• Bug fixes and Other small improvements

Changes from Build 6909 to Build 7000:

• Views added to list of tables in database connections
• Bug fixes
• Other small improvements
• Included functionality from the official release 6.9

Changes from Build 6906 to Build 6909:

• Bug fixes
• Other small improvements

Changes from Build 6904 to Build 6906:

• The analysis is now only performed for nodes in the sensitivity set. This has corrected some rounding errors
• Other small improvements

Changes from Build 6800 to Build 6904:

• Color map included in the CPT shown in the parameter sensitivity analysis dialog
• Preliminary version of a sensitivity set graph dialog included
• Multiple adjustments and improvements to the parameter sensitivity dialog have been made
• Corrected an error in the API implementation of parameter sensitivity analysis

HUGIN BIOTRACER

• テーブル・ジェネレータでの分布にLogNormal、PERT、三角分布を追加
• 連続変数の自動離散化をサポート
• IntervalDCNodesのモニター・ウィンドウに密度表示モード
• パラメータ感度分析

Change log for Hugin BIOTRACER

• VOI analysis now supports CG nodes as indicators
• What-if Analysis with continuous evidence (compute posterior beliefs with mu + minus some number of standard deviations )
• Analysis Wizard: enabled "Accuracy" pane in CG networks
• Fixed: bug related to the use of case counts in data files
• Status Bar now displays the size of the policy for a selected decision node
• Status Bar now displays the size of the utility function associated with a selected utility node
• Flip network layout upside down: Network->Flip network
• Introducing OOBN EM: EM Learning wizard now enabled for OOBNs as well (feature is working, but still under development).

• Corrected bug in the States Generator Panel. A Class Cast exception was throws while launching the States generator panel for a node that has two parents and at least one of them is a Discrete Decision Node.
• corrected bug! Log files where locked by windows even after the corresponding project frame was closed in the gui.
• Bug in the DataAcquisition panel in the Learning Wizard when trying to open a file with invalid format. Corrected!
• Bug correction! Closing all frames by selecting in the menu "Windows --> Close All" would throw a null pointer exception.
• Data preprocessing panel (Learning wizard, Em wizard, etc) : The user can now choose between UTF-8 and iso-8859-1 encoding when opening a .dat file.
• Corrected a Null Pointer Exception bug that occured occationally in the Node States Generator Panel.
• Conflict analysis - reporting resolution hypothesis and partial conflict to usage log
• Corrected bug in the States Generator Panel. A Class Cast exception was throws while launching the States generator panel for a node that has two parents and at least one of them is a Discrete Decision Node.

• Parameter Sensitivity Analysis with two inputs from one CPT.
• Parameter Sensitivity Analysis with two inputs from two different CPTs.
• Computing Sensitivity on multiple cases from a case file in Parameter Sensitivity Wizard.
• Support for computing the k-most probable configurations has been included in the Joint Analysis Dialog using a Monte Carlo based algorithm.

• Learning Wizard: Discretization using Information Entropy Minimization (U. M. Fayyad and K. B. Irani. 'Multi-Interval discretization of continuous valued attributes')
• Allowing the creation and parsing of invalid Expressions in the Expression Builder Wizard.
• Computing Senssitivity on multiple cases from a case file in Parameter Sensitivity Wizard.

Changes from Build 7001 to Build 7002:

• Min - Max Sensitivity value color maps in Parameter Sensitivity Analysis.
• Support for selecting a sensitivity line to display in the graph when performing Parameter Sensitivity analysis for all states.
• The hypothesis variable combo box is rendered to visually show nodes with evidence (Parameter Sensitivity Wizard).
• Displaying the upper and lower bounds of the sensitivity lines (Parameter Sensitivity Wizard).
• Allowing the Parameter Sensitivity Analysis for influence diagrams with instantiated decision nodes.
• A new Tab in the Parameter Sensitivity Wizard (Constraints) for supporting user specified constraints. Supports a one event constraint, a two event difference constraint and a two event ratio constraint and allows the user to manually implement the changes or automatically adopt them. It supports the specification of one or two constraints.
• When inserting parent nodes in an expression their types (Boolean, Labelled etc.) are displayed (Expression Builder Wizard).
• Fixed bug inserting parents in an expression when building a Distribution or a NoisyOr expression (Expression Builder Wizard).
• Parsing an expression written in edit mode when returning to build mode so the tool can use its arguments in the argument fields (Expression Builder Wizard).
• Added help pages to Expression Builder and Parameter Sensitivity Wizards.

Changes from Build 7000 to Build 7001:

Build date: 24 January 2008

• Correlation analysis dialog
• Joint Dialog with relaxed requirement on network to allow analysis when all decisions are instantiated
• Color map in parameter sensitivity analysis display parameter sensitivities instead of parameter values.
• When opening a file with unknown extension, the file may optionally be probed for a net,oobn or hkb description

Changes from Build 6906 to Build 7000:

• Parameter sensitivity analysis added
• Monitor windows now display mean and variance for numerical nodes
• Included functionality from the official release 6.9

Changes from Build 6905 to Build 6906:

• Expression builder now supports bar mode and pure bar mode display of table content
• Bug related to displaying the "table" of a decision node fixed
• Bug related to reordering parents of utility nodes fixed
• "show as table" always enabled

Changes from Build 6904 to Build 6905:

• The analysis wizard will display state labels or state values depending on the node settings
• Other small improvements

Changes from Build 6803 to Build 6904:

• "truncate" operator for distributions taking the form truncate ([lower value], <Distribution>, [upper value]). An example is "truncate (-4, Normal (0,1), 4)" which truncates the normal distribution at -4 and 4, respectively. Either the lower or upper value may be left unspecified
• Improved discretization dialogs (both edit and run mode)
• Bitmap view of a CPT. A white pixel is a zero value.
• Preliminary version of a revised Table Generator implementation. The revised Table Generator eases the specification of expressions and is more intuitive

Changes from Build 6802 to Build 6803:

• Calculation of mean and variance of numerical nodes when selected
• Belief bar resizing in Node List
• Equi distant discretization in run mode
• Show mean calculation in User Log
• It is now possible to have a mixture of type in "if"-expression, e.g., it is possible to specify the following expression
  "if (X>0, Normal (160,100), 0)"
• It is possible to discretize an interval node with evidence where the evidence has been entered as a value (as opposed to selecting a state)

Changes from Build 6800 to Build 6802:

• Restore original discretization
