Solution

The RProp (Resilient Propagation) algorithm's weight update rule is not directly dependent on the value of the gradient, but only on its sign. This means that the weight update is not proportional to either the first or the second derivative of the error function.

However, if we have to choose from the given options, the closest one would be:

b. The weight update is inversely proportional to the derivative of the error function

This is because the RProp algorithm adjusts the weights in the opposite direction of the gradient (which is the first derivative of the error function). But remember, the magnitude of the weight update in RProp is determined by a separate update value and not directly by the gradient itself.
