Improvements and Fixes in Recent Build

Version 6.07

New Features

(NeuroSolutions for Excel)

The Express Builder now automatically loads in the best-performing network, making it easier to perform an additional test or sensitivity analysis.
A training status dialog is shown during Leave-N-Out training, allowing one to pause or stop the training in the middle.
New option within Sensitivity about the Mean test, which allows the input variations to be within the min and max of each input column instead of +/- a number of standard deviations from the mean. This option is especially useful for binary inputs or inputs which have a non-Gaussian distribution.

(NeuroSolutions)

Fixed a bug with Conjugate Gradient learning would sometime spike to a high error and not recover.
Fixed a bug with the user interface would be very sluggish when working with a fairly large network configured with Levenburg-Marquardt learning.

(NeuroSolutions for Excel)

Fixed a bug with the Express Builder that would fail if 0% was chosen for either the cross validation or the testing set.
Fixed occasional crashes specific to Excel 2010.

Version 6.06

New Features

(NeuroSolutions)

The welcome screen of NeuroSolutions now has a "Recent News" section, which will inform users of any NeuroSolutions-related news, such as software patches, training courses or new product offerings.

(NeuroSolutions)

Fixed a bug where unsaved breadboards have their pattern and weights files stored in a temporary directory. This directory is now cleared out when the program starts in order to save disk space and to prevent old files being used with new breadboards.
Fixed a bug where if the number of network weights of a breadboard changes, the "Saved Error" of the Criterion is automatically set to a high value on the next training run to force a new best weights file to be saved with the proper number of weights.

Version 6.05

New Features

(NeuroSolutions)

Fixed a bug where a subset of NVIDIA graphics cards were causing NeuroSolutions to crash. The add-on has been disabled within the evaluation version. If you would like to evaluate the NeuroSolutions CUDA Add-on please contact us.
Fixed a bug with Greedy Search and Back Elimination procedures not functioning under certain conditions.

(NeuroSolutions Source Code)

Generated Source Code has been updated to support Visual Studio 2008

Bug Fixes

(NeuroSolutions)

Breadboards configured with either Quickprop or DeltaBarDelta were sometimes not able to open

(NeuroSolutions for Excel)

Vary a parameter: Fixed bug which saved the weights file from the last run instead of the best run when the parameter change caused the number of weights to change
Sensitivity About the Mean: Changed so it doesn't divide by the input standard deviation to get the sensitivity. Dividing by the input standard deviation was not correct as the variation of each input was already equivalent since it is varied by its standard deviation so what should be compared is just the variation of the output.

(Custom Solution Wizard)

Updated all of the Excel Project Shells so they work with a single input row

Enhancements

(NeuroSolutions)

Support added for Windows Vista
Code Generation and DLL support added for VC++ 2005

(Custom Solution Wizard)

VB Project Shells update: The VB Project Shells use DAO to read in the data files. DAO can only be used to read in data files with 255 or less columns. Some error checking was added to capture the case when the user's data file is too big and let the user know. The file "VBShell.vb" was updated.

VC++ Project Shells update: The buffer size in the function "FillArrayFromFile" of VC++ Project shells (in the file VCPPShell.cpp) was not big enough to read in large data files (large number of inputs). The buffer size was increased from 255 to 20,000.

Enhancements

(NeuroSolutions)

When the number of network weights change between runs, the Saved Error of the Criterion is reset to a high value so that the best weights will automatically get re-saved (if the Save Best switch is set).

(NeuroSolutions for Excel)

Test function now saves the original state of parameters it changes in the NeuroSolutions BB and restores then when it is done.
Added support for Excel 2007 (beta 2)

Fix: Crashed when trying to copy and paste a subclass of BackArbitrarySynapse
Fix: Warning message regarding backsynapse weights not matching when trying to test a breadboard with LM learning.
Fix: Resetting network would occasionally crash the program.

(NeuroSolutions for Excel)

The following problems were fixed for single output 2 class classification problems (when running Test or LeaveNOut):

Fix: The confusion matrix was not being created properly when the first desired row was the larger numeric value of the 2 classes (i.e. if the first desired value was a 1 when the classes were 0 and 1).
Fix: The confusion matrix data was not being put in the correct place when the 2 classes were other than 0 and 1.
Fix: The Performance measures were not getting separated by class and they were not being calculated correctly.

Enhancements

Addition of a Welcome menu and cosmetic enhancements to the NeuroSolutions demos.

Bug Fixes

(NeuroSolutions)

Fix: Single step exemplar did not function properly when cross validation was active
Fix: When generating source code for unsupervised nets with the learning turned off at the control, the network would still learn.
Fix: Hybrid networks configured with LM learning did not update the weights until after the network was paused
Fix: Source Code License: NSLearn.cpp failed to compile under g++ (GCC) 3.3.5 due to multiple uses of for variables outside the for statement context. This code was changed to be compliant with the ISO standard.

(NeuroSolutions for Excel)

Fix: After training the first time, the user could go to the desired file and set it to normalize across whatever datasets they choose. The problem was that when there was a Production set in NS for Excel the user’s change of the normalization setting was getting lost.

Leave N Out - Trains the network multiple times, each time omitting a different subset of the data and using that subset for testing. The outputs from each tested subset are combined into one testing report and the model is trained one additional time using all of the data.
Encode Two Class Column - The selected column of data is checked to verify that there are two classes contained within the column and is then encoded into another column. The data to be encoded can be textual or numeric, but must be translated to only numeric, integer codes. The encoded column will be written in the first empty column in the dataset.
Classification Report when testing on a single 2-class column - A classification report generated if the desired output of the testing set is a single two-class column.
Shift - The input data is adjusted to either move the inputs back by a specified shift value to do predictions or move the inputs forward to lead your desired output.
Pause Training - As an alternative to completely stopping a training run, the network can be paused, so training can be resumed at the same point.

(Custom Solution Wizard)

Addition of Double Precision Calculations support
