Hands-On Deep Learning Algorithms with Python

Discriminator loss

The discriminator loss is given as follows:

First, we will implement the first term, :

D_loss_real = 0.5*tf.reduce_mean(tf.square(D_logits_real-1))

Now we will implement the second term, :

D_loss_fake = 0.5*tf.reduce_mean(tf.square(D_logits_fake))

The final discriminator loss can be written as follows:

D_loss = D_loss_real + D_loss_fake
