Composing Inverse Functions to Measure Model Fitness

Friday, December 5th, 2008

This articles concerns a method for evaluating the fitness of content topic models and document topic models based on the dissonance between a set of documents and the set of documents generated by composing inverse functions and applying them to the original set of documents. A document generating function is applied to a topic generating function that is applied to the original set of documents. In order to compare topics, one can look at the original set of topics compared to set of topics generated by apply a topic generating function to the documents generated by applying a document generating function to the original set of topics.
