WinMine Toolkit

Established: October 5, 2002

    The WinMine Toolkit is periodically updated as we make improvements and fixes. You can periodically visit the update page to see if you should download a fresh version of the tools. You can also provide us with your email either when you download the tools or by sending us mail, and we will include you on the mailing list.

    Following is a list of updates that have been made to the toolkit since it was released.

    DateUpdate
    5/18/01Bug Fix: DataConverter.exe was adding an extra space on the first row of a space-separated data file.
    5/21/01Bug Fix: Dnet.exe was not accepting input while in interactive (“-gui”) mode. DataSplit.exe had “.dst” as the default data file extension.
    5/22/01Bug Fix: DnetLogscore.exe was crashing if the name of the input model file did not have an extension.
    5/29/01Bug Fix: Command-line executables were not displaying the default values.
    6/08/01Bug Fix: DataConverter.exe: Column headers not read in correctly for SQL data, and variable name edits not persisting.
    8/09/01Bug Fix: DataSplit.exe: Case IDs not persisted to output files
    9/28/01Bug Fix: Dnet.exe was failing with marginal-input distributions in a Bayesian network.
    10/04/01Bug Fix: Build from previous fix resulted in buggy watermarks in DataConverter.exe.
    10/30/01Performance: DataConverter.exe works faster for large datasets
    1/15/02Bug Fixes: DataConverter.exe was failing for empty columns and was not giving good error messages

  • Version 2.0 of WinMine now available!

    The major functional changes to the tools are as follows:

    1. Complete tables can now be used for the local distributions. For now, if you use any complete-table distribution, *all* distributions must be complete tables. Only complete data can be used when the local distributions are complete tables.2. You can now specify both partial-order constraints and forbidden-edges constraints. These are specified in the plan file.3. For Bayes nets with complete tables, you can view the compelled and reversable edges using DnetBrowser.exe.4. Some advanced import options have been added to DataConverter.exe

    Some bug fixes:

    1. DnetLogscore.exe was not correctly computing the posterior for a node when (a) Markov-blanket inference was being used and (b) the target node was missing in the data.2. The code for guessing model-as-binary was not implementing the algorithm described in the tutorial

    Some subtle changes that could cause problems when using scripts:

    1. The ‘-acyclic’ flag in DnetLogscore.exe has changed to ‘-mblanket’ to avoid confusion with the ‘-acyclic’ flag used by Dnet.exe2. The default number of split points to try for continuous variables has changed from one to seven.

    • 2/10/06Version 2.5. The GES algorithm was (finally) added to the toolkit. Run GES with the separate GES.exe command-line tool.
