  • Publication number: 20210326710
    Abstract: Methods and apparatuses of neural network model compression/decompression are described. In some examples, an apparatus of neural network model decompression includes receiving circuitry and processing circuitry. The processing circuitry can be configured to receive a dependent quantization enabling flag from a bitstream of a compressed representation of a neural network. The dependent quantization enabling flag can indicate whether a dependent quantization method is applied to model parameters of the neural network. The model parameters of the neural network can be reconstructed based on the dependent quantization method in response to the dependent quantization enabling flag indicating the dependent quantization method is used for encoding the model parameters of the neural network.
