Forward Sampling
Learn the basics of forward sampling and how we can prepare the trained QBN.
We'll cover the following...
In the previous chapter Bayesian Inference, we learned how to apply a variational method to learn a hidden variable. Variational methods approximate the distribution of a hidden variable analytically.
Sampling-based methods work differently. Instead of calculating the hidden distribution, they approximate it empirically. The principle is straightforward. These methods repeatedly select an instance and ...
