Next i present you snippets of text from a paper named " Neural Approach for Automatic Identification of Induction Motor Load Torque " from the author Alessandro Goedtel. All i'm doing is trying to redo the procedure. I think you can help me build the process according to it. Remember: Inputs: Voltage , Current and Speed Output: Torque Training Curves (extracted from simulink): 13 Testing Curves for validation: 13 Note: He used 100 pairs of input-output .. i'm using 5000 pairs.
>>(...)Each curve set, simulating a specific load from 5% to 250% of nominal torque, is >>composed of a vector constituted of 100 input-output pairs, which represent the >>transient and steady behavior of the motor for one specific load and a voltage range.(...)
>>(...) During the training process, the input-output pairs representing the process behavior >>are sequentially presented to the network(...)
What can i understand from"sequentially present" the pairs input-output? Could you give an example on how to do it?

Ok. Once i have done for one type of load, i can do for all the other types. The problem: i'm still wondering how he built the training process for those 13 curves and even how he could validate for other 13 curves. All the tips given from above is that he used "other operating configurations that were absent during the training process". What kind of "configuration" could be it? (Show me an example, please) I'm concerned on how to build all the training and testing process into the neural net. Hope it's more clear for you to understand what i'm trying to do. If you can show me examples for your exaplanation it would be easier for me to understand. And sorry for my bad english anyway...
