0.12.3

New features

• Now, inserting an empty document using tomotopy.LDAModel.add_doc() just ignores it instead of raising an exception. If the newly added argument ignore_empty_words is set to False, an exception is raised as before. (#161)
• tomotopy.HDPModel.purge_dead_topics() method is added to remove non-live topics from the model. (#152)

Bug fixes

• Fixed an issue that prevents setting user defined values for nuSq in tomotopy.SLDAModel (by @jucendrero). (#174)
• Fixed an issue where tomotopy.utils.Coherence did not work for tomotopy.DTModel. (#164)
• Fixed an issue that often crashed when calling make_doc() before calling train(). (#166)
• Resolved the problem that the results of tomotopy.DMRModel and tomotopy.GDMRModel are different even when the seed is fixed. (#63)
• The parameter optimization process of tomotopy.DMRModel and tomotopy.GDMRModel has been improved.
• Fixed an issue that sometimes crashed when calling tomotopy.PTModel.copy().
