RBF神经网络代码python

RBF神经网络的Python代码可以参考以下实现技巧：

import numpy as np
from scipy.spatial.distance import cdist

class RBFNetwork:
    def __init__(self, num_centers, sigma):
        self.num_centers = num_centers
        self.sigma = sigma
        self.centers = None
        self.weights = None

    def fit(self, X, y):
        # 选择中心点
        self.centers = self._select_centers(X)
        
        # 计算权重
