In Azure ML's LDA module, a standard way of interpreting a topic is extracting top terms with the highest marginal probability. 0 0 5 ∙ Before moving to Jackie's current city of Belchertown, MA, Jackie lived in Florence MA and Springfield MA. By analyzing usage data, these methods un-cover our latent preferences for items (such as articles or movies) In r there is an excellent tm package (which is already pre-installed on AML virtual machine) that contains the LDA facility: This code allows you to see the topics as this multinomial distribution, like in the first image. share, The electronic health record (EHR) provides an unprecedented opportunity... share, We present a hybrid algorithm for Bayesian topic models that combines th... ∙ David Bleitor.
