Yaxuan Wang


I am an undergraduate in Computer Science and Technology (Top-notch Program, a class of 15 elite students selected from 400+) of Sichuan University and will graduate in June 2023. My current advisor is teacher Qijun Zhao from the School of Computer Science.

I am interested in building intelligent agents or models that can learn from various data sources (e.g., images, audio, and text) and automate decision-making processes in uncertain environments to solve multiple real-world tasks.

Overall GPA:3.85/4  /  Average Score 91.43/100  /  IELTS 7.0

My research interests currently include:

  • Trustworthy Machine Learning, especially Fairness, Interpretability and Robustness
  • Reinforcement Learning
  • Representation Learning & Learning from Dynamic and Noisy Data
  • My research lies in the broad area of machine learning and data science and I am open to specific issues. I love the process of giving machines the intelligence to address social and healthcare problems.

  • Recent Research

  • Weakly Supervised Learning combined with Temporal Anomaly Detection
  • With Prof Yang Liu (University of California, Santa Cruz) and Staff Engineer Qingsong Wen (DAMO Academy)

  • A novel anomaly detection approach is proposed based on the informative representation. (More details in the future paper)
  • Responsible for the design of models and implementation of algorithms.
  • Our method achieves satisfactory results in all selected time-series datasets compared to the previous model.
  • Currently working on a paper that is expected to be submitted to IJCAI 2023.

  • Research on Urban Safety Perception using Reinforcement Learning and Inverse Reinforcement Learning
  • With Prof Qijun Zhao (Sichuan University)

  • We aim to leverage reinforcement learning-based decision framework to obtain human-like safety perceptions and use inverse reinforcement learning (IRL) to recover the reward function that can explain the evaluation pattern and help experts quantitatively analyze perceptual features.
  • Experimental results using our crowdsourced dataset showed satisfactory prediction performance (at least 3% improvement in F1 score) and excellent visual interpretability. It also showed that IRL has promising prospects in this field.
  • I was one of the main executors of this project, and we completed the writing and publication of two papers (one as first author, the other as a co-author).

  • Autonomous Robot Shooting and Movement in Specific Maps
  • With Prof Jiancheng Lv Prof Qijun Zhao (Sichuan University)

  • Based on visual perception and cost map, we used behaviour tree to realize intelligent decision-making of the automatic robot, which can move and shoot on a specific map.
  • Responsible for the construction of the robot decision-making framework. Also as the project leader to control the research progress and the funding application.
  • Our project won the ICRA RMUA International Third Prize.
