Variance‐driven security optimisation in industrial IoT sensors

IET Networks, Volume 14, Issue 1, January/December 2025.
The methodology employed in this study adopts a systematic approach to deploying machine learning algorithms for the detection of anomalies in industrial sensor data. Data preprocessing, the first step in the process, ensures that the industrial sensor data is cleaned and prepared for subsequent model training.
