This page describes enhancements delivered by RapidMiner Server 2.4.
Model management
RapidMiner Server 2.4 provides template processes and a template app for implementing model management within applications that employ predictive modeling. You can now design model performance monitoring and resulting corrective actions into your processes.
Enhancements and bug fixes
The following improvements are part of RapidMiner Server 2.4.
Enhancements
- Added an HTML5 map type that can display locations specified by latitude/longitude
- RapidMiner Server connections are now editable in RapidMiner Studio
- Additional JDBC drivers can be added to the running Server by adding a "jdbc_properties.xml" file in the SERVER/standalone/configuration/.RapidMiner folder. The file structure is identical to the same file created by Studio in the HOME/.RapidMiner folder. Copy and paste the file to RapidMiner Server and press the Reload database drivers link in the Database connections administration view.
- Processes executed by apps (app initialization process or via interaction effects) can now change app variable values
- Macros defined in the process context with the same name as an app variable now write the macro value back to the variable. To enable this feature for an existing app, select the Allow processes to set app variables checkbox in the app's general settings.
- New option to display data labels for HTML5 series and pie charts
- New option to specify tick interval for x/y axis for most HTML5 charts, reducing overcrowding
- New option to customize the empty data message for HTML5 charts
- New option to disable icons for trees in visualization components
- New option to expand all nodes from the start for trees in visualization components
- Improved warning error message style in many locations
- Updated HTML5 chart libraries (for example, auto rotation of axis labels)
- Improved Mac installation experience by fixing keyboard shortcuts
Bug fixes
- BUGFIX: Fixed rare problem that prevented app loading
- BUGFIX: HTML5 scatter charts now correctly use numerical color gradients respecting the selected color scheme
- BUGFIX: HTML5 series charts no longer add the category attribute to the list of series for numerical categories
- BUGFIX: App initialization processes now have access to all App variable values via context macros (access via '%{variable_name}')
