In which phase of training is dropout apBoth L1 and L2 regularization has the same penalty term i,e, the absolute sum of the coefficients The absolute sum of the coefficients and the square of the magnitude of the coefficients The absolute sum of the coefficients and the square root of the magnitude of the coefficients The square of the magnitude of the coefficients and the sum of the coefficientsplied in neural networks? Only during the backward pass Only during the validation phase Only during the forward pass Both during the forward and backward passes
