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...

1. We can choose δx = 0, δy = δ. The equation of the ellipse x = cosθ cosωt y = sinθ cos(ωt − δ) reads in Cartesian coordinates The direction of the axes is obtained by looking for the eigenvectors of the matrix which make angles α and α + π/2 with the x-axis, where α is given by tanα = cosδ tan2θ The vector product of the position ~r with the velocity ~v, ~r ×~v, is easily seen to be so that the sense of rotation is given by the sign of the product sin2θsinδ...

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.

Traditional ways of doing sciences consist of two major paradigms: by theory and by experiment. With the steady increase in computer power, there emerges a third paradigm of doing sciences: by computer simulation. Numerical algorithms are the very essence of any computer simulation, and computationa...
