According to "Introduction to Neural Networks with Java By Jeff Heaton", the input to the Kohonen neural network must be the values between -1 and 1.
It is possible to normalize inputs where the range is known beforehand:
For instance RGB (125, 125, 125) where the range is know as values 0 and 255:
1…
