how do you train a neural network what kind of neural network can be trained with supervised learning what is the difference between supervised and supervised training what is the difference between supervised learning and pre-teaching deep neural networks? why are classification layers converged why do we use supervised training when to pre train neural networks when do you pre train the classification layers? why do you pre-train layers why do we train classification layers using supervised learning when should supervised learning be performed on neural networks can we train classification layers why is pre-training used before supervised learning why should the classification layers always be trained when supervised learning is performed what happens to the classification layer? can supervised learning be performed without pre-teaching? is it safe for training neural networks without supervised training? when is it healthy to pre-train a deep neural network why do we pre train neural networks is it normal to pretrain a neural network
