math

The last time I studied math seriously was in a Linear Algebra module in university 4 years ago. Recently taking a course on NLP and Deep Learning, hence, I’m documenting the math concepts I found useful. Jacobian Matrix The Jacobian matrix is essentially a way to capture how a function scales, rotates, or distorts space locally around a point $x$ when it maps from one set of variables to another. Essentially, it is just a matrix where each entry is a partial derivative of an output with respect to an input....
