![]() ![]() Get a feel for the idea, graph visualization, mean squared error equation.The fact that MSE is almost always strictly positive (and not zero) is because of randomness or because the estimator does not account for information that could produce a more accurate estimate. MSE is a risk function, corresponding to the expected value of the squared error loss. This is the definition from Wikipedia: In statistics, the mean squared error (MSE) of an estimator (of a procedure for estimating an unobserved quantity) measures the average of the squares of the errors - that is, the average squared difference between the estimated values and what is estimated. We will define a mathematical function that will give us the straight line that passes best between all points on the Cartesian axis.Īnd in this way, we will learn the connection between these two methods, and how the result of their connection looks together. The example consists of points on the Cartesian axis. This article will deal with the statistical method mean squared error, and I’ll describe the relationship of this method to the regression line. ![]() By Moshe Binieli Machine learning: an introduction to mean squared error and regression lines Introduction image Introduction ![]()
