About: A thin Python wrapper that uses the javabridge Python library to communicate with a Java Virtual Machine executing Weka API calls.

Changes:
  • added method "ndarray_to_instances" to "weka.converters" module for converting Numpy 2-dimensional array into "Instances" object
  • added method "plot_learning_curve" to "weka.plot.classifiers" module for creating learning curves for multiple classifiers for a specific metric
  • added plotting of experiments with "plot_experiment" methid in "weka.plot.experiments" module
  • "Instance.create_instance" method now takes list of tuples (index, internal float value) when generating sparse instances
  • added "weka.core.database" module for loading data from a database
  • added "make_copy" class method to "Clusterer" class
  • added "make_copy" class method to "Associator" class
  • added "make_copy" class method to "Filter" class
  • added "make_copy" class method to "DataGenerator" class
  • most classes (like Classifier and Filter) now have a default classname value in the constructor
  • added "TextDirectoryLoader" class to "weka.core.converters"
  • moved all methods from "weka.core.utils" to "weka.core.classes"
  • fixed "Attribute.index_of" method for determining label index
  • fixed "Attribute.add_string_value" method (used incorrect JNI parameter)
  • "create_instance" and "create_sparse_instance" methods of class "Instance" now ensure that list values are float
  • added "to_help" method to "OptionHandler" class which outputs a help string generated from the base class's "globalInfo" and "listOptions" methods
  • fixed "test_model" method of "Evaluation" class when supplying a "PredictionOutput" object (previously generated "No dataset structure provided!" exception)
  • added "batch_finished" method to "Filter" class for incremental filtering
  • added "line_plot" method to "weka.plot.dataset" module for plotting dataset using internal format (one line plot per instance)
  • added "is_serializable" property to "JavaObject" class
  • added "has_class" convenience property to "Instance" class
  • added "repr" method to "JavaObject" classes (simply calls "toString()" method)
  • added "Stemmer" class in module "weka.core.stemmers"
  • added "Stopwords" class in module "weka.core.stopwords"
  • added "Tokenizer" class in module "weka.core.tokenizers"
  • added "StringToWordVector" filter class in module "weka.filters"
  • added simple workflow engine (see documentation on Flow)

Logo ADAMS 0.4.8

About: The Advanced Data mining And Machine learning System (ADAMS) is a novel, flexible workflow engine aimed at quickly building and maintaining real-world, complex knowledge workflows.

Changes:
  • 13 new actors
  • 1 new conversion
  • new module adams-access: for accessing MS Access databases (read/write)
  • adams-heatmap module overhaul
  • adams-imaging: barcode (QRCode etc) encoding/decoding, multi-image operations (and, or, xor)
  • Flow editor gets a "quick edit" tab
  • MEKA upgraded to 1.7.5
  • Weka filter "Scale" (unsupervised/instance) allows you to scale the values of a row eg to interval 0 to 1
  • SimplePlot sink is a "dumbed down" version of the SequencePlotter with only basic options -- enough to create good looking plots quickly
  • Upper/LowerCase conversion take the locale into account now
  • added print support for PDFs
  • fixed sluggish behavior in Flow editor (open/save/undo)
  • TryCatch correctly flushes token now
  • spreadsheet column range/index sometimes failed in conjunction with variables
  • fixed memory leak in Weka Explorer plugins FixedClassifierErrorPlot, ThresholdCurve
  • WekaExcel upgraded to 1.0.5 (no longer omits last row in sheets)
  • WhileLoop did not react to changes in variables once looping, ie conditions couldn't make use of variables
  • ImageProcessor now works again with the improved ImageFileChooser dialog
  • PreviewBrowser displays arrays in a more meaningful way
  • WekaFileReader didn't output empty datasets in DATASET mode
  • obtaining subsets from Notes objects only resulted in first element being retrieved
