ADAMS (Posts about heatmap)

update 30/4

FracPete — Wed, 29 Apr 2015 20:43:55 GMT

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")

Quite a number of changes have made their way into ADAMS since the last post...

Libaries

MEKA upgraded to 1.7.5 (module: adams-meka)
WekaExcel upgraded to 1.0.5 (module: adams-weka) ExcelLoader always omitted last row in spreadsheets

Fixes

Weka Explorer plugins FixedClassifierErrorPlot, ThresholdCurve now free up memory when the dialog gets closed
SpreadSheetColumnRange/Index sometimes failed in conjunction with variables
WhileLoop control actor did not re-apply variables once the looping started, ie conditions couldn't use variables that got updated within the loop

Extensions

the adams-heatmap module received a fair number of changes:
- heatmaps no longer have the restriction of having a minimum of 0
- heatmap filters are now prefixed with "Heatmap" to avoid name clashes
- HeatmapInfo transformer for outputting some info about a heatmap
- added number of feature generators
- removed instance generators (and adams-weka dependency)
Weka filter "Scale" (unsupervised/instance) allows you to scale the values of a row eg to interval 0 to 1
any spreadsheet table should now allow you to not only display a histogram of a row/column, but also simply plot the row/column values
math/boolean expressions now offer additional functions: cbrt (cube root), sinh, cosh, tanh, atan, atan2, hypot, log10, signum
SimplePlot sink - a simplified version of the SequencePlotter sink

That's it for now. Have a nice weekend!

Time for a little round-up of what's happened to ADAMS lately...

Fixes

sluggish behavior of flow editor (opening/saving/undo) due to regression in EnumOption option handling class (finding/registering property editor on demand was very slow)
obtaining subsets from Notes objects only returned the first element of each type
TryCatch control actor properly flushes the tokens of its subflow when an error occurs
Upper/LowerCase conversions take locale into account
ImageProcessor tool works properly with the revamped ImageFileChooser dialog
PreviewBrowser tool displays arrays in a more sensible fashion
WekaFileReader didn't output an Instances object if no rows present

Addtions

print support got added to the PDF viewer (tool and sink)
ImageHistogram sink added to adams-imaging
additional actors for the adams-heatmap module * HeatmapArrayStatistic transformer * HeatmapLocateObjects transformer * HeatmapHistogram sink
Heatmap viewer can display a histogram of current heatmap
