Hello everybody

the result of my CNN is shown in the picture attached. I'm wondering about the accuracy why it goes down and up during the training? is it normal or it should grow gradually? and what is the possible error that may I have on my net (or parameters)!! Additionally, whatever I change the training options; the test accuracy does not exceed 42% !!!

if true
