Neural network source code in Excel VBA

[JBpalis]

Hello,

I want to forecast economic and financial time series data using a
neural network in Excel VBA. I need access to the source code.

Can anyone recommend either (a) VBA neural network solution that
offers access to source code (free or fee), or (b) a third-party
developer who has done work in this area?

I am familiar with TiberiusXL, but wonder if there are others.

(And I understand that Excel/VBA is not the ideal development platform
for a neural network implementation! But in this case I have to dance
with the one I brung.)

Thanks,
JB

NeuroSolutions has two options that might meet your needs:

1. NeuroSolutions 6 with the Custom Solution Wizard. This will allow
you to design a neural network within the GUI of NeuroSolutions and
then deploy the NN into an Excel application written in VBA. However,
the neural network is a compiled DLL and not source code.
2. NeuroSolutions 6 Developers with the Source Code License. This will
allow you to design a neural network within the GUI of NeuroSolutions
and generate C++ source code for the NN. This code would then need to
be compiled and integrated with your VBA application.

Hi JB,

TiberiusXL was designed as a tool to give those who want to develop
neural nets in VBA a starting point - it contains what to some would
be the hard bits - the learning algorithm. It was never meant to
actually be used as a fully functioning bit of software.

If you want to just 'deploy' a neural net model in excel VBA then
TiberiusXL has a big brother that might help you. Tiberius is a stand
alone application that will build thew nn model and then with the
click of a button it is exported to Excel. You then just need to paste
your new data in the sheet and the 'predictions' will then appear. The
nn 'equation' is stored as a formula - you have access to this formula
in the VBA code.

If you want me to develop something custom for you then this can be
arranged.
