cosinePCA: Calculate LDAvis Topic Cosine Similarity
In sailuh/topicflowr: Topic Flow
View source: R/visualization.R
Description
This function is used as a replacement to 'jsPCA' in LDAVis package function createJSON, as
the default can't handle words with probability 0. This also ensures consistency to the different
month topics, as it now uses the same cosine similarity instead of symetric Dkl. For more details,
see issue: https://github.com/sailuh/perceive/issues/84
Usage
1
cosinePCA(phi)
Arguments
phi,
as specified in createJSON on LDAvis.
