Abstract :
In this paper, the sensitivity of Adalines to weight perturbation is discussed. According to the discrete feature of Adalines´ input and output, the sensitivity is defined as the probability of an Adaline´s erroneous outputs due to weight perturbation with respect to all possible inputs. By means of hypercube model and analytical geometry method, a heuristic algorithm is given to accurately compute the sensitivity. The accuracy of the algorithm is verified by computer simulations.
