The 2018 Linear Algebra Workshop is offered as part of the PI4 program, and will be led by Stefan Klajbor Goderich. The goal of the workshop is to review and learn some advanced linear algebra with an eye towards applications and the Computational Bootcamp, which runs immediately after this workshop.

**What is the format of the workshop?**

Students work in groups through the worksheets (see files below). Informal presentations and discussions on the most important problems occur throughout the day. The style is informal, with students working in a collaborative environment.

**How are the worksheets structured?**

Each day’s worksheet contains a list of definitions, theorems, and exercises (about 40 each day). Some of the problems were modified from those in the references, while others are problems written for this working group.

**Day 1 Worksheet**(tex file, tex label index, pdf file)

Projections and the Gram-Schmidt Process

QR Factorization

Least-squares

Linear Models: Regression**Day 2 Worksheet**(tex file, tex label index, pdf file)

Diagonalization

Symmetric matrices

Spectral Theorem

Quadratic Forms

Singular Value Decomposition**Day 3 Worksheet**(tex file, tex label index, pdf file)

Principal Component Analysis and Dimensional Reduction

Brief look at Markov Chains

LU Factorizations

Duals and annihilators

Some multilinear algebra

The “tex label index” files are useful when editing the tex files, as they list the labels used in the tex code.
