March 21, 2018: New Release – HUGIN 8.6
Today we are releasing a new version of the HUGIN software (v8.6).
The main new features of this release are HUGIN Decision Engine Application Programming Interfaces for Android and iOS platforms.
HUGIN Graphical User Interface v. 8.6
The HUGIN Graphical User Interface has been improved with new features:
– The HUGIN Graphical User Interface now has a Derby SQL database interface for loading data cases into a Data Frame.
– Other minor improvements.
Finally, work has been done to improve the performance of the HUGIN Graphical User Interface.
HUGIN Decision Engine v. 8.6
The HUGIN Decision Engine has been extended with the following features:
– A new HUGIN Decision Engine Application Programming Interface for the Swift programming language including support for the Apple iOS platform.
– A new HUGIN Decision Engine Application Programming Interface for the Android platform.
– Support for creation of temporal clones of Continuous Gaussian (CG) nodes in Dynamic Bayesian Networks (DBNs). This can, for instance, be used to create a Kalman Filter model as well as other models with a mixture of discrete and continuous nodes. Both exact inference and partial Boyen-Koller approximation are available for models with temporal clones of CG nodes.
Tools introduced with HUGIN v. 8.6
This release introduces a new tool to integrate Bayesian Belief Networks (BBNs) and geographic information system (GIS).
HUGIN QGIS BBN plugin
The QGIS Processing script makes it possible to apply a Bayesian network to each point in one or more raster layers and output a new raster layer with the results. For each point potentially covering multiple layers, the Bayesian network inserts and propagates the values of the nodes linked to raster layers. The user can select a number of output values: index of state with maximum probability, probability of state with maximum probability, and maximum expected utility.
