WebOne way to avoid it is to change the cost function to use probabilities of assignment; p ( y n = 1 x n). The function becomes. 1 N ∑ n y n p ( y n = 0 x n) + ( 1 − y n) p ( y n = 1 x n). This function is smoother, and will work better with a gradient descent approach. You will get a 'finer' model.
