The main improvement of the HUGIN software in version 9.0 is a new Look & Feel experience of the HUGIN Graphical User Interface and associated updates. In addition, users may experience a smoother installation experience on the Windows and macOS operating systems.
HUGIN Graphical User Interface v9.0¶
The HUGIN Graphical User Interface has been improved with various new features. These include:
- New Look & Feel implemented across all supported platforms (Linux, macOS, and Windows)
Drag & Drop to open a file
Improved PDF export
The layout of the menus and the toolbar has been refactored
Dark and white themes are now available for the GUI. Themes can be swapped in the preferences menu.
Node edges are significantly more smooth
New modern icons that are bigger and transparent to support the new themes and larger resolutions
- Improvements to the Data Frame functionality
Menu item to create a new empty DataFrame
Double-click on a row also takes values of function nodes in the corresponding case into consideration
New Moment Statistics Dialog
New Statistical Measures of Error Dialog
The implementation of the batch propagation functionality of the Data Frame has been improved. This includes the addition of a set of new measures that can be computed after the propagation of a case, e.g., variance and standard deviation of a numeric node.
Store size of instance nodes and relative positions of interface nodes
Feature Selection Analyzer now supports continuous nodes as target
Tables are not created for chance nodes when leaving the Structure Learning Wizard
macOS: The Hugin GUI application is now provided in two separate packages — with native support for M1 and Intel Macs, respectively.
Other minor improvements
Finally, work has been done to improve the performance of the HUGIN Graphical User Interface.
HUGIN Decision Engine v9.0¶
The HUGIN Decision Engine has been extended with the following features:
CSV representations of data sets can now be generated as text strings. These strings can be parsed by the usual functions for parsing DataSet specifications.
A new “variance” operator is available for use in expressions in models for function nodes
The Hugin Web Service API now supports OpenJDK
The HDE for macOS is now universal — with native support for the ARM64 and x86_64 architectures.
