如何在python中使用广义回归神经网络？

Question

我试图找到任何使用python实现newgrnn (Generalized Regression Neural Network)的python库或包。在

有没有可以使用神经网络进行回归的软件包或库。我试图找到与这里描述的newgrnn (Generalized Regression Neural Network)等价的python。在

我找到了解决我问题的neupy图书馆：

from neupy import algorithms
from neupy.algorithms.rbfn.utils import pdf_between_data

grnn = algorithms.GRNN(std=0.003)
grnn.train(X, y)

# In this part of the code you can do any moifications you want
ratios = pdf_between_data(grnn.input_train, X, grnn.std)
predicted = (np.dot(grnn.target_train.T, ratios) / ratios.sum(axis=0)).T
