Lecture
Similar to this, this, and possibly more.
Practicum
We discuss the motivation for applying transformations to data points visualized in space. We talk about Linear Algebra and the application of linear and non-linear transformations. We discuss the use of visualization to understand the function and effects of these transformations. We walk through examples in a Jupyter Notebook and conclude with a discussion of functions represented by neural networks.
