Discriminator
score
high
dimensional
vector
Larger score means real,
smaller score means fake.
Algorithm
? Initialize generator and discriminator
? In each training iteration:
G
D
Step 1: Fix generator G, and update discriminator D

Discriminator learns to assign high scores to real objects
and low scores to generated objects.
