在Elbow Plot(肘部图)中选择拐点是一个关键步骤,尤其是在进行主成分分析(PCA)时,以确定保留多少个主成分(PC)最为合适。以下是如何在Elbow Plot中选择拐点的详细步骤和考虑因素: 1. 了解Elbow Plot的定义和用途 Elbow Plot用于展示不同数量主成分对数据集方差解释能力的变化。通常,随着主成分数量的增加,解释的方差...
ElbowPlot 通过绘制主成分的解释方差,寻找“肘点”(方差显著下降的拐点)以确定重要的主成分数量。 结果: 图中每个点表示一个主成分的方差解释比例。 “肘点”是解释方差增量开始显著减缓的位置,通常认为肘点之前的主成分是显著的。 适用场景: 用于快速评估主成分的重要性。 适合数据质量较高且信号较强的情况。 优...

Elbow Plot – ValueError: x and y must have same first dimension 本问题已经有最佳答案,请猛点这里访问。 我想为从 excel 文件中读取的预处理数据集生成肘部图。在下一步中,我想使用 matplotlib 包中的 plot 方法生成一个肘部图。执行代码后出现以下错误: ...
