5.5 Mean Squared Error (MSE) Similar to MAE, mean squared error is another metric used in regression-based sentiment analysis tasks. It calculates the average squared difference between the predicted sentiment values and the true sentiment values. MSE amplifies the impact of large errors, making it...
We consider this problem in a regression framework by considering a ridge logistic regression (RR) with three alternative ways of shrinking the estimates of the event probabilities. While it is shown that all three variants reduce the mean squared error (MSE) of the MLE, there is at the same...

The formula for the mean squared error is MSE = Σ(yi − pi)2/n, where yi is the ith observed value, pi is the corresponding predicted value for yi, and n is the number of observations. The Σ indicates that a summation is performed over all values of i. If the prediction passes...
For example, inregression, the mean squared error represents the average squaredresidual. As the data points fall closer to the regression line, the model has less error, decreasing the MSE. A model with less error produces moreprecise predictions. ...

This article mainly aims to study the superiority of the notion of linearized ridge regression estimator (LRRE) under the mean squared error criterion in a linear regression model. Firstly, we derive uniform lower bound of MSE for the class of the generalized shrinkage estimator (GSE), based on...

Root mean squared (Error|Deviation) in case of regression. The RMSD represents the sample standard deviation of the differences between predicted values and observed values. The RMSE serves to aggregate the magnitudes of the errors in predictions into a single measure of predictive power. RMSE...
