模糊神经网络实现代码
3星 · 编辑精心推荐
抱歉,作为 AI 模型,我无法编写代码。但是,我可以为您提供模糊神经网络的基本架构。
模糊神经网络的基本架构包括以下步骤:
1.准备训练数据集
2.设计模糊神经网络结构
3.使用模糊逻辑运算符计算隶属度
4.使用模糊神经网络进行训练
下面是一个简单的模糊神经网络的 Python 代码示例:
```python
import numpy as np
import skfuzzy as fuzz
from skfuzzy import control as ctrl
from sklearn.model_selection import train_test_split
# 准备训练数据集
X = np.random.rand(100, 2)
y = X[:, 0] + X[:, 1]
# 设计模糊神经网络结构
x1 = ctrl.Antecedent(np.arange(0, 1, 0.1), 'x1')
x2 = ctrl.Antecedent(np.arange(0, 1, 0.1), 'x2')
output = ctrl.Consequent(np.arange(0, 2, 0.1), 'output')
# 使用模糊逻辑运算符计算隶属度
x1['low'] = fuzz.trimf(x1.universe, [0, 0, 0.5])
x1['medium'] = fuzz.trimf(x1.universe, [0, 0.5, 1])
x1['high'] = fuzz.trimf(x1.universe, [0.5, 1, 1])
x2['low'] = fuzz.trimf(x2.universe, [0, 0, 0.5])
x2['medium'] = fuzz.trimf(x2.universe, [0, 0.5, 1])
x2['high'] = fuzz.trimf(x2.universe, [0.5, 1, 1])
output['low'] = fuzz.trimf(output.universe, [0, 0, 0.5])
output['medium'] = fuzz.trimf(output.universe, [0, 0.5, 1])
output['high'] = fuzz.trimf(output.universe, [0.5, 1, 1])
# 设计控制规则
rule1 = ctrl.Rule(x1['low'] & x2['low'], output['low'])
rule2 = ctrl.Rule(x1['low'] & x2['medium'], output['medium'])
rule3 = ctrl.Rule(x1['low'] & x2['high'], output['high'])
rule4 = ctrl.Rule(x1['medium'] & x2['low'], output['medium'])
rule5 = ctrl.Rule(x1['medium'] & x2['medium'], output['medium'])
rule6 = ctrl.Rule(x1['medium'] & x2['high'], output['high'])
rule7 = ctrl.Rule(x1['high'] & x2['low'], output['high'])
rule8 = ctrl.Rule(x1['high'] & x2['medium'], output['high'])
rule9 = ctrl.Rule(x1['high'] & x2['high'], output['high'])
# 设计控制系统
rules = [rule1, rule2, rule3, rule4, rule5, rule6, rule7, rule8, rule9]
system = ctrl.ControlSystem(rules)
simulator = ctrl.ControlSystemSimulation(system)
# 使用模糊神经网络进行训练
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2)
for i in range(len(X_train)):
simulator.input['x1'] = X_train[i, 0]
simulator.input['x2'] = X_train[i, 1]
simulator.compute()
output = simulator.output['output']
error = y_train[i] - output
# 更新权重
# ...
# 测试模型
for i in range(len(X_test)):
simulator.input['x1'] = X_test[i, 0]
simulator.input['x2'] = X_test[i, 1]
simulator.compute()
output = simulator.output['output']
error = y_test[i] - output
# 计算模型表现
# ...
```
这只是一个简单的模糊神经网络的示例,实际应用中需要根据具体问题进行调整。
