In this video, I break down exactly what Principal Component Analysis (PCA) is, what a principal component really means, and how to interpret the results to reduce dimensionality without losing important information. Then, I walk through how principal components are actually constructed, covering the key mathematical ideas behind PCA.
If you’ve ever found PCA confusing or abstract, this video is designed to make it finally click, with a clear explanation of both the intuition and the math.
