使用python实现ANN
ANN算法的Python实现可以使用scikit-learn库中的MLPClassifier类来实现。首先,我们需要加载数据集,可以使用sklearn.datasets中的load_iris函数,该函数加载了鸢尾花数据集,并将其分为属性和标签。然后,我们可以使用np.random.permutation函数生成一个随机序列,用于拆分训练集和测试集。接下来,将数据集分为训练集和测试集,可以选择将后10个数据作为测试集。最后,我们可以实例化MLPClassifier类,并使用fit方法来拟合训练数据。以下是ANN算法的Python实现的代码示例:
```
from sklearn import datasets
import numpy as np
from sklearn.neural_network import MLPClassifier
np.random.seed(0)
iris = datasets.load_iris()
iris_x = iris.data
iris_y = iris.target
indices = np.random.permutation(len(iris_x))
iris_x_train = iris_x<span class="em">1</span><span class="em">2</span><span class="em">3</span>
