How do we decide how many neurons per layer to use (apart from input and output layer) in hidden layers and how many layers do we use in the model?

A general rule: Only add as much complexity as is needed to get good enough results. Tips: start with one hidden layer. Add more only if necessary. for the number of units in the hidden layer, two rules-of-thumb are a) the square root of the number of input features, and b) the average between t…
