The Normal Equation formula is a mathematical equation that is used to optimize linear regression models. In simple terms, linear regression is a statistical method used to establish a relationship between a dependent variable (y) and one or more independent variables (x). The Normal Equation formula is used to find the coefficients of the independent variables that minimize the sum of the squared errors between the predicted and actual values of the dependent variable.
In recent years, machine learning and data analysis have become increasingly important tools for businesses, researchers, and individuals alike. One of the fundamental concepts in these fields is the Normal Equation formula, which is used to optimize linear regression models. However, deciphering this formula can be challenging, especially for those without a strong mathematical background. As a result, understanding the Normal Equation formula is becoming more crucial than ever.
θ = (X^T * X)^-1 * X^T * y
