The module comes with complete + documentation and some examples can + + - Improved svm module: memory consumption has been reduced by 50%, + heuristic to automatically set class weights, possibility to + assign weights to samples (see + :ref:`example_svm_plot_weighted_samples.py` for an example). + + - New :ref:`gaussian_process` module by Vincent Dubourg. This module + also has great documentation and some very neat examples. See + :ref:`example_gaussian_process_plot_gp_regression.py` or + :ref:`example_gaussian_process_plot_gp_probabilistic_classification_after_regression.py` + for a taste of what can be done. + + - It is now possible to use liblinear’s Multi-class SVC (option + multi_class in :class:`linear_model.LinearSVC`) + + - New features and performance improvements of text feature + extraction. + + - Improved sparse matrix support, both in main classes + (:class:`grid_search.GridSearch`) as in modules + scikits.learn.svm.sparse and scikits.learn.linear_model.sparse. + + - Lots of cool new examples and a new section that uses real-world + datasets was created. These include: + :ref:`example_applications_plot_face_recognition.py`, + :ref:`example_applications_plot_species_distribution_modeling.py`, + :ref:`example_applications_svm_gui.py`, + :ref:`example_applications_wikipedia_principal_eigenvector.py` and + others. + + - Faster LARS algorithm. It is now 2x faster than the R version on + worst case and up to 10x times faster on some cases. + + - Faster coordinate descent algorithm. In particular, the full path + version of lasso (:func:`linear_model.lasso_path`) is more than + 200x times faster than before. + + - It is now possible to get probability estimates from a + :class:`linear_model.LogisticRegression` model. + + - module renaming: the glm module has been renamed to linear_model, + the gmm module has been included into the more general mixture + model and the sgd module has been included in linear_model. + + - Lots of bug fixes and documentation improvements. + + +People +------ + +People that made this release possible preceeded by number of commits: + + * 207 Olivier Grisel + + * 138 `Fabian Pedregosa <http://fseoane.net/blog/>`_ + + * 97 `Peter Prettenhofer <http://sites.google.com/site/peterprettenhofer/>`_ + + * 68 `Alexandre Gramfort + <http://www-sop.inria.fr/members/Alexandre.Gramfort/index.fr.html>`_ + + * 59 `Mathieu Blondel <http://www.mblondel.org/journal/>`_ + + * 55 `Gael Varoquaux <http://gael-varoquaux.info/blog/>`_ + + * 33 Vincent Dubourg + + * 21 `Ron Weiss <http://www.ee.columbia.edu/~ronw/>`_ + + * 9 Bertrand Thirion + + * 3 `Alexandre Passos <http://atpassos.posterous.com>`_ + + * 3 Anne-Laure Fouque + + * 2 Ronan Amicel + + .. _changes_0_5:
