Wu

I am a 1st year Ph.D. student in Computer Science at University of California, Santa Barbara, under supervision of Prof. Shiyu Chang. I received my bachelor and master's degrees from University of Michigan College of Engineering. I also receivied another bachelor degree from and Shanghai Jiao Tong University UM-SJTU Joint Institute.

I am interested in multimodality problems in Artificial Intelligence. Preivous to my Ph.D. study, my interests span across natural language processing, computer vision, reinforcement learning and data mining. Some of my projects and publications related to these fields are demonstrated below.

Currently, I focus on beyond the state-of-the-art image deblurring methods.

Comparison between Human Attention and Linguistic Justifications on Images
Qiucheng Wu
Natural Language Processing (EECS 595, FA 19) Course Project, full points (10/10)

In this work, we compare human attention and linguistic justificaiton on Visual Question Answering (VQA) problems. We collect the regions that human focuses on in different images, and we also collect the textual answers, representing them in the images. Finally, we compare two regions in the images to study their relations.


Landmark Recognition in Vision Language Navigation
Qiucheng Wu, Naihao Deng, Yin Lin
Situated Language Processing in Emboddied Agents (EECS 598, WN 20) Course Project

In this work, we consider the visual language navigation (VLN) problem by examine if the agents can recognize and reach the intermediate landmarks in the whole path. This reveals agents' ability to ground intermediate landmarks with visual information all along the way.

Graph Two-sample Testing with Node Embeddings
Qiucheng Wu, Yuze Lou, Shucheng Zhong and Jiaxin Wang
Advanced Data Mining (EECS 576, FA 19) Course Project, full points (40/40)

In this work, we propose a novel method to solve graph two- sample testing problem by combining node embedding methods and statistical two-sample test methods. We have evaluated our method with multiple node embedding methods and conduct experiments on both synthetic datasets and real datasets.


DataSifterText: Partially Synthetic Text Generation for Sensitive Clinical Notes
Nina Zhou, Qiucheng Wu, Zewen Wu, Simeone Marino, and Ivo Dinov
Submitted to Journal of the American Medical Informatics Association, 2020

In this work, we propose the DataSifter-Text to protect privacy of sensitive textual dataset. The DataSifter-Text protects the data by obfuscating identifiable information in the dataset. We analyze the trade-off between obfuscation and preserving utilities of the data, and DataSifter-Text effectively balances between privacy and utility.

DataSifter: Statistical Obfuscation of Electronic Health Records and Other Sensitive Datasets
Marino, S, Zhou, N, Zhao, Yi, Wang, L, Wu Q, and Dinov,
Journal of Statistical Computation and Simulation, 2018

This is the previous work of DataSifter-Text. In this work, we propose the DataSifter to obfuscate sensitivie dataset while preserve the utility for other researches. I discuss and implement the obfuscation function in R-cpp.

Working Experience
Fitly Inc.
Machine Learning Intern
Nov. 2019 - Apr. 2020

In this internship, I was responsible for designing a personalized model to provide more accurate food classification results for users. My code is now deployed in the real product.
Intel Akraino: Edge Cloud Game Architecture
Undergraduate Capstone Team Gold Prize
UM-SJTU Joint Institute, Shanghai Jiao Tong University, August 2019

In this capstone project, we designed a framework to boost web communications between terminal devices and servers by introducing edge servers. We use kubernets to organize edge servers as different containers. The edge servers are responsible for computing and sending information to terminal devices, leading to more efficient performance.
