OpenGrm NGram News

OpenGrm NGram - Release 1.3 (compatible with OpenFst 1.6.5)

  • Templated Arc to provide new hist-arc counting, supporting fractional count based Katz backoff models. (1.3.0)
  • Updated error handling. (1.3.0)
  • Updated code to better conform to Google C++ guidelines. (1.3.0)
  • Added Bayesian model merging. (1.3.0)
  • Some re-factoring of functions to improve efficiency, particularly those for distributed training, such as ngram-complete and ngram-split. (1.3.0)
  • Updated unit tests to run more quickly and to be less bash-specific. (1.3.0)
  • Updated unit test scripts to use random file names and directories, to avoid collisions with multiple processes. (1.3.1)
  • Fixed ill-formatting in error handling. (1.3.1)
  • Improved reading of large files of ngram counts with ngramread. (1.3.1)
  • Compatibility with OpenFst version 1.6.0 (1.3.2)
  • Substantial rewrite of the ngram-marginalize methods. The algorithm now has improved efficiency and stability, and no longer needs the --iteration flag. (1.3.3)
  • Minor floating point stability and error handling updates. (1.3.3)
  • Update to ngram-shrink methods to allow specification of a minimum order to prune. (1.3.3)
  • Some changes to container types, following usage recommendations. (1.3.3)

OpenGrm NGram - Release 1.2

  • Port to C++11 (1.2.0)
  • Port to C++11 addenda (1.2.1)
  • Compatability with OpenFst version 1.5.1 (1.2.2)

OpenGrm NGram - Release 1.1

  • Substantially refactored code to allow for easy distributed model building.
  • Included a 'convenience' shell script bin/ that runs some common pipelines of commands, e.g., from text file to pruned language model. Shell script provides illustration of distributed model building utilities.
  • Functions to re-estimate smoothed n-gram models to impose marginal distribution constraints.

OpenGrm NGram - Release 1.0

  • Initial public release
