Glad to see you reply.
But in neural networks context, when people say that the NN model takes hours or days or months to learn from data, so that means execute the same model with same weights and bias lot of times.
Or on each time will they tweak and tune those parameters.
And when , you did the coding for face recognition, may I know how long you’ve been working to get the model to get the higher accuracy.
The very first time or we have to spent some time with it?
I am sorry for bothering you so very much!
