- UTD - Advisor: Dr. Yunhui Guo - Jan. 2023 - Present - Led the development of a novel active learning approach to address challenges in active open-set annotation. Our method - Teaching Assistant, 2023 Summer CS Lab - June. 2023 - July. 2023 - Under the guidance of Dr. Yunhui Guo, I was in charge of preparing teaching materials and assignments for students in college level - We simulated the real research process in our teaching: after reading and discussing some of the most advanced articles, the students actively combined different methods based on their advantages and disadvantages to create new ones. These - Projects - Semantic Background Segmentation - An application-oriented project utilizing U-Net Convolutional Neural Network for background detection. The - Extended the project to portrait background detection using the dataset from the Deep Automatic Portrait - Matting project of The Chinese University of Hong Kong. The trained U-Net model successfully detected and replaced the background of portraits based on user input - Hiding Traffic Fingerprints - Collected web traffic data using Wireshark and trained a deep learning classifier in Google Colab to recognize - Bayes, and 90.24% with the J48 tree, demonstrating the potential for mitigating website fingerprinting attacks - Multiplayer Virtual Reality Game - Developed a multiplayer virtual reality game using Unity and the Photon Engine, designed for both iOS and Android platforms. The game, centered around cooking, allows players to interact with in-game objects using - Google Cardboard and a joystick controller
