DATA PROCESSING DEVICE, DATA PROCESSING SYSTEM, AND DATA PROCESSING METHOD

The present invention is provided with: a data processing unit (10) for learning a neural network; and an encoding unit (11) for generating encoded data in which model header information for identifying models of the neural network, layer header information for identifying layers of the neural network, and edge weight information in units of layers are encoded, wherein the encoding unit (11) encodes layer structure information indicating a layer structure of the neural network and a new layer flag indicating whether each of the layers to be encoded is a new layer or an update of a layer of a reference model.
