*Linear : a mathematical or statistical relationship that is proportional or additive in nature. In a linear relationship, two variables are related in such a way that when one variable changes, the other variable changes proportionally. *Regression : a statistical method for modeling the relationship between a dependent variable and one or more independent variables. The goal of regression anal..

Automatic Differentiation

A general way of automatically constructing a procedure for computer derivatives numerically - a mathematical tool that allows us to compute the gradients of complex functions, including those with multiple inputs and outputs. * this is not a function or a formula, it is a mathematical procedure. Most of the times, it makes a computation graph. a computation graph is a graphical representation o..
