Solution
The RProp (Resilient Propagation) algorithm's weight update rule is unique in that it does not directly consider the value of the gradient, but only its sign. The weight update in RProp is determined based on the consistency of the sign of the gradient. If the sign of the gradient remains consistent across iterations (i.e., it does not change), the update value is increased, promoting faster convergence. If the sign of the gradient flips (i.e., it changes), the update value is decreased to allow for more fine-grained updates.
So, none of the options a, b, c, or d accurately describe the weight update rule of the RProp algorithm.
