Nettet10. jan. 2024 · Techniques of Supervised Machine Learning algorithms include linear and logistic regression, multi-class classification, Decision Trees and support vector machines. Supervised learning requires that … Nettet9. jun. 2024 · Gradient descent is a first-order optimization algorithm. In linear regression, this algorithm is used to optimize the cost function to find the values of the βs (estimators) corresponding to the optimized value of the cost function.The working of Gradient descent is similar to a ball that rolls down a graph (ignoring the inertia).

NettetWhy Linear Regression? •Suppose we want to model the dependent variable Y in terms of three predictors, X 1, X 2, X 3 Y = f(X 1, X 2, X 3) •Typically will not have enough data to try and directly estimate f •Therefore, we usually have to assume that it has some restricted form, such as linear Y = X 1 + X 2 + X 3
