I am currently studying at Duke University for a Ph.D. in Electrical and Computer Engineering. My research focuses on Computer Vision, Machine Learning, and Artificial Intelligence. I am a passionate and committed researcher. Now seeking research positions.
Federated Unsupervised Representation Learning
Duke University, Research Advisor: Yiran Chen
Implemented an unsupervised distributed learning framework. Proposed personalized network branches at local clients.
Unsupervised Image Segmentation
Samsung Semiconductor, Research Advisor: Mostafa El-Khamy
Implemented a weakly supervised loss in addition to the cluster loss. Designed a box sampling process for better label continuity in neighboring pixels.
Causal Framework for Generalized Image Representation
Duke University, Research Advisor: Taoyang Chen
Developed causal graphs for image representation learning. Synthesized observational data for validating causal graphs. Implemented experiments to test assumptions. Adapted causal relation to real images to improve the generalization of the representation.
Unsupervised Visual Representation Learning
ABB Inc., Research Advisor: Remus Boca
Representation Learning using a contrastive learning framework. Improved representations by inducing adversarial noise. Verified quality representations on vision downstream tasks.
Positive Unlabeled Learning in Object Detection
Duke University, Research Advisor: Kevin Liang
Verified the performance drop using a popular dataset that has incomplete labels. Improved performance using Positive Unlabeled learning instead of Positive Negative Learning is commonly used. Implemented PU detectors with Faster Regional CNN and Single Shot Detector.
Interpretability and Transfer Learning of Deep Neural Network
Duke University, Research Mentor: Prof. Henry Pfister
Trained deep CNN models with both synthesized and real image datasets and tested them on a real dataset. Utilized Class Activation Mapping to localize multiple objects in images and interpreted the inner mechanism of the network.
Multiple Instance Learning for Training Weakly Supervised Learning Models
Duke University, Research Mentor: Dr. Jordan Malof
Built MI SVM and CNN models to study the underlying relationships between the complexity of a classifier, the positive ratio in a bag, and the accuracy of the classifier.
Prediction of Seizure in EEG and ECG signals
Duke University, Research Mentors: Professor Leslie M. Collins and Dr. Nicholas Czernek
Built feature extractors and reduced dimension with PCA and GA. Trained a model with seizure and non-seizure segments with the Random Forest algorithm.
Maximizing Bit Rate in Cognitive Radio System
Research Mentors: Prof. Mohamed-Slim Alouini and Dr. Osama Amin
Verified simulations of different modulation schemes against their analytical expressions. Derived an analytical expression for error probability of improper signaling of secondary users.
