Edge AI and TinyML
Deploying ML models to edge devices — from model optimization (quantization, pruning) through TensorFlow Lite Micro, ONNX Runtime, and deployment on MCUs and edge hardware.
When to Use
- Running ML models on resource-constrained devices
- Reducing cloud dependency and latency
- Privacy-preserving on-device inference
- IoT sensor data processing at the edge

Verification Checklist
- Quantization method chosen (INT8, FP16) for target hardware
- Model fits within edge device memory (RAM + flash)
- Inference latency acceptable for use case
- Accuracy validated post-quantization
- Hardware support verified (TFLite Micro, ONNX Runtime, or vendor SDK)
- Power consumption measured (battery-powered devices)
- OTA update mechanism for model updates
