Tutorial on PCA and approximate PCA and approximate kernel PCA
Overview
Paper Summary
This paper provides a tutorial on Principal Component Analysis (PCA) and its variations, including approximate PCA for large datasets and kernel PCA for nonlinear data. It discusses the mathematical foundations of these methods and presents algorithms for their implementation, focusing on reducing computational costs in different scenarios like small sample size, large datasets, and high-dimensional spaces.

Rating Explanation
The paper provides a comprehensive tutorial on PCA, approximate PCA, and approximate kernel PCA. Its strength lies in the clear explanation of the mathematical foundations and the practical algorithms for handling different data scenarios. The inclusion of code examples is also a valuable addition. However, the limited performance evaluation and lack of in-depth discussion of real-world applications prevent it from receiving a higher rating.
