Tinkering
DIY CNC Laser Engraver
This is one of my works carried out during the second grade of high school, just for making engraved gifts for friends.
Mar 2015 at Fuzhou No.1 High School, Fuzhou nRF24L01 Wireless Messenger
Made just for fun. Soldering was done mostly by my roommate BI8CSY.
Dec 2016 at UESTC, Chengdu Satellite Tracker
A project carried out with the my HAM friend BI8CSY. Should have been built into a self-adaptive rotator but left unfinished due to covid.
Oct 2019 at UESTC, Chengdu
Electronic Design Competitions
Remote Frequency Response Analyzer
A project during National Undergraduate Electronic Design Contest, designed and manufactured with Fu in 4 days & 3 nights.
Aug 2017 at UESTC, Chengdu Smart Home Monitor with Gesture Recognition
A project for a contest, designed and assembled with my teammate Hsury.
Mar 2017 at UESTC, Chengdu Portable Scientific Calculator based on AVR MCU

Dissertation & Research
Collective Matrix Factorization
Expanding Boolean MF to the joint-factorization of multiple binary tables.
Acoustic Sensing for Indoor Localization
A joint work with NCS that applies ultrasound fingerprinting to indoor localization.
Multi-agent Reinforcement Learning for UAV Collision Avoidance
An EE5001 project. The main contribution is the development of an OpenAI Gym environment that is friendly for applying multi-agent RL algorithms.
HEVC Optimization using CNNs
Using convolutional neural networks to accelerate the classification of block tree division.
