What is UNTRUE of hidden layers of neurons in a neural network model?
A) Depending on the software used, there may be more than one hidden layer.
B) It is possible to design a neural network with direct connections from the input to the output layer, skipping the hidden layer.
C) The more neurons in hidden layers, the better the resulting model fit.
D) Activation rules govern the firing of neurons.

Question

Quizplus · Accepted Answer

Finding the optimal number of hidden layers and neurons is one of the empirical matters investigated when tuning a neural model. Depending on the problem, more neurons may actually diminish fit. A is true, though the nnet program only supports one. B is true, though not all programs support skip layers (nnet does, neuralnet does not). D is true. Common activation functions are sigmoid (often the default), tanh, and ReLU.
