These release notes accompany the Insightful Miner 3.0.1 update. This document describes the changes between the initial 3.0 release and 3.0.1. For general information regarding Insightful Miner 3.0, see the ReleaseNotes.htm file in the Insightful Miner distribution.
When the initial Insightful Miner 3.0 release is installed on Windows, the product is registered as Insightful Miner 3.0 Release 1. Due to the conventions of the Microsoft Windows Installer technology, this is the product name used in the Windows Start menu and in the installation maintenance dialogs. Installing the 3.0.1 patch does not change the product name to Insightful Miner 3.0.1 in all locations. See the About box available through the Help menu to check that the 3.0.1 version is installed.
The purpose of this release is primarily to fix defects found since the 3.0 release. The improvements between 3.0 and 3.0.1 are:
Avoid duplicate error messages in Aggregate node when expected column not found.
Prevent inconsistent results in Classification Agreement after a Predict node due to stale model information.
Remove selection before deleting items from column lists to avoid ArrayIndexOutOfBounds
exceptions in dialogs.
Recognize user-specified columns in Classification Agreement.
Prevent links to Annotation nodes.
Prevent the context menu for the Explorer pane from extending off the screen.
Generate C code successfully for all model types on Solaris.
Handle additional forms of exponential notation (1e10, 1E10,
1E+10) when converting strings to doubles.
Table viewer now displays very large and very small numbers using scientific notation.
Minor improvements to file and database import/export.
Restore multiple-input links correctly on worksheets with a large number of links.
In the S-PLUS Script dialog, avoid adding extra line return characters on Windows and dropping newlines on UNIX due to incorrect end-of-line modifications when using the Edit button.
When merging two columns, check for identical levels when merging metadata to avoid having two copies of the levels in the list of levels.
In the Missing Values dialog, include an empty string "" in the Key Column option link so the user can set the key to be empty if it was accidentally set to some other value.
Refresh network layout information when the Neural Network viewer is launched during run to make sure the layout matches the current settings.
Convert separators in file paths to the appropriate separator for the platform in Export HTML, Export PMML, and Generate C Input.
Improve the stability of the license manager interaction on Solaris.
Avoid hard crashes during exit when a license is not available.
Present license management warning and error messages in the console
where IMiner was started rather than in dialogs.
Improve the formatting of some license manager administration messages on Solaris.
On Solaris, Insightful Miner may fail to start if the S-PLUS Library
for Insightful Miner is installed but S-PLUS cannot contact the
S-PLUS license manager or an S-PLUS license is not available. The
symptom is that the splash screen appears, and then the application
hangs or terminates. A workaround is to use a new command line
argument. IMiner -nosplus
opens Insightful Miner without attempting to access S-PLUS.
The following are corrections and clarifications for the Insightful Miner 3 Getting Started Guide.
Pg. 76, Step 41: Open the properties dialog of the Predict: Classification Tree node. The completed dialog page is shown in Figure 3.20.
Correction: Figure 3.20 is a Classification Tree node. It should be a Predict: Classification Tree node.
Pg. 82, Step 2: Drag and drop the Histogram component from the S-PLUS Library’s Explore:Two Column – Continuous folder ...
Correction: This should refer to the Explore:One Column – Continuous folder.
Pg. 90, Step 23: Open the scoring worksheet, examples/MortgageDefaultExample/MortgageDefault.Scoring.imw ...
Correction: This should be MortgageDefault.Score.imw.
Pg. 90, Figure 3.29 caption: Completed worksheet (MortgageDefault.scoring.splus.imw) ...
Correction: This should be MortgageDefault.Score-SPlus.imw.
Pg. 7, in Edit Button section: A mechanism for specifying which editor to use will be added for the final release.
Clarification: If you go to Tools:Options, you can select the desired editor in the Text Editor field.
Pg. 62, Step 43: Link the Partition node to the Write Text File nodes.
Clarification: This should say, “to the upper Write Text File node.”
Pg. 62, Step 48: ... type Mymortdef.test.txt.
Clarification: The file being created is a new file. If it exists, it is overwritten.
In version 3.0, the S-PLUS code for GAM prediction in the mortgage
default example creates an incorrect PREDICT.prob
column. The column contains two values rather than a full set of
values. The incorrect code is:
out <- IM$in1out$PREDICT.prob <- 1-pred.probout$PREDICT.class <- pred.class
The correct code is:
out <- data.frame(IM$in1, PREDICT.prob=1-pred.prob, PREDICT.class=pred.class)
The S-PLUS nodes in the following worksheets have been modifed to use the corrected code: MortgageDefault.complete.imw, MortgageDefault.Model-SPlus.imw, and MortgageDefault.Score-SPlus.imw. The code in MortageDefault.gamPredict.ssc has also been corrected.
Note that anytime the Open dialog is displayed, there is an Examples folder in the lower left corner of the dialog (upper right for Solaris). If you click this icon, it copies all the files from the installation examples directory to a users/username/examples directory (or users/username/iminer_work/examples directory for Solaris). Updated versions of files mentioned in the previous paragraph are present in the Insightful Miner 3.0.1 installation examples directory. If these files have previously been copied to another location, the revised versions will also need to be copied to obtain the latest version. After copying the files, change the copies to make them write-enabled.
Various properties that were global properties in Insightful Miner 2 are worksheet properties in Insightful Miner 3. References to the Global Properties help file have been changed to refer to the Worksheet Properties help file for the following help files: Bin, Modify Columns, Advanced Properties, Read Fixed Format Text File, Write Fixed Format Text File, and Expression Language.
