| - | Went over Masaki’s use of 3D plots for zenith-angle normalized plots, etc. | ||
| - | He used his own parsing for the date | ||
| - | Use of np.meshgrid() and Axes3D() | ||
| - | New explanation of basics of linear regression/machine learning. | ||
| - | W is the slope | ||
| - | b is the intercept | ||
| - | X [n x m] | ||
| - | 2D matrix of inputs (row = sample; column = data) | ||
| - | W [n x 1] | ||
| - | 1D column of weights | ||
| - | D [m x 1] | ||
| - | 1d column of stuff | ||
| - | Y = XTW + b*1 (where 1 is a 1 column vector) | ||
| - | E = D - Y | ||

| - | Explanation of math | ||
| - | Handout with math and functions and documentation. | ||
| - | Functional specification | ||
| - | Focus on “legacy” and the base for continuation. | ||
| - | Go by “black box” before understanding. | ||
| - | PDFs or slides for presentation | ||
| - | 1. We want reference for code and the supporting concepts. | ||
| - | 2. We want to focus on learning specific algorithms. | ||
| - | 3. We want to have material to have a sense of continuation and legacy in a project and also to support understanding and learning. | ||
| - | Setup for continuity and focus on code. | ||
