New Excel/VBA neural network
Phil Brierley
Visual Basic/VBA is not the language a purist would choose to code a
neural network in, as it is relatively slow compared with other
languages.
Nevertheless, for development, investigation and research purposes it
can be pretty useful, easy to understand and is readily accessible in
applications such as Excel and Access - you could even code a neural
network to run in Word if you really wished.
In fact the most popular search engine term for people arriving at my
web site looking for neural network code includes 'Visual Basic'.
Anyway, I have finally gotten around to tidying up an Excel neural net
developed a while ago. This is ideal for investigators who want some
basic starting code and who want to develop in VBA or VB. In fact all
the neural functions are translated from c++ dlls so it will be pretty
easy if you want to translate them back and gain a bit of speed - you
can still keep the Excel front end.
Please download it and have a play - it uses the graphical
capabilities of Excel to plots some neat graphs that lets you see
exactly what the net is doing.
If you want to access the code modules then details are on the web
page - I'm not decided yet wether this will be a freeby as it is a bit
too developed into a 'product'.
The zip file is tiny and can be downloaded from
