What's New in RapidMiner Server 7.6.0?
Released: August 15th, 2017
The following describes the enhancements and bug fixes in RapidMiner Server 7.6.0:
New features
- It is now possible to set access rights in RapidMiner Server not only for the current folder, but also for all of its nested subfolders. Go to Permissions in the web UI and select Set recursively for subdirectories to access this feature. Note that the checkbox only appears after changes to the permissions have been made!
Enhancements
- Improved performance of web services, especially under heavy load. Make sure to read our Performance Tuning for RapidMiner Server documentation for heavy duty usage!
- Improved logging of the installer in case an invalid license is entered both during GUI and headless installations.
- Sending notification emails can now be configured in the system settings to make use of all modern connection security and authentication mechanisms like TLS 1.2 + PFS
- The sender of notification emails can now be configured in the system settings
- Licenses are now valid for the full last day until midnight
- Improved handling of infeasible parameter values for Self-Organizing Map
- Changed default sampling type parameter for Validation operators to automatic
- Write Message now has a parameter option to append to existing files instead of overwriting them
- Logistic Regression and Generalized Linear Model learners now have a threshold output where they deliver a threshold value optimized for maximal F-measure
- Improved handling of missing and infinite values for Normalize
- Improved handling of missing or broken compatibility numbers in the process xml
- Made behavior of add as label parameter consistent for all cluster operators
- Improved checks for empty example sets in cluster operators
- Improved shown capabilities for cluster operators and added quick fixes for inconsistent parameter selection
- Reduced some internal logging by moving it behind the debug flag which can be activated in the preferences
- Updated Java for Windows and Mac OS X to version 8u141
Bugfixes
- Fixed reproducibility of results when concurrent operators (e.g. Loops) are involved.
- Fixed behavior of Loop Parameter inside parallel loops.
- Generate Weights (LPR) and Local Polynomial Regression now provide additional kernel parameters for the numerical measure KernelEuclideanDistance instead of failing
- Fixed Gradient Boosted Trees renderer, it no longer shows wrong edge labels and incorrect value sets
- Logistic Regression, Generalized Linear Model, Gradient Boosted Trees and Deep Learning operators no longer crash the software if certain temporary folder permissions are missing
- Logistic Regression and Generalized Linear Model learners now use 0.5 as the threshold as other binominal learners
- Fixed behavior of Loop Attributes when only one attribute is selected for parallel execution
- Fixed Average for Performance inputs that contain AUC
- Fixed side-effects of Apply Threshold in other branches of the process
- Fixed rare crash in Create Association Rules under certain parameter configurations
