I asked yesterday, but I don't understand. because I used neural network matlab tool first time
So I ask you again
1. error values don't have to minus value??
2. What is the y axis? is it the number of traning, validation and test data set?
3. why the highest bar exist? is it mean highst bar has 0.001502 error values?
4. what is zero error? I don't understand zero error line means. it means 0? it means distribution which bar close 0?
Is it best performance??? what does mean in this graph??
I'm sorry for many questions.. Thank you in advance.
