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… WebFeb 19, 2024 · In both the classification 4 testing samples are selected and for every testing samples 5 training areas are given. This selected area is chosen on the basis of ground truth data. Once these training samples are selected, then it runs and the results of both supervised Wishart and SVM classifier shown in the Fig. 3 (a) and (b).
