How to retrieve documents according to their topic about corex_topic HOT 2 CLOSED

There's a couple different ways you can get the documents for each topic. You could use the p_y_given_x attribute or log_p_y_given_x attributes to rank which documents are most probable for each topic. You could also get a binary classification of each document in each topic from labels (which applies a softmax from p_y_given_x).

You can also use log_z to rank which documents are "explained" the most by each topic according to pointwise total correlation. If you're looking something simple tough labels or p_y_given_x will probably be enough. Note, CorEx is a discriminative model, which means that CorEx estimates the probability a document belongs to a topic separately for each topic and the probabilities don't have to add up to 1.
