# Generative Models for the Web

## Associated units

- Understand the principle methodology for building generative models
- Remember why people are interested in generative models
- Know why descriptive models are needed when evaluating a generative model
- Be aware of one way to create a model for text generation

- Understand how to sample values from an arbitrary probability distribution
- Have seen yet another application of the cumulative distribution function
- Understand that sampling from a distribution is just a coordinate transformation of the uniform distribution

- See that it makes sense to compare statistics
- Understand that comparing statistics is not a well defined task
- Be aware of the fact that very different models could lead to the same statistics

- See that one can always increase the model parameters
- Know that increasing model parameters often yields a more accurate model
- Be aware of the bigram and mixed models as examples for our generative processes
