Changelog

[Unreleased]

This is a serialization-breaking release due to the switch to HPPC, which affects feature alphabets.

Added

  • Nonnegative Matrix Factorization
  • Word embeddings (word2vec clone)
  • PagedInstanceList supports iteration correctly
  • lebiathan added stratified sampling of InstanceList
  • This file!

Changed

  • The primitive collections library (for example mapping String to int) has been changed from GNU trove to Carrotlabs HPPC. This change removes all GNU dependencies.
  • The license has been changed from CPL to Apache.
  • Use of VMID for unique identifier for serialized objects. (Breaks serialization!)
  • Many small fixes suggested by ErrorProne.
  • Unneeded imports removed.

Removed

  • The Matrix2 class has been removed.
  • GRMM has been moved to a separate package.

Fixed

  • Te Rutherford fixed a bug where non-String instance IDs were being cast as Strings.

[2.0.8] - 2016-05-03

Changed

  • The default format for document-topic proportions now prints values for all topics in order. The earlier file format (sparse listing of topic/proportion) can be restored using command line options.
