I learn mse
In statistics, the mean squared error (MSE) or mean squared deviation (MSD) 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 the actual value. MSE is a risk function, corresponding to the expected value of the squared error loss. The fact that MSE is almost always strictly positive (and not zero) is because of randomness or beca… Web10 aug. 2024 · Mean Squared Error (MSE) is a machine learning metric for regression models, but it can be confusing to know what a good value is. In this post, I will explain what MSE is, how to calculate it, and what a good value actually is. What is MSE? Mean Squared Error (MSE) is the average squared error between actual and predicted values.
