Initially, I had a release planned for this week, but with a plethora of minor bug fixes/UI improvements happening and other projects demanding time, I had to abandon this plan. Hopefully, this will eventuate next week instead.
Interactive actors now call the root actor's stopExecution method instead of their own, in order to stop the flow.
The SelectArraySubset interactive transformer now updates the message label with each interaction and double-clicking on an item automatically selects it and accepts the dialog.
Spreadsheet tables now interpret Long cell values as Double, in order to get correct sorting of columns with mixed Long/Double values.
adams-weka: Fixed the batch-filtering functionality of the Weka Investigator's preprocess tab.
The ImageViewer sink now accepts objects implementing BufferedImageSupporter as well.
adams-spectral-core has been renamed to adams-spectral-2dim (as it is for 2-dimensional spectra).
Start buttons now display a tooltip if disabled, explaining why process cannot be started (hover over the button to display it).
PCA tab now offers checkbox for skipping nominal attributes.
Closing a tab now prompts the user whether to go ahead with it (to avoid losses of tabs when quickly switching between them and accidentally hitting the close button).
The ClassifierErrors output generator now allows anti-aliasing to be configured (default is Auto, i.e., if more than 1000 datapoints, it gets turned off to speed up the plot).
The unsupervised instance-based filters DatasetCleaner and DatasetLabeler now have the additional flag -only-first-batch, which applies the filter only to the first batch of the data.
Added RomanToInt and IntToRoman conversions for handling Roman numerals.
Added Kendall-Theil robust regression calculation: ArrayKendallTheil, StatUtils.kendallTheil, KendallTheilOverlayPaintlet.
Added the BufferedImageSupporterToBufferedImageContainer conversion to allow attaching of metadata.
Added meta-data text overlay for images, e.g., used in the ImageViewer sink: MetaDataText.
The SetContainerValue control actor allows updating of a single container value, using data from either a callable actor or storage.
The PredictionEccentricity transformer allows the calculation of the eccentricity for the predictions generated by a regressor.
The ActualVsPredictedPlot sink now implements AntiAliasingSupporter, i.e., you can turn on/off anti-aliasing for pretty/fast plots.
Added PLS spectrum batch filter, which makes use of the new PLS algorithm class hierarchy to transform the spectral data.
Added PCA spectrum batch filter.
The JFreeChartPlot sink allows plots from spreadsheet columns using JFreeChart plot library and the JFreeChartFileWriter outputs image files from generated plots.
The Spreadsheet file viewer now has a chart plugin using JFreeChart.
Added WekaGenericPLSMatrixAccess transformer which gives access to internal PLS matrices of the new AbstractPLS class hierarchy.
PLS-based classifier that uses the new PLS class hierarchy: weka.classifiers.functions.PLSWeighted.
The classify/cluster tab in the Weka Investigator now have Build model evaluations that just generate a model and save it to disk.
The Data table of the Weka Investigator now has a plugin for plotting using JFreeChart.
The WekaSpreadSheetToPredictions transformer allows the recreation of an Evaluation object simply from predictions of a model (actual/predicted).
weka.filters.FilteredFilter is a filter for applying a pre-filter to the data before using the main filter (eg for selecting a subset).
The Weka Investigator now offers an output generator for displaying/calculating the Prediction Eccentricity of the predictions (Classify tab, numeric classes only).
It is now possible to compare the predictions of two models evaluated in the same way on the same dataset (with a numeric class) through the Compare models menu item in the result history of the Classify tab of the Weka Investigator.
