Slides on Topic Modeling – Background, Hyperparameters and common pitfalls

I just uploaded my slides on probabilistic Topic Modeling with LDA that give an overview of the theory, the basic assumptions and prerequisites of LDA and some notes on common pitfalls that often happen when trying out this method for the first time. Furthermore I added a Jupyter Notebook that contains a toy implementation of the Gibbs sampling algorithm for LDA with lots of comments and plots to illustrate each step of the algorithm.
