Other forms of generative models

While we've only covered two types of generative model, there are many different types that you may encounter in the literature. The following chart is not exhaustive, but does provide a general overview of the types of generative models out there:

Let's break this down: 

• Explicit density models: Model our data directly from a probability distribution. We explicitly define the probability and solve for it
• Implicit density models: Learn to sample from a probability distribution without defining what that distribution is

Within explicit density models, we have tractable density models and approximate density ...
