# Diagnostic Generator¶

This model is trained over around 2 millions diagnostics to extract the probability distributions of word bigrams, which are groups of 2 words that appear one after the other. There are more frequent bigrams than others, for example the bigram caries dentinaria is more frequent than caries gingival and using these conditional probabilities we can synthesize new diagnostics that appears to be written by humans. The method used to model this process is a First Order Hidden Markov Model.
