Claim 7:
8. The system for constructing a digital rock according to claim 7, wherein the discriminator network model unit specifically comprises:
a first discriminator loss function subunit, configured to extract N sub-samples from the sample set, and input the N sub-samples into the discriminator network to calculate a first discriminator loss function;
a first discriminator gradient subunit, configured to calculate a first discriminator gradient of each layer of the discriminator network using the first discriminator loss function;
a second discriminator loss function subunit, configured to extract N first fake-digital rock images from the fake sample set, and input the N first fake-digital rock images into the discriminator network to calculate a second discriminator loss function;
a second discriminator gradient subunit, configured to calculate a second discriminator gradient of each layer of the discriminator network using the second discriminator loss function;
a discriminator loss function subunit, configured to add the first discriminator loss function and the second discriminator loss function to obtain the discriminator loss function; and
a discriminator network model subunit, configured to optimize the discriminator loss function using the first discriminator gradient, the second discriminator gradient, and a mini-batch gradient descent algorithm to obtain optimal discriminator network parameters, and obtain the discriminator network model based on the optimal discriminator network parameters, wherein the discriminator network parameters are a weight and bias of each layer of the discriminator network.
