v0.1.3 - 2011-10-07

New Features

• added new attribute selection namespace

v0.1.2 - 2011-06-14

New Features

• added dataset-weights function

Bug Fixes

• Does not create new ClojureInstances with dataset-seq, just uses weka's built in enumerator.

v0.1.1 - 2011-06-14

New Features

• added FastRandomForests which are more space and time efficient that Weka's default implementation.

Bug Fixes

• More typehinting for filter creation.

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 NaNs in weka)
