有时为了方便,将权值向量和输入向量加以扩充,仍然记为ω和x,但是ω=(ω1 ,ω2 , . . . , ωn ,b )T,x = (x1,x 2 , . . . , x n , 1 ) T。在这种情况下,二项逻辑回归模型如下: P(Y=0∣x)=1/(1+eω⋅x)P(Y=1∣x)= eω⋅x/(1+eω⋅x)定义sigmoid函数为 sigmoid(z)...

1. 对速度进行初始化,对粒子的位置进行初始化,这里粒子的位置采用的二进制的表示方法。1表示选择该物体,0表示不选择该物体。其他的参数的初始化的过程与前面的方法一样。 源代码: clc; clearall; NP =100; % 种群个数 G =200; % 迭代次数 D =10; % 决策变量的维度 ...
Since P(∞,r)=0 and P(0,r)=1, it follows that m0(r)=P(0,r)−P(∞,r)=1. Differentiating both parts of Eq. (5.20) with respect to τ, multiplying by exp(iντ) and integrating over τ from 0 to ∞, we obtain the following equation for the characteristic function Θ(iν...
