This is the first time I'm posting anything on this net, so I was not
able to retrieve the address of the person who wanted to know about
existing text recognition software using neural nets.
I have a program which implements Grossberg's ART1 (with some modifications)
for text recognition. It is still rudimentary, but is capable of adaptively
learning to recognize a bit-mapped set of characters at its input. Access after
learning is virtually instantaneous, and the number of characters it can store
depends on how many connections you can simulate in your machine. I have tried
the program with a large number of input nodes and there are no problems. The
time taken by the network to learn (I refer to real time, as in the time taken
if the network were to be built in hardware) does not scale up to any great
degree with the number of nodes (CPU time obviously does).
