1. Topic model distributions

2. LDA
A common Bayesian topic modeling approach is
LDA (Latent Dirichlet Allocation)
Latent for hidden topic distributions
Dirichlet for an infinite measures probability distribution
Allocation for allocating words to topic distributions
3. Dirichlet distributions
Dirichlet distributions and infinite measures are the basis for the
LDA algorithm for topic modeling.
