An input signal of unit amplitude is applied repeatedly to a synaptic connection whose initial value is also unity. Calculate the variation in the synaptic weight with time using the following two rules: (a) The simple form of Hebb's rule described in Eq. (2.9) assuming the learning-rate parameter n = 0.1. b) The covariance rule described in Eq. (2.10), assuming that the presynaptic activity r = 0 and the postsynaptic activity y = 1.0.

An input signal of unit amplitude is applied repeatedly to a synaptic connection whose
initial value is also unity. Calculate the variation in the synaptic weight with time using
the following two rules:

(a) The simple form of Hebb's rule described in Eq. (2.9) assuming the learning-rate
parameter n = 0.1.
b) The covariance rule described in Eq. (2.10), assuming that the presynaptic activity
r = 0 and the postsynaptic activity y = 1.0.
