Q1.Why can mean squared error loss with a sigmoid activation lead to slow learning during initial training?
mcqBecause the derivative of sigmoid approaches 0 for saturated predictions, causing the gradient to vanish
Because squared error produces negative numbers for probabilities
Because mean squared error requires matrix inversion
Because sigmoid outputs are not bounded
