Dear Sir, Please briefly describe your problem. 

how can I fix the updated weight after finishing training . after  that this the network is  use for  testing only (best network is built  so last updated weight and bias are to be fixed)??

Hi Lila,

If you have used matlab to create your ANN, you can save it using the save function. 

For example,

If you want to save your ANN in drive E: , you can save it as follows.

save E:\name_of_the_ann_object

After you saving it, you can use your saved ANN any time using the load function. 

you can load it by calling => load E:\name_of_the_ann_object

Regards.

Thank  you , sir,

But after loading  file again we need to retrain or not ?? if again retrain it again (chose random weight ). One thing I am confusing is when the dataset retrain then it again adapt random weight and (in matlab when run the program)  so previous weight again change which command is to be used ??

Hi Lila

After saving your trained ANN object, you do not have to train it again. You just have to load the ANN object and start using it.

Do not run the train function. Just use the sim function to simulate an output for a particular input vector.

Ex:

output=sim(ANN_object_name, [input vector] )

Regards.
