Research Experience

Differentiable Visual-Inertial SLAM
Sep 2022 - Now

AirLab, Robotics Institute

Building a differentiable visual Simultaneous Localization and Mapping (SLAM) system using PyPose. Combining deep learning and self-supervised learning techniques into traditional SLAM system, allowing for self-adaptive performance and improving the robustness of traditional algorithm under challenging environment.

Generated Text Detection
Mar 2023 - Aug 2023

Language Technology Institute

Using language models like BERT and T5 as backbone, built a GPT-generated content detector called "GPT-Sentinel". Reaches 98% accuracy on test dataset and outperform existing content detector by OpenAI and ZeroGPT. Collected a OpenGPTText dataset, a dataset contains 30k human written text from OpenWebText and its corresponding rephrased version by ChatGPT.

Medical Image Segmentation
Dec 2018 - Jan 2020

Guangdong Cardiovascular Institute

Working under prof. Yiyu Shi and Dr. Xiaowei Xu, I proposed an encoder-decoder architecture to perform semantic segmentation on cardiac MRI sequence. By introducing Temporal constraint on segmentation result, the model improved the accuracy by 2% on ACDC Dataset comparing to the baseline model.

Teaching Assistant

  • 2023 Fall, Carnegie Mellon University, 10-701 Introduction to Machine Learning (PhD)
  • 2022 Fall, Carnegie Mellon University, 15-122 Principles of Imperative Programming

Personal Projects

C0 Visualizer on the Cloud

A virtual machine on browser that executes the C0 bytecode and provides visualization / debugging tools like breakpoint and memory graph.

Now deployed as course infrastructure for 15-122 Principles of Imperative programming and is used by 500+ students every semester.


The Fences

The Fence is a place where CMU students can express their thought and ideas freely. Using webGL and webRTC, we built an online AR application that allows everyone to turn everywhere in reality into a draw board without limit.
