# clj-ml History ## v0.1.0 - 2011-04-11 ### New Features * New filter wrappers added: `RemoveUseless` as `:remove-useless`, `Add` as `:add-attribute` * New classifier wrappers added: `PaceRegression`, `RandomForest`, M5P Trees and boosted stumps (`LogitBoost`), `AdditiveRegression`, Gradient Boosted Decision Trees, `RotationForest`, `SPegasos` * Increased the number of options that can be specified for classifiers. * Adds `:clj-streamable` and `:clj-batch` filters which allow for custom functions to be provided for filtering the dataset. * More idiomatic way and using/applying filters that allows threading. * Attribute names can now be specified in the filters and other accessor functions instead of requiring the columns index. * New utility functions: `into-fast-vec, dataset-replace-attribute, dataset-class-values, dataset-nominal?, make-apply-filters, classifer-copy-and-train, keyword-name, headers-only, dataset-class-name, attribute-labels-as-strings, dataset-name` * Speed improvement in `dataset-as-maps` ### Bug Fixes * `is-dataset?` reports falses correctly now. * A large ammount of type hinting was added to many areas where it was slowing down real use-cases. * Loading and saving instances functions now work with streams (not just files or file names). * `nil` values are allowed in datasets (represented as `NaN`s in weka) ## v0.0.4 - 2010-10-28 ### New Features * Upgraded to Clojure 1.2. (Ben Mabey) * Upgraded deps and swithced to modular Incanter dependencies. (Ben Mabey) ## v0.0.3 - 2010-02-28 * Initial release by Antonio Garrote.
