I am a first-year master student in the Robotics Institute at Carnegie Mellon University, working with Prof.Fernando De La Torre and Dr.Joseph K J on evaluation for vision language models.
During my undergrad, I worked with Prof.Huazhe Xu at Tsinghua University on reinforcement learning. I have also collaborated with Dr.Ruohan Zhang at Prof.Jiajun Wu’s Lab at Stanford University on Human-robot interaction. I also spent a summer doing internship at Microsoft WebXT group, Bing Ads team.

- Our paper “The Origin of CBRAM With High Linearity, ON/OFF Ratio, and State Number for Neuromorphic Computing” is accpeted at IEEE-TED, 2021
- Robot Learning with Text-to-Image Generation Models
- Explore the possibility of utilizing the knowledge embedded in pre-trained text2image diffusion models to provide visual guidance for robot learning, without any expert demonstrations or human-designed reward functions.
- Propose a pipeline using image editing techniques to generate visual goals for example-based visual RL, and experiments in simulation and real-world validates the effectiveness of the proposed method.
- Dual Representation for Robot Learning under Human Guidance
- Focus on designing sample-efficient preference learning algorithms that can achieve high performance in both oracle and human experiments.
- Incorporate scene graph as a high-level abstraction representation to facilitate better query selection algorithms in preference learning, which lead to SOTA performance in reward estimation.
- Concurrent Multi-task Learning
- Come up with a new task setting, “concurrent multi-task learning”, where the demonstrator demonstrates multiple tasks in a single demonstration, and the algorithm tries to learn all separate tasks with these “concurrent” demonstrations.
- Propose a EM-based Neural Network learning algorithm that can effectively learns separate tasks without requiring extra labels.
- Neuromorphic Computing
- Explore the origin of CBRAM with High Linearity, ON/OFF Ratio, and State Number, which are crucial for a successful neuromorphic computation network(such as deep-learning neural networks) built from these CBRAMs as neurons.
- Build a Powerful Neural Network using this CBRAM model as neurons which can solve the MNIST classification problem with SOTA performance(92%) compared to previous neuromorphic computation networks(80%).
