Discriminative model:

• The conditional probability of class label on data (posterior) $p(C_k\mid x)$

Generative models:

• Likelihood $p(x\mid C_k)$
• Sample from the likelihood to generate data
• With latent variables $z$ and some neural network parameters $\theta$: $P(x,z\mid \theta) = p(x\mid z, \theta)p(z)$
