SNN 核函式的2種形狀

畫出k的形狀

    def Plot_k(self,tau = 1):
        s = np.random.random(500)* 10  
        value = s / self.tau * np.exp(1 - s / self.tau)
        plt.scatter(s,value,c='r',alpha=0.3,marker = '*')
        plt.show()

    def Plot_kk(self,tau = 1, tau_s = 0.25):
        s = np.random.random(500)*10
        value =  (np.exp(-(s) / self.tau) - np.exp(-(s) / self.tau_s))
        plt.scatter(s,value,c='g',alpha=0.3,marker = '*')
        plt.show()
