Yaxuan Wang
(王雅璇)
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.
