About Me

I am a Ph.D. student at Dartmouth College, advised by Prof. SouYoung Jin. I focus my research on Video Understanding as it has numerous practical applications that can benefit society in various ways. I am excited to carry out advanced research focused on training sophisticated, trustworthy, and high-quality machine learning models that can better interpret and comprehend the visual world.

Prior to Dartmouth, I earned a Master's degree in Computer Science from Northwestern University (2021), advised by Prof. Nabil Alshurafa, and a B.S. degree in Computer Science from the University of Pittsburgh (2020).

Interactive Active Learning Annotation Tool

  • An interactive annotation software that utilizes active learning to reduce data labeling time and cost. The front-end was created with PyQt5 and pyqtgraph, offering features such as time synchronization and video frame-by-frame rewinding. The back-end, utilizing cv2, sklearn and xgboost, performed data processing, K-means clustering, and clustered entropy active learning.
