3. 算法流程 code 版 def fit(self, X, y): # Initialization # Compute y*f(x) , Error vec E , KKT offset while True: # select idx1, idx2 to be optimized # 会有很多个 idx1,把它们存在一个列表里, # 每个 idx1 会对应很多个 idx2,同样存储在列表里 # loop for i in idx1: cnt...
_kernel == 'poly': return (sum([x1[k]*x2[k] for k in range(self.n)]) + 1)**2 return 0 我们最终的输出函数为: g(x)=\omega^{\top}x+b=\sum_{i=1}^{m}{\alpha_{i}y_{i}\phi^{\top}(x_{i})\phi(x)}+b=\sum_{i=1}^{m}{\alpha_{i}y_{i}K(x_{i},x)}+b...

Talk is cheap, let's check the code ^_^ 支持向量机 - SMO算法 - 核技巧 - 高斯核函数 支持向量机中涉及到较多的算法,比如最优化拉格朗日向量的SMO算法,将非线性可分的数据集映射到高维空间的核函数等,建议先熟悉理论,然后自己写一下算法的大致流程,再开始写代码。 ''' 支持向量机 --- 数据集:Mnist ...
