• Industrial Internet of Things (IIoT)
• Machine Learning
• Data Science

Background:

• Industrial Internet of Things (IIoT) devices generate vast amounts of spatiotemporally correlated and heterogeneous sensor data.
• Current anomaly detection algorithms face challenges processing this complex, large-scale data.
• The need for efficient and accurate anomaly detection in IIoT facilities is critical.

Purpose of the Study:
