Geomagnetic Indoor Localization

MAIL: Multi-Scale Attention-Guided Indoor Localization Using Geomagnetic Sequences

Qun Niu, Tao He, Ning Liu, Suining He, Xiaonan Luo, Fan Zhou

Intro: We propose MAIL, a multi-scale attention-guided indoor localization network. Our key contributions are as follows. First, instead of extracting a single holistic feature from an input sequence directly, we design a scale-based feature extraction unit that takes variational anomalies at different scales into consideration. Second, we propose an attention generation scheme that identifies attention values for different scales. Rather than setting fixed numbers, MAIL learns them adaptively with the input sequence, thus increasing its adaptability and generality. Third, guided by attention values, we fuse multi-scale features by paying more attention to prominent ones and estimate current location with the fused feature.
