Abstract:

Many of the Internet of Things (IoT) applications (e.g., smart buildings, health care, industrial monitoring) rely on indoor localization. Indoor positioning sensor-derived data is usually full of anomalies that negatively affect the localization accuracy. The current paper is a framework that integrates Machine Learning (ML) and Deep Learning (DL) localization models with an outlier-detecting preprocessing step based on the Isolation Forests. Experiments on one of the UCI Wi-Fi RSS datasets reveal that an outlier detection application can improve the accuracy of classifications by up to 2.7-10.1 percent and decrease localization error by up to 2.2 meters. A hybrid CNN-LSTM model performs best with an accuracy of 97.1 percent and a localization error of 1.52 meters.

Keywords:

Indoor localization, Internet of Things, Outlier detection, Isolation Forest, Machine learning, Deep learning, CNN- LSTM.
