Numbered formulas of applied machine learning, each with its source
One formula per line, in the format of the Matrix Cookbook. Under every formula stand the entries of the Dictionary of Applied Machine Learning it is taken from, one textbook source pinpointed to the smallest locatable unit — a numbered result, else a section — and, for an identity, a few lines of numpy that assert it. The build runs every such check before the sheet is typeset, so a line that is printed is a line that ran.
