LDA can be thought of as a clustering algorithm as follows: (1)Topics correspond to cluster centers, and documents correspond to examples (rows) in a dataset. (2)Topics and documents both exist in a feature space, where feature vectors are vectors of word counts (bag of words). (3...

Let's take a closer look at the parameters we want to solve: the topic distribution for each of the M documents (\mathbf \Theta) and the word distribution for each of the K topics (\mathbf \Phi). In order to estimate them, the LDA algorithm makes some assumptions about their prior. ...
