• New features
  • Major features of Topic Model Viewer tomotopy.viewer.open_viewer() are ready now.
  • tomotopy.LDAModel.get_hash() is added. You can get 128bit hash value of the model.
  • Add an argument ngram_list to tomotopy.utils.SimpleTokenizer.
• Bug fixes
  • Fixed inconsistent spans bug after Corpus.concat_ngrams is called.
  • Optimized the bottleneck of tomotopy.LDAModel.load() and tomotopy.LDAModel.save() and improved its speed more than 10 times.

• New features
  • Added Topic Model Viewer tomotopy.viewer.open_viewer()
  • Optimized the performance of tomotopy.utils.Corpus.process()
• Bug fixes
  • Document.span now returns the ranges in character unit, not in byte unit.

• New features
  • Added some convenience features to tomotopy.LDAModel.train and tomotopy.LDAModel.set_word_prior.
  • LDAModel.train now has new arguments callback, callback_interval and show_progres to monitor the training progress.
  • LDAModel.set_word_prior now can accept Dict[int, float] type as its argument prior.

• New features
  • Added support for Linux ARM64 architecture.

• New features
  • Added support for macOS ARM64 architecture.
  • Added support for Python3.11
• Bug fixes
  • Fixed an issue where tomotopy.Document.get_sub_topic_dist() raises a bad argument exception.
  • Fixed an issue where exception raising sometimes causes crashes.

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().

• An issue where calling convert_to_lda of tomotopy.HDPModel with min_cf > 0, min_df > 0 or rm_top > 0 causes a crash has been fixed.
• A new argument from_pseudo_doc is added to tomotopy.Document.get_topics and tomotopy.Document.get_topic_dist.
  This argument is only valid for documents of PTModel, it enables to control a source for computing topic distribution.
• A default value for argument p of tomotopy.PTModel has been changed. The new default value is k * 10.
• Using documents generated by make_doc without calling infer doesn't cause a crash anymore, but just print warning messages.
• An issue where the internal C++ code isn't compiled at clang c++17 environment has been fixed.

• An issue where tomotopy.LDAModel.set_word_prior() causes a crash has been fixed.
• Now tomotopy.LDAModel.perplexity and tomotopy.LDAModel.ll_per_word return the accurate value when TermWeight is not ONE.
• tomotopy.LDAModel.used_vocab_weighted_freq was added, which returns term-weighted frequencies of words.
• Now tomotopy.LDAModel.summary() shows not only the entropy of words, but also the entropy of term-weighted words.

• Now tomotopy.DMRModel and tomotopy.GDMRModel support multiple values of metadata (see https://github.com/bab2min/tomotopy/blob/main/examples/dmr_multi_label.py )
• The performance of tomotopy.GDMRModel was improved.
• A copy() method has been added for all topic models to do a deep copy.
• An issue was fixed where words that are excluded from training (by min_cf, min_df) have incorrect topic id. Now all excluded words have -1 as topic id.
• Now all exceptions and warnings that generated by tomotopy follow standard Python types.
• Compiler requirements have been raised to C++14.

• A critical bug of asymmetric alphas was fixed. Due to this bug, version 0.11.0 has been removed from releases.
