Quantization

Quantize the weights, biases, and activations of layers to reduced precision scaled integer data types

Use Deep Learning Toolbox™ together with theDeep Learning Toolbox Model Quantization Librarysupport package to reduce the memory footprint and computational requirements of a deep neural network by quantizing the weights, biases, and activations of layers to reduced precision scaled integer data types. You can then generate C/C++, CUDA®, or HDL code from these quantized networks.
