• Bug fixes

Changes in sglOptim version 1.3.5 (2016-12-28)

• Internal code cleanup, bug fixes and refactoring.

Changes in sglOptim version 1.3.0 (2016-09-28)

• Improved documentation and functionality:

  • added functions for extracting number of nonzero features and parameters (feature_stat and parameter_stat)

  • Minor updates and documentation corrections

  • Better handling of R memory protection (fewer PROTECT calls)

  • Hadling of more complex response types

  • subsampling uses foreach and doParallel (showing progressbar no longer supported for subsampling and cross validation)

  • subsampling now supports different lambda sequences for each subsample

• Fixes :

  • fixed sample check bug

  • minor fixes for some numerical computations

• API changes :

  • all lineaer loss classes must set (a sgl::natural) n_variables, whihch will determine the size of the lineaer preditors ( n_samples x n_variables)

  • in class MultiResponse n_groups -> n_responses

Changes in sglOptim version 1.2.0 (2015-09-16)

• Improved flexibility and reliability :

  • added handling of q = 1 cases (each feature has one parameter)

  • correct handling of non penalized parameters when computing lambda.max (fit non penalized parameters before computing critical lambdas)

  • increased speed when optimizing with a high number of groups/classes (> 100)

  • some improvements on error reporting and argument validation

• Fixes :

  • fixed bug related to grouping

  • fixed seval minor bugs

  • fixed startup messages
