WebPCA本质上是通过特征的线性组合将它们重新排列。 因此,它被称为特征提取技术。 PCA的一个特点是第一个主成分包含有关数据集的最多信息。 第二个主成分比第三个主成分提供更多信息,依此类推。 为了阐述这个想法,我们可以从原始数据集中逐步删除主成分,然后观察数据集的样子。 让我们考虑一个特征较少的数据集,并在图中显示两个特征: 这是只 … This is a Python implementation of the Instrumtented Principal Components Analysis framework by Kelly, Pruitt, Su (2024).

Principal component analysis is a fast and flexible unsupervised method for dimensionality reduction in data, which we saw briefly in Introducing Scikit-Learn . Its behavior is easiest to visualize by looking at a two-dimensional dataset. Consider the following 200 points:
