Edge AI Functionalities
1. Anomaly Detection
What it is:
Anomaly detection refers to identifying patterns in data that deviate from the expected behavior. These could be sudden spikes, drops, or subtle changes in how systems perform.
Use in Power/Energy:
In the power industry, anomaly detection is essential for spotting voltage sags, frequency fluctuations, harmonic surges, or sudden transformer overheating — all of which may precede equipment failure or grid instability. Early detection prevents blackouts and improves the reliability of distribution systems.
Use in Industrial Automation:
Factories and plants can experience abnormal behavior due to worn-out machinery or unstable loads. Edge AI detects anomalies in motor current, conveyor torque, or vibration signals, allowing operators to intervene before a breakdown occurs.
Use in Automotive:
In vehicles, anomaly detection helps in identifying early symptoms of sensor failure, abnormal throttle behavior, or inconsistent data on CAN networks. For example, an edge model can flag irregularities in brake pressure sensors before they fail.
Models Used:
Autoencoders, Isolation Forest, One-Class SVM, and LSTM models (for time-series data) are commonly deployed to capture and learn the “normal” behavior and flag deviations in real-time.
2. Pattern Recognition
What it is:
Pattern recognition involves identifying and classifying recurring sequences or structures in data, such as waveform shapes, vibration cycles, or usage profiles.
Use in Power/Energy:
Power analyzers and smart meters use pattern recognition to classify waveforms (e.g., identifying whether the load is inductive or capacitive) or detect harmonic patterns that affect power quality.
Use in Industrial Automation:
Edge AI systems classify machine operation states — distinguishing between “idle,” “under load,” or “fault” modes based on power, torque, or vibration patterns. This is critical for real-time monitoring and efficiency.
Use in Automotive:
Pattern recognition is used to recognize driving behavior (e.g., aggressive acceleration, braking patterns) or mechanical wear (e.g., tire imbalance from vibration signatures). It also helps classify road conditions based on sensor data.
Models Used:
Convolutional Neural Networks (CNN), Multilayer Perceptrons (MLP), and Decision Trees are used for both spatial and time-series patterns, especially where waveform classification is needed.
3. Source Identification

Source identification refers to the process of tracing an observed issue — like a fault, noise, or distortion — back to its origin, whether it’s a specific machine, phase, or subsystem.
Use in Power/Energy:
In power grids, when harmonics or voltage imbalances are detected, edge AI can identify which feeder line or consumer load is responsible. This speeds up maintenance and minimizes service disruption.
Use in Industrial Automation:
When a line vibration or power fluctuation occurs, AI at the edge can pinpoint whether it originated from a specific motor, faulty drive, or overloaded segment — saving hours of manual diagnostics.
