update 30/4

It's time for a round-up of all the changes that have happened...

Fixes

  • the ORDER BY clause of the SpreadSheetQuery transformer got applied to the input spreadsheet rather than final one, screwing up the WHERE clause
  • the abstract class AbstractProcessWekaInstanceWithModel did not clear the internal model when its options got changed; affected transformers: MekaClassifying, Weka/MOAClassifying/Clustering

Modifications

  • SpreadSheetTable now uses plugin architecture for processing/plotting cols/rows/cells in its popup menus
  • Min/Max heatmap feature generators can output the position now as well
  • spreadsheet plot generators can generate plot name now also based on range of cell values
  • Excel and ODF spreadsheet readers now support "no" or "custom" headers
  • ForLoop source can output integers now as array as well
  • the message of the Stop control actor can contain variables now as well

Additions

  • added NewHeatmap source to adams-heatmap
  • added HeatmapGetValue/HeatmapSetValue transformers to adams-heatmap
  • added VotedImbalance meta-classifier to adams-weka classifier generates X number of resampled datasets from input data, limiting size to smallest class, building base-classifier on them and then uses Vote meta-classifier for making predictions
  • added PromptUser boolean flow condition, asking user whether to execute conditional actor or not
  • added "Append datasets" and "Merge datasets" to the main menu of the adams-weka modulel; uses wizards to guide the user for combining datasets
  • added specialized pages to the wizard: SelectFilePage, SelectMultipleFilesPage, WekaSelectDatasetPage, WekaSelectMultipleDatasetsPage
  • added new (optional) Look'n'Feel: PgsLookAndFeel, which can be activated in the GUIHelper.props file
  • new source for outputting integers: IntegerRange uses a range string and a maximum to generate these integers (eg "3-5,7,12,18-last")
