Knowledge Distillation
What is Knowledge Distillation?
Knowledge Distillation is a machine learning technique where a large, complex AI model (teacher) transfers its knowledge to a smaller, faster model (student) optimized for edge devices. This enables advanced AI capabilities on resource-constrained hardware without sacrificing performance.
Knowledge Distillation involves creating compact AI models that mimic larger models’ behavior, ensuring high accuracy while using less memory and computational power—critical for Edge AI applications.
Why Is It Used?
To deploy advanced AI models on edge devices with limited hardware.
To reduce latency and energy consumption in real-time applications.
To maintain high model accuracy while optimizing resource usage.
How Is It Used?
Train a large teacher model on extensive datasets.
Transfer the learned patterns, predictions, and behaviors to a smaller student model.
Deploy the student model on edge devices such as IoT sensors, drones, and smartphones.
Types of Knowledge Distillation
Offline Distillation: Knowledge is transferred after the teacher model is fully trained.
Online Distillation: Teacher and student models learn simultaneously during training.
Self-Distillation: A single model refines its own predictions to improve efficiency.
Benefits of Knowledge Distillation
Resource Efficiency: Smaller models require less memory and computation.
Faster Inference: Real-time AI on edge devices without cloud dependency.
Energy Savings: Optimized for battery-powered or low-power hardware.
Scalability: Enables deployment across diverse IoT and edge environments.
