CS 189 Spring 2020 Introduction to Machine Learning Final Exam • The exam is open book, open notes, and open web. However, you may not consult or communicate with other people (besides your exam proctors). • You will submit your answers to the multiple-choice questions through Gradescope via the assignment “Final Exam – Multiple Choice”; please do not submit your multiple-choice answers on paper. By contrast, you will submit your answers to the written questions by writing them...

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...

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.

PCA Questions and Answers Question: PCA stands for Principal _________ Analysis. Component Difficulty: Easy Explanation: PCA stands for Principal Component Analysis. It's a dimension reduction technique that enables you to identify the most significant underlying structure of your data. Question: PCA aims to find a new set of dimensions such that all the dimensions are _________ and the variance is maximized. Orthogonal Difficulty: Medium Explanation: In PCA, the goal is to find...

Allow me to show you how to solve eigenvectors with finesse. Typically we use row-reduction to solve for eigenvectors, but I will show you a nice property of linear transformations and the kernel.
