Tanish Baranwal, Arnab Das, Srihari Varada, Santanu K. Das, Mohammad Rafiqul Haider · 2025
This research proposes a lightweight hybrid approach for anomaly detection in correlated IoT sensor data, combining PCA for fast monitoring and Autoencoders for deeper analysis. Validated on real and simulated data, the method offers high accuracy, faster response, and fewer false positives—ideal for resource-constrained environments.
