training process regarding the generator and discriminator's
loss scores; the generator tries to reduce the loss function as
much as possible, which may fool a discriminator. CGAN
generated 2814 COVID-19 images. The number of epochs
was decided depending on the resolution of the generated
images, the quality of the produced images increased over
500 epochs and increased gradually until could generate
high-resolution images. CGAN was trained for many
iterations.
