Towards Ubiquitous IoT Sensing: From Low-Cost Devices to Highly-Generalizable Models
PhD Thesis Proposal Defence Title: "Towards Ubiquitous IoT Sensing: From Low-Cost Devices to Highly-Generalizable Models" by Mr. Yinan ZHU Abstract: Internet of Things (IoT) sensing has enabled numerous smart applications, yet still fails to reach full ubiquity, due to two core challenges: (i) Cost: precise sensing always relies on expensive professional devices, impeding large-scale deployment, while commercial low-cost devices have limited sensing granularity; (ii) Generalizability: cross-domain adaptability is severely hindered by complex domain shifts, such as device deployment and environmental gaps. This proposal addresses these two challenges on four typical applications, with innovative research attempts. The first two attempts develop algorithms to enhance the resolutions of low-cost sensors: layout features utilization for radio-frequency identification tag groups and task-oriented spectral reconstruction for multispectral cameras, thus succeeding high-cost sensors. The last two attempts explore feature-wise optimization for dataset-level domain generalization: feature distribution alignment with source-resemble target-domain data selection and generalizable semantic-related feature extraction across domains with large multimodal models. Overall, our attempts advance IoT sensing ubiquity with notable cost reduction and generalizability gain.
