Description

When I print out topic_info from the model (with get_topic_info()), there are a bunch of files in topic -1 which I want to filter out. I was going to do this by creating a mask with the topic_distrubution you get when running approximate_distribution() but the distribution_matrix seems to have 1 less topic columns when looking at the shape of topic_distribution. How can I find the documents that are "assigned" to topic -1?

Research direction

Start with the get_topic_info() and approximate_distribution() entry points described in the issue, and compare how topic -1 is represented with the distribution_matrix columns. Check the relevant BERTopic documentation and implementation to determine how documents assigned to topic -1 can be identified; done means the mapping and filtering approach is clearly documented.
