The biggest change was moving the debug view of the Flow editor into the side panel, making it less confusing when debugging multiple flows. The Preview browser can now reuse previews (and therefore keeping the setup in the view), making flicking through images much more responsive. Apart from that, a bunch of bug fixes and little improvements.
The Preview browser now handles errors better that occur while generating previews.
File choosers with a filter text field now only show items that match the filter and the selected file format.
The Debug view in the Flow editor has been integrated into the side panel of the editor window rather than being display as separate frame (this also applies to all the flow execution listeners). This makes it easier to debug several flows in parallel, as the view changes based on what flow has been selected in the editor. It is still possible to detach the view and display it in a separate frame via the right-click popup menu on the tab title.
adams-moa: compiled a custom (unofficial) version of MOA to bundle with ADAMS to fix compatibility issue of jclasslocator library versions between MOA (0.0.12) and ADAMS (0.0.15).
adams-weka and adams-weka-lts:
The WekaSpreadSheetToPredictions transformer now handles spreadsheets with string labels in the actual/predicted columns, not just when containing numeric label indices.
The ConfusionMatrix output generators in the Classify tab of the Weka Investigator now maintain the order of the class labels from the dataset.
When deserializing a session, the data tables (eg in the Preprocessing tab) get resized using optimial column widths, instead of using a width of only a few pixels.
Setting/updating/removing column filters on the Data tab in the Weka Investigator now gets applied to the correct column.
The Weka Multi-Experimenter no longer generates a NullPointerException.
The generic search panel now allows toggling between regular expression search and simple sub-string search via its popup menu of the text field.
Containers now make use of the more intelligent plain text rendering available through the adams.data.textrenderer.TextRenderer class hierarchy. Speeds up debugging of large objects, like spreadsheets.
Added support for caching previews and reusing them in the Preview browser. However, reuse is currently only supported by image preview handlers.
The ObjectLocationsSpreadSheetReader report reader can add polygon coordinates to the report as well (as long as X and Y coordinates are present in two separate columns).
The ByMetaDataNumericValue object filter now allows using x/y/width/height as key as well.
The left-click processors in the ImageViewer can now specify what additional keys have to be pressed (shift/alt/ctrl/meta).
The following content handlers in the Preview browser now support an optional alternative location for meta-data: ObjectCentersFromReport, ObjectLocationsFromReport, ObjectLocationsFromSpreadSheet.
adams-ml: The ConfusionMatrix transformer now offers the classLabels option for enforcing the order of labels in the matrix.
adams-weka and adams-weka-lts:
The WekaSpreadSheetToPredictions transformer now allows sorting of labels with a specified comparator.
The SimpleArffLoader now supports the sparse ARFF format as well.
upgraded multisearch-weka-package to 2020.2.17
upgraded Weka to 3.9.4-fork-0.0.1
upgraded Weka to 3.9.0-fork-0.0.9
adams-spectral-2dim-core: The WekaFilter post-processor can now turn off wrapping in a SpectrumFilter (on by default).
Added the MergeGrid multi-image operation for combining images generated by the SubImages/Grid operation. Combines the annotations as well, but does not remove duplicate or overlapping objects.
Added new left-click processors for the ImageViewer: ViewObjects, DeleteObjects, AddMetaData.
Added report writer for object locations: ObjectLocationsSpreadSheetWriter
The object filter AttachOverlappingMetaData allows the copying of meta-data between overlapping objects, eg reference data. The meta-data is copied from a report in storage.
adams-weka and adams-weka-lts: The NominalToNumeric filter allows you to either use the interal representation of the labels as numeric values or you can extract the numeric part from the label via regular expression replacement.
