A Metamorphic Testing Framework for Verification and Validation of Unsupervised Sensor Grouping in Smart Spaces via Spectral Clustering

Fahim Ahmed Irfan, Md Asif tanvir, Md Abdur Rahman Fahad, Razib Iqbal

In this paper, we propose a metamorphic testing approach for verifying a novel sensor grouping technique in smart spaces. The technique employs a spectral clustering algorithm with graph-based feature representations derived from time-series data. Our approach defines ten metamorphic relations addressing verification and validation perspectives.

Towards Human-Centric Smart Homes: Modeling Sensor-Actuator Interactions with Deep Learning

Md Abdur Rahman Fahad, Razib Iqbal

In this paper, we propose a novel data-driven approach for learning sensor-actuator activation and deactivation patterns in smart home environments, independent of specific human activities. Our method extracts information on sensor-actuator interactions, which is used to automate the decision making for actuators.
