Compute the Gradient 1 point possible (graded) The gradient L ( x , ) is a vector with n components: L ( x , ) = 1 L ( x , ) n L ( x , ) . (Note that we are treating x as a constant and also differentiating w.r.t. to .) Let L ( x , ) = log ( 1 exp ( x ) ) . (Notice that here the log function is the natural logarithm.) Evaluate the gradient L ( x , ) . Which of the following is its j th component? exp ( x ) 1 exp ( x ) x j exp ( x ) 1 exp ( x )
