Lecture 2: Another Perspective on PCA

In the previous lecture, we introduced PCA from a statistical perspective. In this lecture, we will explore PCA from another viewpoint. First, I will introduce a new way of understanding datasets. Then, using this fresh perspective, we will explain the concept of image reconstruction through a concrete example. Finally, we will use this concept to reformulate PCA.
