Adaptive Quantization with Mixed-Precision Based on Low-Cost Proxy

ICASSP 2024accepted

It is critical to deploy complicated neural network models on hardware with limited resources. This paper proposes a novel model quantization method, named the Low-Cost Proxy-Based Adaptive Mixed-Precision Model Quantization (LCPAQ), which contains three key modules. The hardware-aware module is des…
