MODEL CONSTRUCTING METHOD OF NEURAL NETWORK MODEL, MODEL CONSTRUCTING SYSTEM, AND NON-TRANSITORY COMPUTER READABLE STORAGE MEDIUM

A model constructing method for a neural network model applicable for image recognition processing is disclosed. The model constructing method includes the following operation: updating, by a processor, a plurality of connection variables between a plurality of layers of the neural network model, according to a plurality of inputs and a plurality of outputs of the neural network model. The plurality of outputs represent a plurality of image recognition results. The plurality of connection variables represent a plurality of connection intensities between each two of the plurality of layers.
