Comparison_between_LDA_and_NMF

Comments

No complaints here, looks nice and is written in a clear and understandable manner. One minor thing: Your hypothesis (or rather motivation) is kind of short. Why are you comparing these two approaches? And what other current work is there in scientific literature? Surely, people must have gone further than LDA and matrix factorization in the field of topic inference.

   The formalism (definitions, mathematics) was well chosen to make the page easier to understand. 5
   The abstract is a concise and clear summary. 5 
   There were appropriate (original) examples that helped make the topic clear. 5
   There was appropriate use of (pseudo-) code. 5
   It had a good coverage of representations, semantics, inference and learning (as appropriate for the topic). 5
   It is correct.5
   It was neither too short nor too long for the topic. 5
   It was an appropriate unit for a page (it shouldn't be split into different topics or merged with another page). 5
