What is PCA? (5 key points) Principal Component Analysis is a statistical technique used for dimensionality reduction, crucial when dealing with high-dimensional data in machine learning. It works by transforming original variables into new ones, called principal components, which are linear combinations of the original variables. Key Points: 1. Principal Components: Principal components are the directions in the data that maximize variance. The first principal component captures the most...

Linear Algebra is a fundamental branch of mathematics that explores vector spaces, linear transformations, and systems of linear equations. This course introduces students to key concepts such as matrix operations, determinants, eigenvectors, and eigenvalues. Through a combination of theory and practical applications, students develop the skills to solve complex problems and analyze real-world phenomena using linear algebraic methods from these notes.

If the columns of A are linearly dependent - correct answer Then the matrix is not invertible and an eigenvalue is 0 Note that A−1 exists. In order for λ−1 to be an eigenvalue of A−1, there must exist a nonzero x such that Upper A Superscript negative 1 Baseline Bold x equals lambda Superscript negative 1 Baseline Bold x . A−1x=λ−1x. Suppose a nonzero x satisfies Ax=λx. What is the first operation that should be performed on Ax=λx so tha...
