About & Research Profile
Yin-Chen Chen
Networked Sensing × Real-world Machine Learning
I am a lecturer, systems engineer, and founder working at the intersection of networked sensing and real-world machine learning. My academic background began in wireless sensor networks and data mining at National Taiwan University. Since 2015, I have designed and operated a longitudinal residential sensing platform across approximately 95 occupied homes.
My doctoral research aims to develop learning methods that remain reliable under cross-home heterogeneity, limited supervision, sensor changes, and long-term distribution shift. A central aspect of my work is to connect machine-learning methods with an explicit understanding of how real-world sensing data are generated and how they change through deployment, device replacement, maintenance, and environmental variation.
Current Research Platform
Residential Sensing Testbed
A longitudinal IoT platform deployed across approximately 95 occupied rental homes, collecting minute-level electrical and environmental measurements. The platform captures real-world heterogeneity arising from differences in building conditions, sensing configurations, occupant behavior, device replacement, missing observations, and long-term operational change.
It serves as a testbed for studying robust learning under distribution shift, limited supervision, and non-stationary data streams.
Research Questions
- How can models generalize across heterogeneous homes, devices, and sensing configurations?
- How can reliable learning be achieved when labels are sparse, delayed, or incomplete?
- How can sensing and learning systems detect and adapt to long-term operational, behavioral, and environmental changes?
