Deep Learning Model Optimization

Key Optimization Technologies

  1. Model structure optimization
    • Model Compression
      • Pruning: Reduce model size by removing less important neurons or weights.
      • Quantization: Convert 32-bit floating point operations to 16-bit or 8-bit integers to reduce the model size and computation amount.
    • Lightweight model design
      • Design of lightweight neural network structures.
      • The balance between accuracy and speed through hierarchical design.
  2. Hardware Optimization
    • GPU/TPU Utilization
      • Using hardware acceleration libraries.
    • Edge device optimization
