New Release - Hugin 7.2
November 25, 2009
Today we are releasing a new version of the HUGIN software (v7.2). The
main new features of this release are:
- A new Application Programming Interface (API) for PDAs. The HUGIN
Decision Engine now has an API that makes it possible to run
applications using HUGIN functionality on a PDA.
- HUGIN software has been extended with a new Monte Carlo algorithm to
find the most probable configurations of a set of nodes in a network.
- Parameter estimation from data for object-oriented networks using
the Expectation Maximization (EM) algorithm is now supported by the
HUGIN Graphical User Interface (GUI). The parameter estimation is
performed using the EM algorithm supporting missing values in data.
HUGIN Graphical User Interface v7.2
The HUGIN Graphical User Interface has been improved with various new
features. This includes:
Finally, efforts have been put into improving the performance of the
HUGIN Graphical User Interface.
HUGIN Decision Engine v7.2
The HUGIN Decision Engine has been extended with the following
features:
- An algorithm for finding the "requisite" parents of a decision node
in a LIMID has been implemented.
- A Monte Carlo algorithm for finding the most probable configurations
of a set of nodes has been implemented.
- A new triangulation method has been implemented: This method
triangulates each prime component using all of the elimination based
triangulation heuristics and uses the best result.
This triangulation method is now used by the compilation operation
when compiling untriangulated domains.
- As the elimination based triangulation heuristics may produce
non-minimal triangulations, an extra pass that removes "redundant
fill-in edges" has been added to these heuristics.
