本文介绍了使用Keras进行非线性回归的代码实践，包括如何解决ImportError问题以及展示了一个训练过程，展示了损失(loss)随训练迭代逐渐降低的过程。

一、ImportError: cannot import name 'SGD' from 'keras.optimizers'

怎么解决？

代码如下：

import keras
import numpy as np
import matplotlib.pyplot as plt
from keras.models import Sequential
from keras.layers import Dense,Activation
from keras.optimizers import SGD
#from tensorflow.keras.optimizers import SGD

x_data=np.linspace(-0.5,0.5,200)
noise=np.random.normal(0,0.02,x_data.shape)
y_data=np.square(x_data)+noise

#plt.scatter(x_data,y_data)
#plt.show()

model=Sequential()
model.add(Dense(input_dim=1,units=10))
model.add(Activation('tanh'))
model.add(Dense(units=1))
model.add(Activation('tanh'))

sgd=SGD(lr=0.3)
model.compile(optimizers=sgd,loss='mse')

for step in range(3001):
    cost=model.train_on_batch(x_data,y_data)
    if step%500==0:
        print('cost:',cost)
y_pred=model.predict(x_data)
plt.scatter(x_data,y_data)
plt.plot(x_data,y_pred,'r-',lw=3)
plt.show()

修改为：

import keras
import numpy as np
import matplotlib.pyplot as plt
from keras.models import Sequential
from keras.layers import Dense,Activation
import tensorflow as tf
from sklearn.model_selection import train_test_split

x_data=np.linspace(-0.5,0.5,200)
noise=np.random.normal(0,0.02,x_data.shape)
y_data=np.square(x_data)+noise

#plt.scatter(x_data,y_data)
#plt.show()
x_train, x_test, y_train, y_test = train_test_split(
    x_data, y_data, test_size=0.3, shuffle=True, random_state=23)
model=Sequential()
model.add(Dense(input_dim=1,units=10))
model.add(Activation('tanh'))
model.add(Dense(units=1))
model.add(Activation('tanh'))

#编译模型
ssgd=tf.keras.optimizers.SGD(lr=0.3)#设置学习率0.005
#损失函数设为：mse(均方误差)，优化器设为：SGD(梯度下降)
model.compile(loss='mse',optimizer=ssgd)

history = model.fit(x=x_train, y=y_train, batch_size=32, epochs=2000, validation_split=0.2)
y_pred=model.predict(x_data)
plt.scatter(x_data,y_data)
plt.plot(x_data,y_pred,'r-',lw=3)
plt.show()

不报错

二、另一个不报错代码为：

import tensorflow as tf
import numpy as np
import matplotlib.pyplot as plt

#生成试验数据
#x=np.linspace(-10,10,100)
#x=tf.convert_to_tensor(x)
#y=x**2+np.random.rand(100)*10
x=np.linspace(-0.5,0.5,200)
noise=np.random.normal(0,0.02,x.shape)
y=np.square(x)+noise
#建立模型
#设置层
model=tf.keras.Sequential([
    #1-2层，输入层一个神经元，隐层100个神经元，激活函数sigmoid
    tf.keras.layers.Dense(10,activation='tanh',input_dim=1),
    tf.keras.layers.Dense(1)#3层，输出层一个神经元，输出一个数
])
#编译模型
ssgd=tf.keras.optimizers.SGD(lr=0.3)#设置学习率0.005
#损失函数设为：mse(均方误差)，优化器设为：SGD(梯度下降)
model.compile(loss='mse',optimizer=ssgd)
#训练模型
model.fit(x,y,epochs=2000)#迭代2000次
print('训练结束')
#绘图
y_pred=model.predict(x)
plt.scatter(x,y)
plt.plot(x,y_pred,'r-',lw=3)
plt.show()

结果为：

如果你是小白，请慢慢看完~ 概念： 分类是数据挖掘的一种非常重要的方法。分类的概念是在已有数据的基础上学会一个分类函数或构造出一个分类模型（即我们通常所说的分类器(Classifier)）。该函数或模型能够把数据库中的数据纪录映射到给定类别中的某一个，从而可以应用于数据预测。总之，分类器是数据挖掘中对样本进行分类的方法的统称，包含决策树、逻辑回归、朴素贝叶斯、神经网络等算法。#这些算法都很重要，慢慢介绍，请看专题，一定有的！ 分类器的构造和实施大体会经过以下几个步骤： ...

多项式回归（非线性回归）的python代码实现
weixin_71894495的博客

在解决回归问题中，很多数据集中输入空间与输出空间并非完全呈线性关系，使用线性回归无法解决此类问题。为了解决存在非线性关系的数据集的回归问题，需要进行多项式回归，但sklearn并未提供多项式回归模型的类。多项式回归使用的还是线性回归的思路，它的关键在于我们为原来的数据样本添加新的特征，这些新的特征来源方式是对原来特征的多项式组合，采用这样的方式，便可以完美解决非线性问题，本文提供了三种方式进行多项式回归，在工程实践中，推荐方式三。
