What is Edge AI?

Edge AI refers to the deployment of artificial intelligence algorithms and models directly on edge devices—hardware that exists at or near the data source (e.g., mobile phones, wearables, industrial sensors, or smart cameras). This means that data is processed locally rather than being sent to distant cloud servers.

✅ Key Characteristics:

• Local data processing (reduces latency)

• Offline capability

• Improved privacy and compliance

• Energy and bandwidth-efficient

How Edge AI Works

Here’s how a typical Edge AI workflow functions:

1. Data Collection: Edge devices collect real-time input via sensors, cameras, or microphones.

2. On-Device Processing: An AI model, optimized for the device, processes the data locally.

3. Real-Time Decision Making: The device acts on the AI output (e.g., send an alert, trigger an actuator, generate content).

4. Cloud Sync (Optional): Relevant results or insights are sent to the cloud for storage, analysis, or further coordination.
