how many neurons in the second layer of an neural network when is a second hidden layer needed? when is a second hidden layer necessary which layer of a neural network is a better one? why can't you add the second layer to your feed forward neural network? when is a second layer needed why do i need more than one neural layer why is there an algorithm for multilayer neural networks what type of neural network uses the genetic algorithm to select the number of neurons in the first and second layer? when do you need more than one layer of a single neural network when is a second layer of neural network necessary what's the difference between a multi-layer neural network and a one-layer neural network? why is a single layer neural network necessary? if the function is smooth can the network be performed on multiple layers when is a second layer of neural network needed if a network has more than one layer is the best? why is a multi-layer neural network better? what is the difference between multi-layer and single layer neural networks? why would a single layer neural network need additional layer when is a second layer required
