5. Generative models

A generative model is an algorithm that generates samples according to the same probability law as the data provided in the initial database, but without this probability law necessarily being explicitly described.

5.1 Variable autoencoders

We have seen how deep learning methods can be used to perform dimensionality reduction using auto-encoders by associating with each object x i in a very high-dimensional space a latent representation h i = f θ (x), where f θ is a neural network, and by optimizing the parameters θ of f θ and...
