Feature Scaling: a preprocessing step in machine learning that involves transforming the input features to a common scale, typically to improve the performance of machine learning algorithms. It is important to keep features on a similar scale, ex ) x1 is range 0

Polynomial: a mathematical expression consisting of variables (usually represented by x), coefficients, and exponents (powers) that are combined using arithmetic operations such as addition, subtraction, multiplication, and division. Polynomial Regression : a type of regression analysis in which the relationship between the independent variable (x) and the dependent variable (y) is modeled as an..

Gradient Descent and Normal Equation are two popular techniques used in machine learning for finding the optimal parameters of a model. Gradient Descent is an iterative optimization algorithm that tries to minimize the cost function by adjusting the model parameters in the direction of steepest descent of the cost function. It starts with an initial guess of the model parameters and iteratively ..

*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..

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..
