本文简要介绍python语言中 sklearn.metrics.plot_confusion_matrix 的用法。 用法: sklearn.metrics.plot_confusion_matrix(estimator, X, y_true, *, labels=None, sample_weight=None, normalize=None, display_labels=None, include_values=True, xticks_rotation='horizontal', values_format=None, cmap='...
我对Python和深度学习还不熟悉,我训练了一个多分类器模型并想要画出混淆矩阵,但是遇到了一个错误。以下是我的代码: from sklearn.metrics import plot_confusion_matrix import matplotlib.pyplot as plt from sklearn.metrics import ConfusionMatrixDisplay Y_pred = model.predict_generator(test_generator) y_pred...

Numpy、Python、Matplotlib Plot和Sparse Matrix Pattern是Python编程中非常重要的主题之一。Numpy提供了一种灵活的方式来处理数组和矩阵,Python是一种易于学习和理解的编程语言,Matplotlib Plot使我们能够将数据转化为易于理解的图表,而Sparse Matrix Pattern允许我们仅存储非零元素,从而节省空间和提高计算效率。在Python编程...
要显示矩阵,首先需要将矩阵数据导入Python中。通常使用NumPy库来处理矩阵数据。下面是一个简单的示例,创建一个3x3的随机矩阵并使用Matplotlib显示: importnumpyasnpimportmatplotlib.pyplotasplt# 创建一个3x3的随机矩阵matrix=np.random.rand(3,3)# 显示矩阵plt.imshow(matrix,cmap='viridis')plt.colorbar()plt.show...
