01

Edge Intelligence

Edge AI performs inference near the source of data rather than sending every observation to a remote server. This can reduce latency, bandwidth use, and dependence on network availability.

02

Embedded AI Constraints

  • Limited RAM.
  • Limited flash/storage.
  • Restricted compute throughput.
  • Energy constraints.
  • Thermal limits.
  • Real-time latency requirements.
  • Intermittent connectivity.

03

Model Optimization

  • Quantization reduces numerical precision.
  • Pruning removes selected parameters or structures.
  • Knowledge distillation transfers behavior to smaller models.
  • Architecture search can optimize models for target hardware.
  • Hardware accelerators can execute neural-network operations efficiently.

04

Applications

  • Visual inspection.
  • Wake-word detection.
  • Predictive maintenance.
  • Gesture recognition.
  • Robotic perception.
  • Sensor anomaly detection.
  • Wearable intelligence.
  • Autonomous devices.
