The N. A. Technologies Neural Network Development Process is an improvement from previously used virtual welding training software used in the different shipyards I was referring to in another post in the Technical section of this forum... A terrible .ppt in .pdf (I apologize for this) so, at times it can be confusing but after careful reading, one can see the merits in the improved software... It's worth the read @ the very least so check it out... Enjoy!
