[OpendTect_Users] Seismic Attribute Normalization

[Paul de Groot]

Hello Mohsen,

I assume that you use the Unsupervised Vector Quantizer (UVQ) neural network
from OpendTect's neural networks plugin. If so, then there is no need for
normalizing the input attributes. The software automatically scales all
input attributes to fall within a dynamic range from 0 to 1.

Best regards,

Paul.
