5. (1) Suppose that we are performing a gradient descent algo- rithm with the learning rate a = 0.03 for 15 iterations. If the gradient still decreases after the 15 iterations, choose the best conclusion from the following: a) Increase the learning rate (a = 1.0) b) Decrease the learning rate (a = 0.1) c) There is no problem with the learning rate (a = 0.3) (2) Suppose that we are performing a gradient descent algo- rithm with the learning rate a = 0.03 for 15 iterations. If the gradient (6) decreases and becomes stable, choose the best conclusion from the following: a) Increase the learning rate (a = 1.0) b) Decrease the learning rate (a = 0.1) c) There is no problem with the learning rate. (a = 0.3)
